Well I had the emange blue, and when we fist stared it up the emange would be on but wouldn't control anything, and the car ran on the factor stock ecu maps (like the ones when you first turn the car on the very first tiime you buy it, lol) But it only did that when you turned the car on and the emanage came on at the same time, but when you turned it on and then turned the emange off and the back on it would work..so we figured out it was a wiring issue and fixed that.....but that was why my car was running pig rich.
