G4 Storm; engine stalls at cold starts

[Kerem Erdag]

First of all, thanks to pc link quick tune function; all fuel map was finely tuned in 6 dyno runs and some interpolations. with perfect results.

Engine is BMW M30B35 turbo with compression lowered from 9:1 to 8:1 with 380cc injectors, stock 3 wire bosch ICV.

Now my only remaining problem is engine stalling on overnight cold starts. it starts perfectly, rpm increases upto 1400, after 3 seconds suddenly it goes below target idle rpm and 8 out of 10 starts result with a stall.

What I feel is after startup step duration completes, it gows down to idle base position directly without any steps. 

Is there anyway to make this decrease in steps? If yes, how? If no, what is the solution? increasing antistall gain for low ect?

 

Thanks for the help in advance.
