Battery Replacement

In preparation for my upcoming event on 25th July 2010 (Sunday), I decided to change away my "still working" battery on my BB Lion. The event which will be held in the morning and I will need to leave around 7am. In case somehow the battery decided to fail on me on that day, I'll have no where to get a replacement at that particular time of the day.

Since my "still working" battery is already over a year, I decided to take prevention steps and change it. Besides, in recent months, I've been doing a lot of short distance driving with frequent start and stop. It ain't good for the battery.

The battery I'm changing to is of Varta brand (Europe), which is one of the original brand for Peugeot cars. Basically there're variants of each size:
Black Dynamic
Blue Dynamic
Silver Dynamic

If you check out Varta official website, you can find more types. I would say the 3 different variant/types is similar to of Bosch S3, S4 and S5. My current battery is Bosch S3 of size DIN55L. I found this Varta seller from mudah.com.my; Actually, I found him last year when my battery failed on me early in the morning before leaving to work, due to time constraint, I bought the Bosch S3 from nearby tyre shop. Wanted Bosch S4, but they only have Bosch S3. This time, I have more time and choices.

The Varta battery seller is actually a battery supplier, and they also supply Bosch batteries in case anyone is interested. They also accept trade in of your old battery for a small fee. Finally, they do delivery service around Klang Valley. How good is that deal? In my opinion, superb~

I bought Varta Blue Dynamic DIN55L for RM350 and traded in my old Bosch S3 DIN55L for RM20. The boss himself came over and do the installation as his staff was not able to make it. Very nice guy, after he installed the battery, he also test and checked the battery and also my alternator to confirm everything is OK. I don't get such service when I change battery outside before, have you?

He also tested my old battery and notice my cold cranking amp (CCA) was around 280++ only, while the new one is around 600++. So, guess my old battery was also retiring soon. Oh yes, he also check my old battery manufactured date, it was somewhere in 2008, so it was also in storage for sometime before I actually bought it.

Finally, I was also given a receipt for the battery. Overall, the price is reasonable or great and the service was great~ definitely recommended! Hopefully, through this, he can give special price for all 206 owners and hope we can all help to support him for providing such good service and product.

Lastly, actually there's some important information on disconnecting and reconnecting the battery which you can find from the Internet. This applies for most modern cars with BSI, this is to prevent problems like corrupting/damage to the BSI (something like when you remove your memory card while it's being access which could lead to corrupted data or worst, your memory card). This is actually very important as there're owners with failed BSI and have to replace the entire BSI, although I'm not sure the actual caused. But why take the risk when the below simple step isn't hard to follow?

Method for unplugging/disconnecting the battery:
1. Before unplugging the battery, turn off all gadgets and lights, closing all the doors and unplugging any kind of diagnostic tool. The drivers side window has to be kept open for any kind of requirement.
2. Turn off the ignition and take out the key following which unplug the battery after an interval of
3 minutes.
3. The BSI needs to be taken to sleep mode or Active Economy mode, during which nothing in the vehicle should be operating. Even the bonnet should not be opened that time as it can 'wake up' the BSI if the vehicle has got an alarm installed.
For batteries under the bonnet, the bonnet should be opened and left up before allowing the BSI to go to Sleep Mode. During this 3 minute interval, use of any remote control central locking gadgets for other vehicles should be avoided in the vicinity of the concerned vehicle.

Method for connecting the battery:
The following procedure is for reinstalling the battery connection unless told otherwise by Peugeot or Product service. Failure to follow this procedure may result in damage to the BSI's embedded software during reconnection.
1. All the doors have to be closed with the ignition key turned off and the key taken out.
2. Now without opening the doors, replug the battery and wait for 10 seconds.
3. Turn on the headlights, turn on the engine and inspect the system's functioning.


Some good source of information about Battery:
http://autorepair.about.com/library/weekly/aa101604d.htm

Some information taken from the above site:

Batteries are perishable, so buy fresh.
Unless a battery has periodically been recharged, never buy a non-sealed wet Low Maintenance battery that is more than three months old or a sealed wet Maintenance Free battery that is more than six months old because they have started to sulfate.

