ok well, its been about eight months since i put my U12 in my Nx, and so far i still cant get it to run smoothly. Ive asked this question before with no response on of web sites. Im just wondering for those out there who have done this swap, if they have used a jim wolf technologies reprogramed Ecu or not. and if not how does your car run, and what did you have to change, along the lines of your throttle positioning sensor. Because the U12 ecu im running in my car is not reading that sensor, and therefore the idle just does what it feels like. I need help, or this car will never run.
