Ok just so ya know I'm not very experienced with the ems obviously but I'm at least trying to get the car driveable so I can just make sure there aren't any problems. but anyway the car idles fine. but when try to drive it above a certain rpm prolly around 2500 it sputters like hell and won't go any faster at all. and I also noticed that if I click on the home icon inside the ems with the car running it isn't registering any rpm's so I was wondering if that could be the problem. I was thinking that the ems might not know what rpms the engine is pulling so it doesnt know how much fuel and ignition timing etc... to do...but I was pretty sure I plugged up all the sensors and everything. please help me out and give me your opinions..

thanks

 

need some help bump

 

Why don't you use the data logger in the aem to see whats going on.
