I did a search and didn't get the info i was looking for so here goes. Im finally getting my car back today and my mechanic tells me a may have some annoyance in the fist little while with my car. He says because my flywheel is lightened (fidanza 9lbs.) and my injectors being so big (720cc) that when my car is reved up from idle it falls back to 1000rpm and then drops out and dies??? I've got hondata stage 2b with a program for the meantime im thinking it may be that??

Need your help guys. Basically what im wondering is if this sounds familiar or what you guys might think it is?

any help is great.

 

Its the tuning, not the flywheel. The 9lb flywheel still carries enough rotational inertia to keep the car idling just fine. You'll find the overall ability of the engine to rev up and down is quicker with the flywheel, so the drop in rpms is fairly normal. The engine dying upon the rpms dropping to the 700-800 rpm range (idle) is not. It sounds like injectors were not sized properly in the maps.

 

The flywheel can cause this, but you should be able to work it out in the tuning. You may need to turn up the idle just a hair as well.
