Hey guys, i've had a set of RC 750cc injectors for a few months now. Recently I just put them in running my new setup. I'm running a chipped p72 on uberdata, i've tried several different maps and nothing seems to work with them. When the car is on and i rev it, it just doesn't wanna go, it sputters and the engine cuts out, best way i can explain it is instead of vrooooooooooooooom, its vroo(die)vroo(die).

Leaning the **** out of the map does nothing at all. So, being fresh out of ideas, the only other thing i could think of is maybe i was sent PH injectors ?

I'm trying to get my hands on some sat. 440's but the kid never gets back to me, so i might just have to sell these and buy a different, smaller set.

Any ideas?


EDIT:: wanted to add this - the car runs perfectly fine in and out of boost on my stock injectors. People just tell me that i need to get the car tuned, and it cuts out because its running rich. But what i don't understand is if my stock injectors can run as rich as 10:1 before i fixed the map, why wouldn't the 750's?? Why wouldn't the stock injectors act the same way and cut out and be completely undrivable running super rich.

ohm them.
2-3 ohms = peak and hold
12-13 ohm = saturated
whats the part number? if it starts SL they are saturated.

did you scale the fuel maps for the bigger injectors? you should be able to work with the 750's just fine unless they are the wrong type. look at the part # on the injector. SL = saturated PL = peak and hold. or you can just measure the resistance as stated above.

ok, sweet thanks.. i'll check it out, and yea i did scale them.

The 1st map i ever tried was made from my friend (todaparty) on here. He even fixed it up where it was mad rich and the same exact things happened.

They're SL, ****, guess that theory's outta the question. I dunno what the hell else it could be, cars completely undrivable on these damn things.
