How do I tune my Vtec controller?

91 Integra lsvtec vafc ii vtec controller vs ecu vs per chip?

  • i got an 91 integra with an ls/vtec(b16a/b18a), all internals are upgraded nothing stock, okay right now i got the stock ecu(pr4) but with the vafcii vtec controller, i like the fact i got control of the vtec and i could shut it off if i want, the problem im having is im only hitting 7000rpms redline...i want something more in the 8000 to 8200rpm range, whats the most reasonable way i could increase my rpms? should i just chip my ecu to hit higher rpms? if so is there a good website to get my ecu chipped? i want to swap my ecu as a last resort, but if i have to i'll do it, it just seems kinda complicated because of the obd0 to obd1, any help appreciated, thanx

  • Answer:

    Take that vtec controller off. Go with hondata. If all you wanna do is raise the rev limiter then go with s100. Your gonna have to do an obd0 to obd1 conversion but it's not hard. Heres an website that would help you out with that http://www.g2ic.com/forums/showthread.php?t=86612
