Re: P0101 after larger throttle body install
Didn't get freeze frame data yet to post but I will say driving it so far doesn't seem to run 100% correctly after this change to both the upper and lower MAF thresholds.

Re: P0101 after larger throttle body install
Changed those values by 10%. Same code returned. I'll get the freeze frame again but when I checked it on a cheap scanner showed 23 g/s MAF value at 2100 rpm.

Re: P0101 after larger throttle body install
I see MAF flow delta absolute high and low thresholds which I think is what you are referring to. They are .7936 and -.7936. do you have a recommendation on how far to bump those? .80 and .-80?

Re: P0101 after larger throttle body install
I'm not positive but I'd think if the fuel trims were the issue it would be throwing a fuel code. From what I have researched the p0101 can be for 10% variance in expected mass air flow values. Is that correct?

Re: P0101 after larger throttle body install
I was able to get the freezeframe from another scanner. VersaTune does not have the ability to see it that I could find.

Re: P0101 after larger throttle body install
VersaTune does not have the dtc freeze frame option unfortunately (At least I could locate). I can see if I can log with another tool. I'll get that and post it. Hopefully in the next few days possibly. Thanks again for helping take a look.

Re: P0101 after larger throttle body install
Those logs were split from one large one headers should all be the same and line up. This log was taken with the DTC disabled. I can get another log with the light on and dump one here as well if that would help. I agree the throttle body shouldnt have really impacts the MAF

Re: P0101 after larger throttle body install
Here is a driving log and the tune file that is on the car. Sorry for such a late response and thanks for taking a look.

P0101 after larger throttle body install
Anyone work through rescaling MAF calibration tables to correct a p0101? I installed the Bosch 68mm throttle body and am using the crackle pop tune. Car doesn't seem to really care about the code. I have reflashed the tune disabling the DTC for this code to collect data and started to attempt a resc...
