I'd change it by 10 to 15%..

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? That is a possible reason for the code to be set. Try adjusting the MAF minimum/maximum ...

Tune in Lambda... tell the ECU what fuel you are using under fuel specific gravity.. Use the built in calculator to figure out what value you use... Your ECU is tuned from the manufacture using Lambda. Log in Lambda... Stop living 20 years ago thinking in AFR's... Lambda doesn't care what fuel you a...

When the code sets you can still look up Freeze frame data. It's a snap shot taken by the ecu when the code gets set. So long as you haven't cleared the code that info will still be available from the last time it set. hopefully versatuner can look it up, otherwise any cheap scan tool can look it up.

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 If the dtc or mil light...

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. Logs 2 and 3 are missing the headers. The first log has short term and long term fuel trims from what I see... You can remove Desired EQ/AFR. The pid doesn't work for some reason...

Your MAF signal is going nuts in different areas. Does the CPE intake have an air straighter close to the MAF sensor?

Hit the log button once the motor is warmed up and go for a little drive. Log the whole drive. You want different throttle positions, try and stretch out the light throttle rpms.. Do a couple WOT runs if things feel safe.

Posting your tune and some logs would be helpful

If you are starting from scratch that means you have your stock tune from the ECU to work from. Can you post it.
