i have hondata s200 programed to run bc stage 2 cams, i/h/e, stock bottom etc..now my friend wants to use my ecu on his gsr, same set-up besides the cams, he has stock cams and i dont want to mess with my ecu, will his car run fine i mean will cause any harm to motor if he uses my ecu?

 

ok we pluged it in, the car ran like a champ!! but it would of done better if he had cams, still alot of wheel spin even w/o cams and stock valvetrain weird... the only thing that went wrong was the CEL came on but when we tryed to jump the plug and see what code it was throwing, the CEL would turn off when we put the paper clip in why?
