Goes lean over 7500rpm (INJ decreases)
Posted: Sat Mar 24, 2018 1:31 am
Hi,
could you please help me with some issue.
K20A2 with TodaA3 cams, stock 310injectors, fuel press 47psi, porting head with increased compression ratio.
Over 7500rpm at full throttle engine goes lean from ~AFR13 to AFR14 but I'm increasing fuel amount a lot in the calibration file. In the log file I can see that INJ duration goes down at 7500rpm from 16ms to 14ms at 8600rpm. Why is that happening?
WOT compensation fixed at lambda 0.85, but I try to lower lambda in WOT compensation tables but without any results.
I have already replaced fuel pump and fuel filter.
Please help, thanks in advance.
