Okay, Here's the low down. Still new to this level of engine modification. I'm a paint and body guy by trade. So I have a 2000 LS running a GT30, 8psi, 460cc injectors, greddy emanage ultimate. Still have the factory FPR. My AFR stays between 11-13. Problem I'm having is that once the car hit operating temp, shutting it down means waiting 10-15min before it will restart.

I've tried searching thru the site to see if this issue has already been covered but only stumbling across stuff that is over my head. So I may have read the answer and didn't realize it.

Who thinks they've got the answer in kindergarten terms?

11-13 in what? cruise or boost?

Wait for it to warm up so you can duplicate the situation. Take an ice cube and toss in on top of the air temp sensor for like a minute or two then try to start it right after. I dont know Emanage but i'd assume it has a hot start settings of some kind. Cranking settings per degree per the engine temp.

Small detail I forgot to add that might help. Only started doing this since I installed the 460cc's.

11:1-13:1 AFR. Under boost.

So did you tune everything? Personally I have the feeling it's a hot start tunnng issue.

I just did a novice street tune on it. Mainly toying with the fuel values and watching my wideband. Always erroring towards rich. I say it's between 11:1-13:1 but it only hits the 13's under full boost. So would a hot start issue manifest by simply swapping the injectors and adjusting the fuel values?

What did you change on your tuning after you added the injectors, was it running good on your stock injectors with the Emanage?

Tune for 14.7 up to 70-80kpa then start going to 14afr going to 13 at 100kpa and then 12afr in boost.

I just played with the fuel map. The injectors were flooding it to the point it would die.
