I just installed a 600 kit. The engine starts and runs but the AFR is stuck on 14.9 and the target is  13.5 at idle. The car won't idle. read about a problem like this with other installs and it said to try reprogramming the ecu. The problem with that is the handheld won't let me "unhide" that option on the display. Any help would be appreciated.
