I just thought it would be cool if anyone else out there has an xfi computer to post there tunes in here. I dont know much about tuning, but i messed with mine until I got it running good. Then they had an update to the firmware, and added a couple new tables. I reflashed the computer and modified a bunch of tables that it says to do, but now it dies out if i dont give it a little pedal when its cold. Its gotta either be fuel enrichment in afterstart, or iac vs cts. Just havent had time to mess with it, and after 30 sec its fine. Right now the motor is stock, with a fast 90/90, 1 3/4 stainless works headers , manual rack and pinion in a 89 camaro.Also, i hooked up zex direct port kit on it. havent run it yet. It should be wired correctly, but I dont know if the system is activating. I looked in the dashboard and figured pa enable should switch from 0 to 1 when parameters are met. I reved it to the 3000 mark with the switch on, but I didnt see the pa enable change. Any ideas on how to test the system to see if its working? The car is loud so I cant hear the solenoids. I could have a friend meter the relay while I activate and rev... I wired switch from 12v power to switch, then from switch it splices with pa enable from computer and goes to the relay. Theres a blue wire(forgot the name) that goes from computer to the relay. It should ground when parameters are met, activating relay, and sending the power from bat to relay, from relay to solenoids. anyone see any problems with this? this is pretty much what the wiring diagrams said to do, but there were 2 different ones from fast and 1 from zex.