"Dry charged" batteries are shipped without electrolyte, but usually have "sell by" dates of one to three years. Battery dealers will often place their fresher batteries in the rear of the rack or in a storage room. The date of manufacture is often stamped on the case or printed on a sticker. If you cannot determine the date code, ask the dealer or contact the manufacturer.

A battery will lose its charge sitting in storage.
Depending on the type of battery and temperature, batteries have a natural self-discharge or internal electro chemical "leakage" at a 1% to 25% rate per month. Over time the battery will become sulfated and fully discharged. Higher temperatures accelerate this process. A battery stored at 95° F (35° C) will self-discharge twice as fast than one stored at 75° F (23.9° C).

More RC (Reserve Capacity) or Amp Hours is a good thing.
Larger RC or Amp Hours is better because of the effects of increased parasitic (ignition key off) loads, normal battery self discharge while in long term parking or storage, and the demands of stop-and-go driving.

Amp Hours (AH) is normally used to describe the capacity of deep cycle and international car batteries. When comparing Amp Hour specifications, use the same discharge rates, expressed in hours. There is a relationship between the weight of the battery and the amount of RC or Amp Hours. A heavier battery has more lead and is normally better choice.

Size matters!
Purchasing a battery has become much easier because most of the battery and vehicle manufacturers have adopted the BCI Group Number as a standard for the battery's voltage, physical size, terminal type and terminal location. It contains the vehicle's minimum cold cranking amps (CCA) requirement and Battery Council International (BCI) Group Number replacement recommendations by make, model and year of manufacturer.

Select the battery with CCA (Cold Cranking Amps) that will meet or exceed the vehicle manufacturer's recommendation.
Do not substitute CA (Cranking Performance Amps), MCA (Marine Cranking Amps), or HCA (Hot Cranking Amps) for CCA. In hot climates, buying batteries with double or triple the cranking amps that exceeds your starting requirement is not recommended. However, in cold climates, a higher CCA rating is better, due to increased power required to crank a sluggish engine and the inefficiency of a cold battery.

A larger capacity battery will damage my car.
A starter motor will only draw a fixed amount of current from the battery, based on the resistance of its load. A larger current capacity battery supplies only what is required. It will not damage your vehicle. Using batteries with higher or lower voltage or physically too tall could potentially damage your vehicle.

Care & Maintenance:

Bad batteries may harm the charging system or starter.
A bad or weak battery causes more stress on a charging system or starter and can cause premature failures due having to compensate the voltage or current. If you replace a battery, alternator, voltage regulator or starter, you should test the other components for latent or permanent damage.

"Maintenance free" batteries VS hot climates.
In hot climates, the water in the electrolyte is lost due to the high under hood temperatures. Water can also be lost due to excessive charging voltage or charging currents. Non-sealed batteries are recommended in hot climates so distilled water can be added when this occurs.

Car batteries in hot climates & cold climates.
Car batteries last an average of two thirds as long in hot climates as cold ones. Heat kills car batteries, especially sealed wet Maintenance Free batteries and cold reduces the battery's starting capacity.

DO NOT test the alternator by disconnecting the battery with the engine running.
A battery acts as a voltage stabilizer or filter to the pulsating DC produced by the alternator. Disconnecting a battery while the engine is running can destroy the sensitive electronic components connected to the electrical system such as the emission computer, audio system, cell phone, alarm system, etc., or the charging system because the peak voltage can rise to 40 volts or more. In the 1970s, removing a battery terminal was an accepted practice to test charging systems of that era. That is not the case today.

Pulse chargers, aspirins or additives will revive sulfated batteries? Myth Or Fact?
Using pulse chargers or additives is a very controversial subject. Most battery experts agree that there is no conclusive proof that pulse chargers work any better than constant voltage chargers to remove sulfation. They also agree that there is no evidence that additives or aspirins provide any long-term benefits. Short term gains are achieved by increasing the acidity of the battery, but this will damage the battery plates.

