I just got this Demon 2 and have it working pretty good so for.Now i am putting it with my H23 v-tec with a crower cam and reworked intake manifold ,70mm throttle body,and 3"cold air intake.Now when I start the car it goes right to 4000 rpm.I tried to enrich it with the fuel map but it runs too rich to get the idle down. I noticed on your soft ware in the injector calibration you have something called over all fuel trim. Is this what I need to use the rich this thing up?

You posted in the TunerView RD 2 section, and this doesn't seem related.

Being a little rich or lean can't cause an engine to rev to 4000 rpm. Fix that issue first.

Overall trim can trim fuel either direction, as stated in the help.
