I cannot get my maf histogram to read anthing but zero. Can someone give me some help on what to fix. I have tried everything I could find on that subject and it still just reads zero. Thank fo any help.

Are you in closed loop?

Normally the MAF histogram is reading out the STFT % for the individual MAF cells, which only happens in during closed loop.
It could be that your histogram isn't looking at the right sensor, or you have the filter set wrong, or there is a syntax issue with your scanner configuration... lots of possibilities.

It might be best to post your tune and scanner config on the HPTuners forum so others can take a look at your actual setup and point you in the right direction

Thanks for the reply. What about running a LQ4 maf sensor. Would that make it not read.
