Default RE: Put in some bigger injectors and now it won't run...

Does anyone read the entire post before jumping to a conclusion?

-I realize that it needs a tune to run properly and I am getting one but I wanted to know if my car should even be able to run to make sure that I didn't leave a wire disconnected or something.

-My sig mentions that I have a 90mm lightning meter. Not a stock meter

-I know for sure that the computer does the injectors size calibration. VRISTANG is right "The LMAF won't get "calibrated" for the injectors.
". Pro-M and other meter companies use the injectors size to help creat a flow sheet that is in the right range. Essentially as long as the meter is not pegged a tuner can make it work. Not that it matters because the LMAF uses 42lb injectors on the factory setup and it cannot be recalibrated.

Anyways thanks for the advice. Thank god I don't listen to all of it...

try re seting your ecu it may start after and give you enough time to get it to the shop.

if your running a lightning maf and 42's your car should run without puring black smoke. try reseting the computer and go from there

I think the problems is with already having a tune for my previous setup and not working off of a stock computer.

I ran the chip buy the tuners and he put on a safe tune for my setup (He does alot of 5.0, including his own so he knows what he is doing). I'll throw it in tonight and see what happens. Hopefully it will be good enough to get me to the tuners tomorrow.

Thanks for all the feedback.

Did the temporary chip work?
I'm sure it did, it shouldn't be a tough change to get it close.
It may run rough for a few minutes though LOL

Good Luck Dude
