Excellent job! :thumbup:

 

Good stuff man! This will def benefit the community -

 

after a few weeks car is runing great and haven't had any misfire problems so overall this was a great mod in my opinion

 

What ground issues did you have? How did you resolve them?

 

Mostly on my part, 1st was the ground on the valve cover, I had powdercoated my vc and i guess i didn't sand enough for it to get a good ground.

2nd i noticed that the harness i got had the ground wires hooked together, 1 for the vc and the other i grounded to the ICM ground. The one i used for the ICM ground was merged to 2 wires instead of 1 so i used the larger of the 2 wires and soldered that to the ICM ground and the smaller one i grounded to the back of the vc

After i did that it stopped my misfire issue i was having

 

In what way does the car perform better?

What the pros and cons of this conversion?

 

Pros

no more ICM lol
Better Spark
Better Accel

Cons

so far none atm

 

well before i did this mod, i can tell you the car itself ran ok but you can tell it didn't have any acceleration, i had even changed the plugs prior to the swap and nothing. After the conversion i did notice the car had more pep, when i gave it gas it actually goes. It is hard to explain but i did feel a big difference from before and after.

 

I just have a hard time believing it, if you had physical proof in logs or something I'd be more inclined to do this mod.

 

you don't have to do this mod, the reason i did it was because i was tired of buying ICM's, paying for tow trucks,etc. I took a chance in doing it because i also had a long term goal for the car and looked at this as a plus. I made this write up to help anyone else that considered doing it and make it easier to do.

 

Great work, especially the harness heat shield.

 

Thanks. After I posted I did realize that the improved grounds were already part of your DIY. Looks likei will do this sooner rather than later.

 

I think another way to go here would be to do a relocation of the ICM... Where it sits from the factory, it's bound to get heat soaked and will cause your issues. Put it somewhere cooler, and I can almost promise it'd be less prone to problems down the road.

 

Where it sits from the factory, it's bound to get heat soaked

From the factory, the ICM is bolted to a heat sink with thermal conductive paste like the CPU in a computer uses. The heat sink is embedded in the top of the airbox so the bottom of the sink (thick fins) is exposed to the constant flow of cold intake air being breathed in by the engine. Not really a bad placement.

The AEB does suffer from failing ICM's, but the coilpacks are rock solid and last. In later designs they deleted the stand-alone ICM and incorporated its function into the individual coilpacks and guess what... the coilpacks became the failure point. I would guess the coilpacks are exposed to more heat than the ICM, but they may have accounted for this when they designed the new style coils. I don't know.

The newer style ignition system is said to have a higher output. I don't have any specs so I can't confirm this. I do know they decreased the spark gap from .035~.043 on the AEB to a max of .032 on the ATW, AUG and AWM.

 

I too have heard that the AEB style ignition puts out a weaker spark than the later system, hence my desire to change. Any definitive info??

 

I forgot to say, the valve cover powder coat and new coil cover looks Awesome!:thumbup:

 

Thanks alot

 

That is a good looking valve cover....


But I have a awm so no icm for me. However I did have my coil packs replaced at 68k miles free of charge thanks to the vw recall . They should however get hot there due to it being bolted to the head. More so on turbo models. But the icm probably should have been put between the firewalls from the factory. A lot less heat there.

Here's a DIY I made on audizine

Hi, I'm from Argentina ... sorry for my English tarzanico .. (google?‍♂ translator). The modification was really spectacular !! Regarding the improvement, the mere fact that you have a better spark gives more power, since it performs a better combustion of the fuel entering the cylinder. I loved the aesthetic finish the valve cover both the paint and the coil cover. I have a passat b5 year 2000 engine 1.8t APU engine which has the icm ... will the wiring be the same? I would think so, but maybe someone has the certainty and would be very grateful ... I am arming it with a turbine exchange for a k16 and some more evils ... I would be ideal to improve the quality of the spark for better performance.
