has anyone ever tuned one of these? My data logs are not matching what I am commanding in the ECU. I am a little confused at the logic. I changed my equivalence ratio yet there was no change in my datalog my commanded equivalence ratio got progressively richer with RPM. Also my fuel trims are still active in open loop. I wouldn’t be able to post a data log or a tune file until tomorrow but I’m hoping somebody can chime in that has worked with these ECUs
It's not an ECU that we've dealt with sorry. While the PE EQ Ratio table is a key driver for the open loop AFR targets, there are also a range of adder or multiplier tables that affect the final result too so I'm wondering if that's what is going on here. I'd suggest posting the calibration and a log and we may be able to help more.
