just installed a link that i took off another car. my car is a stock 93 and i have loaded the NA OEM base map to it. Map is reading correctly and so is the intake air temp. The engine fires right up to about 1500-2k ropm and sounds good. Stays that way for about 1 second then it shuts off. will do this no matter if i hold the throttle open or not. When i crack the throttle it does get as high as 3k rpm before shutting down. I also made sure the sequential injection parameter was turned off. Like i said, bone stock car. nothing but the basic link wiring changes were done. Anyone have thoughts on this? I feel it is in a parameter that i am missing but not 100% sure.

 

Few things I'd check
- Master fuel: make sure it's at 100
- Cstart: whatever that is, bump it up
Sounds like your injector prime is working since the car is firing on the first try. Also take a look at this thread:

Fuel pump isn't running. I bet the Wideband O2 mod was done to the ecu so the trace between 2p and 2r is cut. This drives the fuel pump pnce the car is running.

Pull be board out and check if the trace for the wideband was cut, if so, you will need to move the wire as per the wideband mod instructions to keep it running.
