i got myself a 92cx b16a swap.
best guess is the motor is out of a 1989 or 1990 jdm integra
so i got hold of a p28 obd1. ebayed a skunk2 chip for 92-95ex 4800rpm vtech
i chiped it myself because i wasnt about to pay $60 to have it done when i could do it myself.
i swaped the ECU's and drove my car around long enough for it to warm up. then i ran it through 4800. no vtech. drove around some more. tryed to get it to vtec and still nothing

my cx has a single prong o2 sensor im about to change out this week.

does anybody have any ideas why it wont vtech
