Hey guys i ve been helping a buddy of mine he has a 95 prelude with a jspec H22a in it i think we have the vtec hooked up right i mean we didn't run it directly to the computer we used the existing ports because the si come pre wired for the vtec but when we go to hook up the ground wire it cuts the rpm gauge from working, i think we had it hooked to the thermastat and it cut the rpms but then we moved the ground to somewere on the chassis and it still cuts out the rpms. what do you guys suggest for this should we try and wire it stright to the computer, and also he has a good size dent in his oil pan ive read that, that could be the problem also.
Thanks guys sorry for a newbie question need help

 

sorry cant help you but thanks for spelling vtec right
