I haven't dug into the COS's yet. I'm wondering how I can go about fixing the following problem:
Fueling is dialed in well for when IAT is 70~90*F. Once it gets up into the 100's and above, it starts to lean out (even more so in the low airflow scenarios). I don't know if it's something I can fix with the Charge Temp table or not.
Anyone else tackled this problem? The last resort is to buy two NBO2 sensors and let the fuel trims take over and add fuel in. But, I think that's about where I'm at.
