well i sent my ecu p28 in to get s300 installed i'm running d16z6 turbo...they gave me a pr4 back and i noticed its a non vtec ecu...will this make a diff? sorry if its a dumb question. thx in advance..
I would suggest contacting Garage 5 then. You can use a non-vtec ecu to operate vtec with an s300 but it requires extra wiring nad a relay. You should gt the ecu that you gave them for socketing.
