Lightened flywheel the problem?

[GsxEcutioner]

So I replaced the flywheel with a Fidanza Lightened flywheel, Put the new trans in, everything is hooked back up but now I start the car, and it idles for a few seconds and bogs/dies out. is it because of the flywheel or what else can it be?

could be, the 9lbs is light.. might want to bring the timing up to around 19* at idle..that's whre mines at with the same flywheel

If i remember right i had to slightly bump up my idle with my fidanza, other then that I didn't have any problems with it.

So timing can cause stalling on cold start ups??

This is all on initial cold start up. I can't even get a log because it doesnt stay on.

Maf connector was dirty, and I was running my old tune in Link....Reset the ecu and it ran fine. Thanks

What RPM is your car set to idle at?

I'm kinda of confuse. How did resetting your ecu help??? Curious!

Just unplug the battery for 5-10min... Then it should be back to stock settings.

If your using dsmlink.

Yea, you'll have to bump the idle a little bit to compensate for the lower inertia. I even had to do this with the ACT streetlight one... so yours is even lighter!

IIRC, you unplug the coolant temp sensor, which should set the computer into a sort-of "default" mode so that it won't fight you as you adjust the BISS. Stock idle should be around 800rpm, I bumped mine to 900-1000 and it seemed to be ok with that.

edit: nevermind.. missed the post that said he figured it out.

+1 on bumping up the idle a little bit. that fixed my problem 100% now and ive had the same flywheel as you for several years now. good luck

Idle is now 950, grounded it by link and adjusted. My old tune had something to do with the way it ran and I have no idea why. I reset everything in link and started over and it's fine now.
