Mindfreakattack Posted January 17 Report Share Posted January 17 Good day Sirs, i have a Honda B16 NA engine. everytime i let off the gas pedal, AFR goes as rich as 9.5 before coming back to Idle AFR of 14.7 approximately. The duration it stays on rich AFR before returning to normal coincides with the duration delay i set for Fuel overrun fuel cut (Tq reduction / introduction time), which is currently set to 2seconds. While i understood having a rich AFR for a split second doesnt hurt, i am curious to see if theres any adjustability for this part. *I tuned it for 2 second delay for torque reduction because somehow it gave me better drivabilty when shifting gear and decelerating. Tried reducing to 1 second or zero delay, the car was jerky whenever throttle was let off. Any info would be very much appreciated Have a great day guys!! 16Jan23 updated fuel.pclr drivability check log.llg Quote Link to comment Share on other sites More sharing options...
