1.8T Ignition retard
« on: November 14, 2021, 10:47:12 AM »
Hello,
I have a problem with my a3 8l AUQ engine. Setup:
- K03s hybrid
- 380cc
- DP
- FMIC
- custom TIP
Cylinder head had a regeneration half year ago and problem still exist. Intake is hermetic.There are OIL CATCH TANK, new spark plugs PRF7Q, and new Beru ZSE051 coils with new wiring. Fuel pressure is correct. Compression on each cylinder is 11,5bar. Im sorry that logs are not from ME7Logger, I have an error ( code 4, i have to create new kline to ECU ), so I post vcds logs done on original ECU map.

There is ignition retard 7,5° on 4 cylinder. Isn't it too much for stock map? My purpose was getting around 240hp from this setup but ignition retards are making it impossible..

Retards are relative
They could appear when rl is lower than it actually is for example
Concentrate at ignition angle, its good to go

Ok, problem is solved. I've changed the MAF and ignition retard went to 0 on each cylinder. I didn't expect that cause my friend gave me his one to check and nothing changed. Weird...

That means old one was underreading and new one is reading correctly.
So now load is higher, fuel is richer and ignition is later as well.