Abit ugly.. but nice try :)

Custom Exhaust System

Ever heard of a badly modified exhaust sound? It's noisy and annoying; this is exactly how it sounded when my BB Lion's exhaust pipe cracks. The sound is horrible, the performance drops and it's a shame on the road, plus for those that didn't know, will thought you modified your car and wants to race you! The cracks happen on weekday and I have to endure the whole week until the weekend before I can get it repaired.

To cut the story short, in total the crack happen 3 times, each happen after some time of the previous repair, and the cracks happen on the same line after the crack as if it will break apart. After repairing the cracks on my exhaust pipe twice, finally I change the whole Exhaust System on the third crack.

For the first incident, since it was repaired, I decided to change when it happen again, but the second time it happen at not-so-good time where festive season is near and when I'm busy. So, after getting the quotation of the price from a recommended reputable workshop "Ah Heng" in Subang, I get it repaired first temporarily.

The 1st & 2nd Crack:

The 3rd crack (this one is real bad, almost as if it's breaking apart):

Close up:

My Repair History Episode:
My first repair visit was some exhaust shop in Sunway, I was quoted RM500++ for a set of Stainless Steel Exhaust System (excluding the Catalytic Converter). It was "really" cheap. During the first incident, I have also surveyed and remember one of our members, Dacmo (Donovan) have blog about a good workshop (Torque Gear) which does his RX7 and he also owns a 206. After checking with him, he suggested me to check with Everco in Sunway. Tough, in the end, I didn't take the time to go there.

My 2nd repair visit to "Ah Heng" in Subang, I was quoted around RM1500 for a set of Stainless Steel Exhaust System (excluding the Catalytic Converter). The price was quite surprising as it was triple the price of the previous quote I get, but the product/material quality and workmanship is very important in this case. Was thinking of checking out Jaafar and also Everco to get their quote, but in the end, also didn't took the time to do it.

Current Episode:
Cutting short again, basically in the end I went to Torque Gear in Sunway, which I found out was also belongs to/partner of "Ah Heng" in Subang. The reason I choose Sunway is because it is easier to access and less traffic congestion issue. Now here's the funny part: there was no Shop Name/Banner, when I reach, the shop hasn't open and I actually round a few times around the area looking for it. In case you're looking for it, it's just next to Beemerholics.

The boss name is Andrew, a friendly and nice chap. Now, here's the difference from the other 2 shop. Andrew checks through my BB Lion and explain some minor technical to me. Later, he went into his office, did some drawings and start explaining many things about exhaust modifications to me and also providing few options with different pricing for me to choose. The modding options can affect your powerband, whether you want to shift the powerband lower or higher or stock standard depending on individual preferences. To avoid me giving wrong explanation or confusing explanation, it's best for you to consult Mr. Andrew (no, not the blackdolphin) directly if you're interested in modding the exhaust system.

Basically, since I drive mostly in the city and I prefer to have more torque at lower rpm, I opt for the mod that is close to stock standard; Of course, this is in theory, the actual we will need to dyno it to find out. Due to my setup which the materials (pipe diameter) does not have local version and have to opt for imported product, it's the most expensive option of all. In total, it cost around RM1.5K (similar to what previously "Ah Heng" quoted). Damage to the pocket, but the workmanship is really good.

The Custom System Starts After The Catalytic Converter

The Cat (Meow):

Stock Peugeot 206 GTi Muffler:

NAKED!:

The Joint (Before touch-up):

The Sound:
I was also asked if I would like some "sound". As I don't really fancy these exhaust sound, especially inside the car when you're dragging your car in 1 gear higher, it's horrible, so I opt for the "quiet" version. I prefer engine sound, that's the real roar, especially when you install an open pod, that's the real nice and fierce roar. No offense but, exhaust sound sounded like 'fart' to me; It's different from engine sound and have this rhythm which sounds like 'fart', well after all, it's similar concept, the release of air (no pun intended).

