Thread: Avenir Idling issues = Pain in the butt

Okay thanks Guys

Also if a the injector size on the ecu is bigger (i.e My injector is 370cc and the ecu's is 550cc) but everything else on it is compatible with the swap will that have any major affects?

Yes, you will run really lean and probably blow up the engine

I'd just upgrade to the 555cc's so you won't have to upgrade in the future.

I got the right ecu this time and it helped the idle issue a little bit but now when i have the MAF plugged in the car barely starts and immediately dies. I've unplugged it and it idles between 1.5k-2krpm.

Did you correct the MAF location ???

BOV Re-Circulated ???

Turbo piping or Vac leaks ???

Does it idle high at startup only or all the time once it has reached normal operating temp ???

The MAF is between air filter and turbo compressor.
I followed the jgy bov diagram.
It sounds like theres a leak but i cant locate it.
both and itll do the rough high idle continuously.

I dont think a knock sensor would cause this would it?

Can you tell us what CEL codes it has? Also, are you sure the ECU is exactly the same as your current setup? Everything matches? Compression/injectors/maf?

P0325 & P0335
Yes the ECU is setup to match the current setup.
I started it this morning and it idled at 2.5k rpm for about 20secs then it started fluctuating roughly and sounded like it was gasping for air lol And the turbo started to smoke again.

Have you ever been able to resolve this? My engine is behaving the same, except I have a JWT ecu programmed for a Z32 maf and 370cc injectors.

Let me know if you found any solutions
