Ookay. . . Ectune cal is set for GM3bar, and when that map sensor in the car, it rund like crap. when I plug in the stock honda map it idles and sounds like a new car and runs really nice. I checked the wiring per the hondata write up, and It seems to be good to go. also, I tried another new Gm3bar... any ideas why shes actin like this??

sounds like the map sensor is not selected? did you select the sensor and press save?

Look at the voltage and mbar value with key on engine off, its very easy to wire them backwards cause they plugs are reverse from what makes sence. Double check all that. If your car does startup if your cursor is all the way to the right side of the map then its not wried properly.

My gm 3 bar reads 5v between A and C. KOEO 1.3v and yes it is saved for that map sensor.
