Here is a what I think to be stock gsr 94 ecu. I just got it today. It makes my idel at 200-300 and then if I don't punch it it will blog in and out.



Where you see the red outline that chip looks burnt. I wanna know if I can replace it. Also I noticed that vtec kicks in at 4200 but I see all stock parts on this ecu. I just think it might be because if this chip it's bogging and vtec is opening at 4200.
