I have an ls turbo in an eg si. The ls has wisceo pistons, eagle rods, 440 injector and have neptune as my tuning. The problem is that there is a miss fire which i can't understand why,

i got everything back in order my problem is when the car is cold it sound like **** (misfire)
when the car get to normal temp above 180, you mess around with the plug wires and then it will work fine a drive fine no miss fire. I've changed the spark plug, wire rotor and cap. Today i put my gsr dizzy and plug wires on my ls turbo and it did the same (misfire) so does anybody knows whats wrong

Maybe you have your firing order wrong. Your question isn't easy to answer with the info you provided.

 

injector wasn't plugged in all the way and timing was off a tooth plus i didn't have the resistor connect right is i have a dsm injectors but still have the hks blow off valve that doesn't sound right

 

u drunk bro?

 

lol.. i couldnt tell if he was making fun of himself or not?? so u didnt wire the injectors correctly? and ur saying that the hks blow off valve isnt "blowing off" right? please clarify

mess with the ect or iat fuel and ignition corrections in Neptune. sounds like you only have problems when cold. I ended up adding more fuel in these parameters leave the fuel and ignition maps alone. btw what do you mean when you say mess with the plug wires are you switching them around ,, are u trying to reseat to make sure they are contacting

 

just when im trying to reseat them but the only way it will work is if the car is hot or warm then it will run fine till then it just misfire my wideband doesn't read it

 

Wow OP must be drunk or on drugs

 

hey what do you mean
