How To Tune Transient in Toyota 2UZ-FE using BitEdit

Hi,

do you have any experience on using BitEdit to tune transient enrichment - I have a very lean burn back-fire to intake on acceleration, which I suspect coming from the Transient Enrichment on kick-down condition. looking at the data log, the AFR rose to 1.23 (lambda) when the engine kick-down. The engine has custom injectors (450cc increase from 288cc), a big 2650cc TVS supercharger and a custom duration street cam? pulling my hair trying to figure out the lean-burn back-fire from the kick-down

Hello,

Did you figure out how to solve it?

there is one table which could help you with lean afr at kick down.
