So after having my car retuned on crome it is having a quirky start up issue.

It is an LS with rc750's @ 12 ohms and the peakboost kit. I have an MSD external coil and a completely stock longblock.

When I say cold I don't mean below zero. Any FIRST START of the day the car will turn on and immediately shut off. It won't even try to keep running. If I do it and give it gas for 10-20 seconds it misfires like crazy and then holds and idle and drives like nothing ever happened.

When it does start and stay running the idle stays at 850 where I have it set. For some reason my idle never goes above that even when it's chillier out. No CEL's. Fully converted to OBD1.

Any input on this?

Thanks!

 

Anybody? Runs like **** in the morning. The colder it gets the worse it is.

 

Get up with your tuner.

 

Whats the AFR during the condition? Im willing to bet if the ECT vs Idle table isnt bumping up the idle nor is the ECT vs fuel table adding any fuel for warm up either...

 

Most likely its adding too MUCH fuel if the stock settings haven't been changed. The program still treats the "advanced" tables as factory injectors, hence dumping too much fuel. Sounds like your "tuner" is a joke.

 

I can send over the .bin via email if anybody wants to look it over? PM me an email.

Any help would be appreciated. My tuner is a good friend and he lives 2.5 hours away. Plus even if i drove to him for him to see the conditions the car would have to sit and I don't have time for slumber parties lol.
