Code for ecu

[MikeCX93]

I have a friend who has a 89 civic hatch. They dropped in a d15b vtec. I looked at it last night but couldnt see the code on the block(dont know if the last number matters) But if you know which ecu, let me know and if you have one to sell let me know a price and ill get ahold of her. Thnks

unless they convert to obd1 that motor will never run correctly, you can use a multi point dizzy with the correct ecu (pm6) and it will run but then they will need to hard wire vtec to either a msd window switch or a vtec controller of some sort.

The full correct way would be to do a obd1 conversion with a p28 ecu and wiring the vtec into the factory wiring harness.

Actually, the proper ECU to use is a JDM P08 ECU from the D15B. The P28 is the USDM equivalent and would be needed if you want to chip the ECU.

you can use an automatic ps9 ecu and use the torque converter lockup signal to engage/disengage vtec, or you can use pm6/pr4 ecu and use the ac relay signal to engage/disengage vtec. more info here
