With cooler weather my fuel trims have returned to a more reasonable level. I consistantly get LTFTs of around +5 to +8. We had a 102F day and my IATs would sit at 135. Fuel trims then where aproaching +20! I also notice that these trims are somewhat carried over to open loop as my AFRs are dipping down to 10.8 at around 4K. I'm pretty sure if I dissconnected my battery and reset my LTFTs to zero that my open loop AFRs would lean out to the 12.5 I want and had for a while.

I ordered an AFPR, plan on increasing pressure to get trims closer to zero then re-tune with EC.
