K20A w/ Injector Dynamics 1000cc- Slight lean A/R 20% to 50% throttle

Post by csantz_89 »

Hello,

Upgraded injectors ID1000cc and dead time calibration following KPro look up feature. The engine seems to idle correctly and accelerates in a linear fashion. Although, the engine goes through a lean A/R from approximately 20% to 50% throttle. The A/R during this period was monitored at ranges of 14.8 to 14.98. If someone knows the fix to the lean spike, could you please assist in the matter.

It needs to be properly tuned on the dyno with the new injectors to make sure the AF ratio is safe everywhere.
