I synced ignition today, repaired 1st coil's connector(positive wire was broken and caused erratic spark) and after playing with maps I was able to start the engine with acceptable idle.
It turns out that the base SR20DET map in Infinity's pack is way too lean (at least for SR20VET). I had to almost double VE cells in low MAP, low RPM area to idle engine smoothly and with targeted AFR.
