Im running a non vtech JDM d15b with a 1.6 intake plenum and a del sol tranny. i was running on a po5 when i got the car and now i bought a virgin po6 and i plugged it in and now i have a check engine light on. can anyone tell me if thats the right computer and if it is then why do i have a check engine light on. By the way i have 40,000 on the engine and tranny.
