I need a cheap way to make a VTEC Controller or if there is a cheap one for me to buy for my D16Z6 swap into my 90 sedan. Got any links on how to do this or people that have made VTEC Controllers please help. Engine is in & that's about all that's left to do! Thinking of using a 88-91 Si ECU or the PG7 88-89 teg. Thanks in advance!