I've sat in a friend's car with modded exhaust, it's really horrible experience. Funny thing is, he have also modded his sound system and installed head unit with video player. I can tell you that I'm sitting in front as passenger, and I can hardly hear the conversation from the movie, even talking and listening to one another is hard. It's worst when he tries to overtake a car, not to mention that his car is auto transmission, so imagine as he floor the accelerator and the "loudness" inside the car, it's like we're inside a subwoofer.
Nonetheless, it's not like I don't like the exhaust sound at all, I do like those that sounded "manly" and not over. I have heard few cars which have such nice sound, not necessarily from expensive cars, even many low end local cars have done good mod with nice deep "manly" sound.

Before the final process, Mr. Andrew asked me again whether I would like a little bit "sound", so I said, a little bit is OK, and also confirmed with him that it wouldn't be "loud" inside the BB Lion. Anyway, he told me not to worry as if I really don't like the sound, I can send it back and he will fix it up for me again.

Performance Issues Dilemma:
Actually, I'm also worried that the mod might alter the powerband NOT to my preference, as many of you may have notice many modded cars sounded really loud but performs badly, like what we always say "STILL THERE". They probably shifted the power band to the top end? Not sure. Anyway, Mr. Andrew also reassures me not to worry, as if I'm not satisfied with the setup, I can send it back and they can do adjustment to the current setup. This is a really good deal and service.

Custom Mod Info:
From the whole process, the hardest part which I can see is the muffler. Due to the placement of the muffler and the exhaust tip hole at the bumper, they need to divert the exhaust tip within a very small available space. I don't know how to explain this, but that's why they say a picture worth a thousand words.



Issue(s):
The only complain I have is... the exhaust tip is kind of too "OUT", it come out too much from the bumper, I actually prefer it inline with the bumper. I guess it's because when they were measuring and installing, they do it from the front to the back, thus in the end, the back have cramped space, and adjusting will need additional work.






Final Inspection:
Finally, it's done. Mr. Andrew did a final inspection and then gets into BB Lion, which is then being jack up for his workers to check for any possible leaks. Everything seems in order, and the sound seems quite OK to me, not too loud or slightly softer than what I expected. I was also informed that my Catalytic Converter is not in good condition. I've known this as it's been diagnose by Nasim-Peugeot Glenmarie Service Centre, but they told me that it is "wear and tear" items, thus there's no warranty.

Experience On Custom Exhaust System BB Lion:
When I first got into the exhaust modded BB Lion and as I drive it, immediately I felt a VERY big difference in the accelerator pedal.. It's so... erm... Light??? But as I drive, slowly it seems returns to normal and I can't tell the difference with before and after the mod anymore.

Power?:
As for power, honestly, I also can't tell any difference, maybe there's some improvements, maybe there is no improvements, or maybe. maybe. there is some drop in performance??? No idea, unless there is a dyno of before and after. Besides, I think a little increase or drop in performance is not really noticeable, MOREOVER, many factors can affect the current performance of the car even before modding. Even with stock, sometimes, you can feel the car is less powerful, probably due to tyre pressure, or some other reason, while sometimes, you feel the car's performance in tip top condition and just keep pushing. So, I don't really know if the mod have resulted in any changes in performance, probably it did shift the power-band slightly.
Sorry for those expecting some positive or accurate answer.

The one thing that is noticeable is... of course... the sound. Funny thing is, I notice it's slightly noisier around 3~3.5K rpm, higher rpm seems not as bad. After confirming with a passenger, seems it's not that bad as it weren't really noticeable unless asked to pay attention to the sound.
Standing outside BB Lion, the exhaust sound has deeper bass, which is OK, acceptable for me. Starting my BB Lion, sometimes it gives a nice deep bass sound, sometimes, it sounded very close to stock or normal, but if it's inside a closed environment, then it will sound better as the bass is deeper.

Overall, it will sound nice inside a closed environment (e.g. inside parking lot, car wash centre, etc). One thing weird that I notice, when driving in the rain, the exhaust sound goes deeper and more noticeable inside BB Lion. No idea why as of this writing.

Verdict:
Basically, from my personal experience, if you're looking for performance increase, I'm not sure if it's noticeable unless you're looking to shift your current power-band setup to a quite different setup?
Changing to a more free-flowing or less restriction muffler might possibly make some changes, but no idea what kind of changes.

