Other than K, latency, lowering top right area of timing map, and flatten fuel maps what areas did you have to adjust to get yours running right af...

Re: Start tuning SR20DET

th regards to tuning with larger cams like you have is there anything specific you needed to initially do to get AFR's near 14.7 at idle? Do I still try to keep near stock K's after MAFS and injector sizing or is there something else I should do too with bigger cams? Just trying to get it to idle w...

As You can see timing is fluctuating between 7-15 degs, TP is 11. idle_low_afr.png Idle is correct (idle table below): target_idle.png I assume that problem is TPmin table (table below), because...

This is how look AFR avarage trace for 2 log sessions (about 4-5 min of constant ride to my work): trace_avg_afr_1.png trace_...

Re: Start tuning SR20DET

Extra question to my timing map:
Is 15' from 4.7k to cutoff (7.6k) is correct for my setup? When I had 16' I have started to hear knock.

Re: cold warm up

the timing spikes up to 110 degrees and stalls the car,
Maybe your CAS is broken? 110 of timing is very strange.
