Greg, if you dont mind me adding something...
Make sure you've got a solenoid hooked up when you install the harness and are tuning the ECU. With nothing pluged in you will NEVER get it to switch maps, and tuning suddenly becomes very uncomfortable! I had left the solenoid connector unpluged, since I didnt have a sol. to wire up at the time and am not ready for the spray, and ran into some royal headaches. Even if you have to borrow one for tuning, make sure something is plugged in there. Thanks again for all your help getting things wired and figured out!