If you're looking into modding your Exhaust System, I would advice you to go for Custom unless you can find a reputable brand which fits your car; And the workmanship is very important in this case.

Connects2 USB Interface & Aux Interface

My Connects2 USB Interface and Aux Interface ordered from ebay arrives on May 31st 2010. Initially wanted to wait for the weekend for the installation but my itchy heart and fingers can't wait until weekend and so I've installed it that night itself with the aid of torch lights. No chance to take the picture of the process and before installation already =P

When I first take out the Head Unit, I have no idea which connection to replace. The one provided by Connects2 was blue, but there was already blue connection? Thanks to intermilan for helping me out through "Call For Help", hehe. The blue connection is the wiring/connection for CD Changer, although there was no CD Changer, the wiring/connection is already there ready.

For the USB Interface, it was mentioned that if originally there was no CD Changer, you will need the Aux Interface to program the Head Unit. I don't get the real meaning at first and thought that the USB Interface will need to connect to the Head Unit through the Aux Interface, but after unpacking, the USB Interface and the Aux Interface have exactly the same connection, so the USB Interface will not be connecting to the Aux Interface.

So, firstly, I tried connecting the USB Interface directly to the Head Unit replacing the CD Changer connection, but to no avail. It didn't work.
Then I connect the Aux Interface and it works like a charm, that was really a happy moment =)

Next, I replace the Aux Interface with USB Interface... during connection, I heard a loud "dub", then I saw the MFD showing the CD Changer, but... there was no sound after I connect the LINE IN for AUX. I got worried, maybe the USB Interface is faultyt... I change to Radio, OMG, there's no sound either??? Then I remember the "dub" sound, possibly the speaker is damaged? Oh No....
Staying calm, I removed the USB Interface, and re-try the radio. Still no sound...
Thinking starting the car might be able to reset it. True enough, it works! Oh, that was a real relief.
Then I started thinking, possibly I should connect the USB Interface and start the car to reset the settings.
True enough, it works~ YAY~ =)
So, basically the Aux Interface is just to re-program the Head Unit if we don't have CD Changer.

Next problem is,... where to place this USB Interface. Thinking for quite some time, I decided to double tape it to my Glovebox. The idea isn't very good as the USB Interface device now have "sticky sticky" feels and substance if I remove it... but, after thinking and trying few ways, decided to follow the Nike slogan "JUST DO IT".

My USB Interface, comes with SD Card slot:

MFD, each CD Changer "directory" recommended to store up to maximum 99 songs.

If anybody have any information and pictures, please do share it to us!

Mmm.... the heart of the 206 RC...

Glow~ Glow~ SierraGlow~

Just the other day, I send my BB Lion for grooming. I've gotten lazy or can say much busier, plus it's really tough and takes a lot of time to maintain the car in Malaysian condition/weather. Anyway, to cut the story short, when it rains and thanks to the bridge construction in Klang, my BB Lion get dirty very fast and pretty bad (or should I say very bad). The tar sticks to my BB Lion and cleaning alone is very troublesome.

How it started:
Previously, I have viewed and *molested* Alan's 308 GT which have received SierraGlow treatment. If I'm not wrong, it's already more than a month after the treatment and the result is still fantastic, especially when you place your hand on the beast, and surprisingly, it's sooo smooth like just wax (totally don't match the character of the car, I mean, a beast with smooth skin? Meh. Just kidding Alan.)

After considering, and the price is also very reasonable or should I say cheap? Because if I were to send my BB Lion for detailing package by Meguiar's, it would cost me around the same price but the wax/sealant won't last long under our Malaysian weather/condition, possibly less than 2-3 months if expose the Lion outside under the hot sun and rain everyday, but SierraGlow claimed to last up to 5 years. So, I thought, why not spend the money on SierraGlow? Even if it doesn't last 5 years, I think it's still worth a try especially after *molesting* Alan's 308 GT and the result is surprising. If it were a normal detailing, I think possibly within weeks or even days, you won't get those smoothness like just after wax anymore. This smoothness is actually important and good because if there's any dirt or the infamous bird droppings, you'll be amazed how easy it is to remove it.

