I've noticed this too... Mind sharing the actual current MAF scaling for the Primo intake? I have your old and original scaling you shared with me a few weeks ago and my car ended up being no where near close using it so I continued to make changes manually.

Just curious what you ended up with. I had my both idle and cruise trims literally sitting +/- 0.38 then a couple days later it was floating between -3% and -4%. while the temperatures were colder...? I've left it as it sits right now since it within +/- 5% but I have a feeling once it gets much colder it will drift of much further.

Has anyone found the table for air temp correction?

 

We're still on the same one I gave you a few weeks ago (1.3x transitioning up to 1.5x).

With the factory air temperature compensation, the fuel trims will drift with air temperature change, especially with e85. Same thing happens with Evo 8/9. I typically deal with it by altering the injector scaling, but the more proper way to deal with it is to fix the air temperature compensation. We can do that on the 8/9. I can't recall right now if that table is available in ECUFlash for the Evo 10. Its definitely not there for the AP.

 

I have similar issues with HKS intake and I was looking for a solution. Can you share the table def for air temp correction ?

 

I just finished taking a look for the table. Wasn't able to find it in the time I had available this evening.

 

Are you using the new BETA version of ATR?
