I have a 88 Hatch with a 90 Si block, 92 EX head, 90 Si Distrubtor. The car runs great but i can't get the vtec to work all of the time. I bought the MSD RPM Switch and it doesn't work at all. So i resorted to my shift light. But now when my car revs past the point of about 4300 (vtec is set at) the tach goes all crazy sometimes reading 10000 rpm? WTF if anybody has done a MINI-ME swap and has some insight on this problem please email me.
