yeah i did the search too! and found some threads(ive read them all) and none have answered my questions.

anyone out there with real advice? instead of "search minime"..."look at old threads".....its been on here sooo much its so common'......blah

i need to know if i can use my stock ecu, im assuming i can because the o2 sensor should remap the fuel ratio once it sees its running lean(when vtec kicks on) ?

if for some reason that wont work then....

can i use a p28 ecu and have it chipped to map my fuel mixture for the vtec engagment (which is going to be independently controlled by a rpm/relay switch) ?

 

It wont.

If you want to be cheap but in a semi safe way buy a VAFC. I still think try turboedit and remap your ecu or just get the right ecu and wiring.
