I finaly finished my upgrade on my 2003 usdm e8. the setup is:

2.3 stroker
1000cc rc injectors
cosworth 272/272 cams
1mm oversized valves
supertech springs
hks camgears
gt3071r turbo kit
alloy fuel rail
255 walbro pump
aem fuel pressure regulator
hardpipe kit
3" turbo back withou cat
standalone engine management

The problem is the bad idle. i can set the idle only to 1200rpm. I think its possible to make good idle with these setup. My current cam setup is 0/0.
Any idea for this?

What exactly is it doin? Idle fluctuating up and down, starting and dying etc.?

check the B.I.S.S.
And you might have increased the desired idle rpm a bit too much. Try ~ 1100
what is your idle timing @ in your timing map? Might wanna try advancing it a bit. between 7-10* on pump.
Whats your scaling and latency for the inj.? fuel trims?

Im not familiar w/ the standalone, but maybe there some map in there that needs attention?.?.

if it's idling too high, you can lower the timing in that cell too.

i.e. 800rpm = 15deg
1200rpm = 5deg

so if the RPM is too high, the low timing will lower it back down.

the idle is stays arount 1200rpm. its smooth at that rpm , under that its lifting 200-300rpm. if its goes under 700, the engine is stops. i tryed to rich it to 12.5afr, lean it to 15,5afr. its same thing. tryed to change the ignition timing betveen 2-18deg. nothing changed.
