FG6 Turbo timing / boost compensation / Idle in park netural lean
Hey guys,
Just getting my head around some tuning of my FG turbo and have a few questions with small issues im running into.
1/ AFR's are a little rich on full boost (approx 11:1 @ 16psi) but pretty good otherwise cruising
2/ AFR's great at idle in drive but netural and park sees AFRs shoot up to 17:1 and stumbles
3/ Logging I find that as soon as I hit 6-7psi boost timing falls away and I cant change it. Is there a boost compensation table or is this torque management that's doing this as my spark table commands much more timing.
Only mods are 1000cc bosch injectors, bigger fuel pump with 4mm hole drilled in bottom pipe as recommended and battery re location with big air pod in box and removed cat converter. I know the high and low fuel rates are just rough but I experimented till I got some great idle and smooth running as well as good, if not a little rich AFRs through rev range and boost curve
Any advice would be great thanks