The Price:
As of January 2010: RM600
(10% discount for Autoworld Members)

Some information about SierraGlow:
The usual duration for the whole process would take around 5 to 6 hours, but it also depend on the car condition. I was told there was one car which is in very bad condition and they spend more than 10 hours for the whole process.

The difference of SierraGlow against other products of similar (as told by the boss, Mr Choong):
1. SierraGlow is non-organic.
2. SierraGlow is not Teflon Coating (Plastic); It's more like applying a Glass covering your car, instead of Plastic.
3. No need to send in for maintenance (unlike other which require you to send your car in for maintenance).
4. You can use any car wash shampoo to wash your car (unlike other which require you to buy their "special" shampoo).
5. No warranty certificate (this is not mentioned by Mr Choong tough, hehe; but I'm not sure about other product have these certificate or not). But Mr Choong said, if you have any problem, you can always go back and they can touch up for you (for FREE).

The Condition before Glowing:
Honestly speaking, my BB Lion has a lot of swirl marks and water marks, especially on the roof area, follow by the bonnet. So, they will need to remove this before they can apply the "treatment" to my BB Lion.

One Problem:
After Mr. Choong (the boss) inspected my car in detail, he notice my spoiler's paint is not done properly; Seems there is no clear coat or the clear coat is not done properly, so the paint condition is really bad and some area is cracking up. He said he will try to treat this area as much as possible.

Before It Begins:
Mr. Choong shares his knowledges and explains the disadvantages and problems of waxing and our weather condition which is true and you will understand and experience this if you have DIY these steps and also explains what happens when those dust stick to your car and when it rains.

Next, he also talk about his product and the difference with other similar product in the market.

He also shares about the basic washing process which is not mentioned by other/most detailing clinic, and the importance to clean off those dirt which accumulates on those edges or hard to reach areas.


The Process:
First, they will give the BB Lion a nice bath, SPA. They really clean it in detail, they will clean all those edges or hard to reach areas which usually is very dirty due to years of collection. They give the rims a nice SPA wash, cleaning it in detail, brushing it.

Cleaning the rims in detail.

Next, the paint cleaning process where they use the Clay bar to remove surface contaminants which usually not detectable by the naked eyes. After you wash and dry your car, you can use your hand to feel these contaminants which actually makes your polishing and waxing process difficult. After claying, you can feel the surface is sooo smooth like glass. You might notice the colours and surface are nicer too as you flow water through the surface. Once these surface is clean and smooth, you will notice it's very very easy to apply wax and also very easy to buff off.

The clay process - doing it in detail

Once the surface is clean of contaminants, BB Lion is put under 2 big yellow spot lights (wah, feel like a superstar already) which all the TRUTH will be revealed. The swirl marks, water marks, etc all is revealed clearly and the severity is inspected and treated accordingly through polishing process. Here, you can see they attention to detail they provide for each problem and they will try to remove or treat each part as much as possible.




After the polishing process, my BB Lion is given another SPA treatment (wash).


Next, it's the easiest part and also the main part, applying the treatment product from Japan; which is a type of sealant and they re-brand it locally as SierraGlow.
The sealant is applied and left dried (which only takes a short while).

The problematic spoiler - notice the middle part does not have clear coat
Many thanks to NZ Galaxy?


While awaiting the treatment or sealant application, another boss is doing some inspection.


And finally, he get his hands dirty to clean the lion logo on the rims.



After the treatment...

The POSE

Verdict?
Well, if you're expecting those deep wet look shine or those deep gloss colour from those wax detailing, sorry to say, you will not see it. It's a sealant after all and it was meant to last long (I hope).
I can't really give any comments at the moment on how good it is until probably a few car wash, exposure to sun and bad weather, etc.
I'll try to do a review follow-up after probably a few months. Hope it can last for at least 2-3 years, hopefully.

For now, all I can say is... Glow~ Glow~ SierraGlow~~~
