So the MAF calibration logs look good. I'm a little concerned about the high fuel trims in the first part of the MAF curve, up until like 2 Volts or so when the LTFTs are 16-17% which is high, but that is idle/low RPM air flow so at least for now it should not be a concern.
Above like 2.5V the MAF calibration is spot on.
Either way just to be sure take a look under the hood and make sure there is no leak between the MAF and turbo. It may be a small leak that closes when the vacuum in the intake increases (turbo spinning faster), therefore sometimes just repositioning all the hoses and re-tightening all the clamps may help.

Re: New User
I will check for air leaks.
What's is your opinion for the knock retard in one log?

Re: New User
There is absolutely no knock retard in your logs. You should try the 98RON tune if right now you have 98-100RON gas in the tank.
Low timing + high octane gas means high exhaust temperatures and over time the exhaust valve seals will cook and there's going to be also a lot of soot coming out of the engine, and part of it will come back into the intake via the EGR.

Re: New User
I will flash a new tune with 98 base and maf calibration for Cobb intake . I will also check for leaks.
Which dashboard preset is StockCar Monitoring 2?

Re: New User
Sorry mituc.
My mistake.
I had not downloaded the preset when I made the wot runs and I realized it now.
Do you want to do wot with this preset?
I would like also to tell me your opinion.
When I finished my new tune, with your maf calibration for Cobb intake and the Base 93US/98EU, I tried to make a comparison between this 2 tunes.
I saw that there are big differences at the Absolut Limits/Load Targeting Tables.
for example:
Base 91US/95EU / Base 95US/98EU
Closed Loop Load Limit 1,2,3 2,5 / 3
Load Limit Force Spark Retard 2,5 / 3
Neutral/Reverse Max Load High BAT 1,693 / 3
Neutral/Reverse Max Load Low BAT 1,693 / 3
Operating Load Limit 1 0,803-0,856-0,911 and then 2,5 / 3 at all RPM
Operating Load Limit 2 0.803-0,883-1.019 and then 2.5 / 3 at all RPM
Requested Load Limit Overall 2 / 3
Requested Load Limit RPM 2 / 3
I found it weird.
Is this ok?

Re: New User
You will never reach those values anyway and they are set for the logic of the tune, not for its functionality on the car. In your case it they are set at 2.2, 2.5, 2.7, 3, 3.5 or 4 makes absolutely no difference.

Re: New User
So I can change this values from 95 base to 98 base without problem or affect the operation of the engine.
Thank you mituc.

Re: New User
If you really want that... it's not necessary but changing them will not affect the logic of the tune or the way it performs.mteogr wrote:So I can change this values from 95 base to 98 base without problem or affect the operation of the engine.
