Prime pulse and cranking cold start issue on Subaru MY10 EJ25. 1200 CC injectors

Hi everybody,Michele from Belgium.

I'm using an Haltech PNP 2500 Elite ecu Map based.The car run like a charm on boost,transient,etc.

I'm stuggling with Prime pulse and cranking cold start issue on my Subaru impreza MY10 EJ25. with 1200 CC injectors on E85.

At low Temp (0° cent.) the car won't start at the first attempt,I always have to try almost 3 times before the engine start.

The engine is tuned :pistons,injectors,GTX 3076 GEN2,3" exhaust,1200 CC bosch inj, etc.....

Can someone help me with the starting cold start table (prime pulse,cranking,Ign start angle,...)and perhaps some advice regarding the main setup,Ve table or something else that I miss ?

Thanks in advance.

Michele.
