Please share your ideas was i engine running in normal condition, Im using Stage 1 ZA1JA00J 1.42B version. Fuel is Malaysia 97 grade. (I don't what grade of OCT / RON). small modify on the intake duct and stock everything else.
What i see from the graph. My AFR gone from as rich 12.17 to as Lean 20.33 AFR. Is this normal? |
AFR is fine. So are long term fuel trims. The 20.33:1 readings you get is during deceleration when the injectors shut off. That is normal. Once cruising under power, AFR will be around 14.5:1. And under WOT, you should see low 12s to high 11s.
