Hey guys, I need some help I have spent all weekend on this job finally got the car ready to fire this morning. And it wont stay idling, and dies at any attempt to give it fuel.
Heres what it is
97 spyder gs
Wired in 98 gst ecu, with ign wire ran to pin 82 and knock sensor wire ran to pin 78,
Crank sensor elimination using adjustable 1g cas
1g tb with 2g tps
The car will not start and qhen it does it runs rough as hell and wont lwt me give it fuel at all
Heres the weird part
I take my 97 gs ecu plug it in and it works great until it hits boost then it shuts fuel off
What i have tried
Swapping firing order to 2341 along with swapping ecu injector pins
New tps
A different known working 2gt ecu
It jas me baffled because i dont know what is going on to allow it to not run with turbo ecu but run with gs ecu
I also had to rewire the 4g63t iac because mine had the flat six pin

Any help would be great
