hey guys im having a cold start issue, this is a fully built h23a trying for first startup. i have used most of this map on the car last year on a stock motor.
i just modified it for a few things. here are a few details. full e85 , added coil pack retrofit from hondata (i am 100% sure im getting spark) plugs are factory gap after replacing them from .017 (no difference) ive messed with the fuel cranking ms and no change. here is a datalog and calibration. please help... oh and i smell fuel on the plugs too. temp in garage is around 45 degrees.

Re: cold start problem
What injectors, fuel pressure, map sensor? Usually have to decrease the post start rate of decay to get it to start and run for E85 under 50 degrees.

Re: cold start problem
injector size is set to 2470, make sure dead times are correct for 50 psi of fuel pressure. Make 20% changes in overall fuel trim until it starts. try giving it throttle while starting. If it needs throttle it's too rich.
