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.

We usually reply within 12hrs (often sooner)
