OK so over the past few days I have been having some stalling and starting issues with my car. I am running a Haltech VQ35DE Platinum PnP EMS and I put in one step colder Iridiums and now I am having some problems. The car will start out fine when it is cold but after it heats up to temp when I come to a stop the car will die no matter what I try to do with the throttle to keep it going. Then when it does die the car will not start until it cools down some, maybe about 50 degrees, after that it will start right up and then have the same problem again when it gets up to temp. I have tried everything I know of on the Haltech and I looked over my engine and everything seems to be in order. If anyone can help I would really appreciate it. I can send you the current map I am running so you can take a look over it.

My setup is a Fully Built Greddy TT kit. I can provide more information if needed.

 

Call haltech..

 

drill a 1/16th inch hole in the TB and raise the idle with a cipher or consult...


you need to play with the start fuel on the haltech too...

 

I already have a hole drilled in the throttle body, and I have been playing with the post-start enrichment.

 

Chris, check your email
I looked over the map you sent me. You had it configured to 0ms cranking injector time above 150degF coolant temp. I corrected this and sent it back to you a few minutes ago. You may still need to adjust it up/down a little bit to start your car perfectly, but it should start/run with the values I put in for you.

Let me know if you have any more questions.

 

Just curious how this would help? drilling that is?

 

allows more METERED air into the motor tricking the maf also. makes the ecu think the throttle is cracked ever so slightly effectively bumping the idle. cars tuned on a map sensor would not see the effect as much.

 

So what exactly are we drilling through? The body in front of the butterfly or behind?

 

its a half a$$ed ghetto fix. Dont do it...Unless you got some sick cams, you shouldnt need to drill anything.
