Why didn't you just get the ECU chipped to control vtec? anyway, the ground has to be run through the msd box so that when the rpm level is within the window you programmed, it will ground, and allow vtec to engage. (I think that's how you do it. that's what you do with a nitrous system anyway.)

PM6 won't control the extra fuel needed for the bigger vtec cam.. Tippyman98 knows what he's talking about.
