hi dear all . i have a 99'' prelude auto trans with F22A6 non VTEC and i just swap it to F20B1 with the original stock ecu and harness and the enging is working .......BUT i know i need to change the ecu to obd2 so the VTEC will give me more fun......so now what i need to know before i spend some bucks ... can i use the F22b or F23b VTEC ecu on my car with my harness but with adding the A8 VTEC solenoid
B5 VTEC oil pressure switch
B19 Knocksensor
C8 Second oxygen sensor
IF it possible please let me know and if it's not what i need to do
