Thanks again Mituc

Thanks for your response, mituc! I forgot to mention that I'm running a stock exhaust with straight pipes (cats and resonators removed). I also have a 3.5 bar MAP sensor (Bosch 0 281 002 456) with the corresponding calibration. I've attached the tune file and 2 logs: one of slow city driving and on...

Love your work mate, even if its picking apart my tune. I've added comments below You should NOT use min AFR set to 11.02 when you are targeting lower than that in several parts of your tune, and also put limits on the ECU logic on how to handle knock if it comes down to that. I can not see where I ...

I've changed to your MAF calibration. The first few cells with values in them that were significantly different to the stock calibration I wasn't concerned about as the voltages are such low values they are never used anyway.

Back from holidays . Attached is my current tune

Thanks Mituc. I'm away on holiday for two weeks so I'll have to wait until I get home.

I've downloaded and compared again and I'm not finding any mistakes in my original comparison.

Hi Mituc,

I compared the first few cells and saw up to 2000% differences so thought something was wrong. After looking at it closer I can see most are 14-15% greater across the board. But big differences in the first few. Do you know why?

i've attached an excel screenshot comparing them

I do have an aftermarket BOV. Turbosmart Kompact Unit.
I could check for boost leaks

I'll lower the boost slightly and see if I still get ignition retard.

Thanks again Mituc.

Summary of Changes to the Tune Copy of 93US/98EU Octane Stage 2 CPE CAI + Corksport Race Pipe - Stock MAF Calibration - Reduced Max Boost before throttle plate reduction to 240kpa (20psi) - Load Table - Amended from 62.5% T...
