Well i had been trying to fix the ZEX box cuz it wasn't sparying. So i finally did today, put down the timimg to 5 degrees. And went for a quick spray, it was bad ass. Only in 1st and 2nd though. After about 15 to 30 seconds the CEL went on. and it was 124 TP sensor above voltage. I turned the car of then on and didn't turn on again. I also had that 212 one again. Why would the 124 turn on while spraying? Can i mess something up? Im not spraying again cuz i was making sure it worked cuz its the only way my window switch while let it spray
 
Are you sure the wires are hooked up right? Your not sending any voltage to the tps?

IF you want to test it out without driving, pull out the nozzle and put your thumb on the hole, and move the thrott. by hand. Just make sure the nozzle is pointed away from you/ maybe make a PVC tube to mount it in and put like a trashbag downstream so the gas goes into it. Have a buddy sit and watch the tack to see if its coming on at the correct rpm.
 
cuz im running 87 octane and im untuned. and yes my car is spraying, i can feel it and smell the burn. And we did revv up the engine while the hose was of and yes it did spray. I have a window switch, so it turns on and of at my desire rpm, just incase some you dont know
 
:OT:

87 oct + nos = bad for your engine and performance

Definitely would consider premium and 10 deg timing. I would think this would be a good base tune. And adjust from there.IMO Good luck tho.:nice:

As far as the 124 code beats me never had that problem..
 
your suppose to retard the timing 2 degrees for every 50 shot. So 100 shot would be 4 degrees retarded. And i ment a little lower cuz of the the 87 octane
