I have an S3 AMK and my MAF maximum value I can see is 170g/s. I don't know why I can't raise the boost the desired value of 1,1 bar at 6500 rpm.

Because the turbo is done, that's why!

Some news, no issue with this car...

I've test many other mod in the file, with stock tabgbts and lambts maxed at 0,77... But same issue, in long pull, when rev go above 6000tr afr drop down to 0,65 then rev stay and don't go up 6200tr...
I've test to decrease kfkhfm above 6000tr but same issue!

Maybe I does reduce krkte? But my long fuel trim is ok +3%

Another thing, for the low maf reading, with log voltage from maf, u max =4,51v. Regardless maf linearisation mlhfm, max maf is 240gr/s. However in the same log ma max is 185gr/s.
What can cause this trouble?

Thank for your help.



4.51V ~ 185g/s :



But your MAF seems to be the issue, it should read more with your actual boost.

After brand new maf installed, exactly same values... Maybe another problem on the car (sai, secondary air pump removed with resistor and no mod in software...

However this car has been sold since last year then no news or test in future...

Thanks french boy ;-)

I know few cars with similar problem  - all are after wideband conversion - has proper maf sensor (bosch brand new , compatible with ecu) and show too small maf readings...

maybe other guys know the solution where is the problem.
