Had to jump my car with one of my trucks. She started right up as usual. Got out and as soon as i disconected the negative jumper cable she flatlined. No studer or burp. Just shut down. Turns out some thing is dumping fuel into all cylinders. This is ONLY when the Utec is in the mix. when out, the ecu (streettuner reflashed) runs the car fine. She starts right up and idles perfect.
Just wondering if anyone had had a similar issue ever with a utec.

The maps came off the utec and im gona try a new one tomorrow. Il post. Hoping it was the injector drivers but maybe the GM maf? It has to be some thing the utec is using that the ecu does not, right?

2004 wrx with utec over a streettuner reflash. Using SD (speed density/blowthru) and GM map sens.

Thanks.
