ok i searchd but couldnt find anything helpfull. i have a 92 hatch with a d15b7 and im swaping to a d16z6 can i use my old ecu and just wire up the vtec or do i have to get a p28? and i kno there was a diagram on how to wire up vtec but i can not find it if any 1 has the link that would be great thanks.

 

I think you have the p06 ecu, which it can be converted to a p28. Check pgmfi.org to find out how to make the conversion.
