Ive heard of other ways to engage vtec and was wondering what those ways are? I have a d16y8 with a p28 and I cant get the vtec to work, I am using the y8 dis. and my tach doesnt work, would the dist. have something to do with my tach not working and thats maybe why my vtec doesnt work. Please help, Ive asked on other forums and havent got any info. I just changed the vss, also my hatch began as a dx auto. Do I have to do anything to get a ex cluster to work, like run any wires for the tach? HELP!!
