see what it looks like idle to 4000 rpm log long term &short term fuel trim, rpm, load ,mafv, throttle, AFR, commanded AFR
see if the ltft are less than 10% and that the commanded AFR and measured AFR follow each other under load. If your ltft is over 10% under load and the commanded AFR and measured afr are way off then something is wrong. If maf scaling has been done correctly ltft should be less than 5% or possibly less than 3% under load.
did the cel come back after ecu reset
check for air leaks on intake and that maf sensor seated correctly and is clean, especially if you run an oiled filter
Do you have ecutek map switching ? are you on correct map, you did not switch back to stock map or something ?
