85mm truck maf I have an 85mm truck maf that was installed with intake and cam.
As per the instructions on starting to tune in HP tuners I set the maf failure rate to 0. I get no code and when I scan I am still getting a signal from the maf. I have tried disconnecting the maf under hood but the car will only idle but not run.
Anyone else have this happen.

At a MAF Fail frequency of 0, you are still going to get a signal from the maf because the VCM can read it. But not a problem because your VCM should go to SD mode automatically. Sometimes it takes a while for the check engine light to appear. On my vette I went 2 times with the car on the road and the Check engine light never came on when I was in SD mode, but I could tell just by looking at the LTFT histogram and just by feeling the throttle response that I was in SD mode.
