Eric Godden Posted January 6, 2010 Report Share Posted January 6, 2010 I installed my G4 extreme not to long ago and have been slowly tuning the fuel map in my free time. One issue I have run into is that when the car is in say 4th gear the fueling is spot on (14.7 cruise etc), however when in 1st and 2nd gear the afrs will be much leaner than they should. Say 16afr etc. This occurs most times during clutch release for accelerating from a stop and also when moving slowly in say those gears. I haven't gotten into doing any power runs all loads are below 0MGP. If I tune the main fuel map for proper AFRs in the lower gears , my cruise afr is now 14afr. I have messed with the accel enrichment table but this seemed to have little or no affect as it runs lean at constant throttle openings not tip-in. Has anyone else experienced this problem and what was your solution? Thanks Quote Link to comment Share on other sites More sharing options...
