hey,
i just instaled a eliminator(gt2871rs), myka ecu, 550 injectors, test pipe n my car is missfiring like a crazy!!! any ideia? and i did change valve cover gaskets and coil packs n spark plugs,i almost cant drive

[Poopie]

did you try unplugging your maf? Ditch the tune too...it is absolute crap. Do you have a wideband AFR meter?

Check that MAF

unplug and plug your ICM. i know when i did my FMIC i took it off and when i installed it i was missfireing. so i just disconnected it and connected it back in. do the same with the maf and get a new tune like poopie seed. can also be you plugs.

Is it the right MAF size?
I ran a MAF that was .5" smaller and it misfired like NUTS

Did you just install this? Because the ECU needs some time to adjust the fuel trims, which means you need to drive it around at part throttle for it to do so. It isn't like the tuning is going to be perfect on your car right out of the box.


What FPR is the setup tuned for and what FPR do you have in the car?

What are your spark plugs gapped at? As your boost level increases you need to tighten the gap up on the plugs, or increase the output power of the coils. Gapping is cheaper.
