Next time I see my car it's gonna be boosted. It's a CRX woth DOHC ZC, but has the PM6 ECU.

I know that a PM6/PM7/PG7 aren't gonna be enough fuel for probably more than 4-5 lbs. I have no idea what the boost is gonna be, but richer is better in my case.

Should I use a

PWO
PR3
PR4

Also, without VTEC wired, I still should get the VTEC fuel maps on the VTEC ECU's or no?

best ecu n/a is the pm7, it was designed for your motor so it should be used with it. if you are boosted, a chipped pm6 or chipped pm7 will accomplish the same thing. you will be modifying your fuel maps anyways, so the original map wont make any difference
