pull plug wires one at a time to see if its an injector.

i had problems before with my fuel rail being too tight, and "pinching" in injector semi-shut.

who ever made the rom you are using probably isn't using a stock map. could be a motorola or a gm you may need to make your own rom. just import the tables from the rom you want to use and when you add boost tools select your stock map.

i tired that too. it still wont do it. at first it was MY map and i started looking at other peoples maps and mine was screwed so i redid one...that one looked a LOT better but then it still did the same thing... then i tried that other map i posted and it still did it. i could take fuel out of it and get it to run a little better but it still wouldnt idle. i know the soldering and all is good because i put the computer in my brothers car with a p28 map burned to it with a 2500rpm rev limit and it only reved to 2500 so its not that.

my complete setup is
88 crx si
b18a1
p28 kind of on crome
xenocron conversion harness
plx m300
moates datalogging
skunk 2 intake manifold
drag exhaust
.48/.60
hmt style 3 inch exhaust from the turbo back and charge pipes
11x31x3 intercooler
xs wastegate
greddy type rs BOV

i doubt that helped anyone much but just incase. ive been through everything i know to do short of make a map in uberdata and see what happens there. maybe ill try that and burn it tomorrow.

Oh okay dude. I'd say it's a mechanical problem now. with the car running take a screwdriver hold the tip on each injector and put the handle to your ear. you should hear clicking from the injectors opening and closing.

If one isn't clicking you have an injector stuck open. have you checked your plugs I don't remember if you did or not. If one is wet and black and the others aren't that will tell you to. see if you can find some other injectors to swap over to just to check it.

yep, i checked today to see if uberdata would fix it with no luck. i didnt get a chance to check the injectors today but i pulled the plugs and yep, you guessed it, theyre fried. i reckon ill get some more tomorrow, check my injectors and see what happens from there. ill let yall know, thanks

a friend of mine had the same problem, we went through everything thinking it might be the tune, then checked all the sensors...ended up being a faulty injector. hope that solves your problem.
