    I own a Prelude 2.3 Si '92, and now in process of swap. For swap - JDM H23 VTEC engine from Accord SiR 1999. I got the ECU from the Accord, but I guess it's a wrong one. The full text printed on the ECU box reads:
    2H
    37820-PCF-N51
    CY-EH2955A
    NO, 11250 -1
    Matsushita Co.

    Questions:
    1. Is it possible to use OBD1 P13 ECU with OBD2 engine H23 VTEC?
    2. Is it possible to use OBD1 P14 ECU (my old one, non-VTEC) with OBD2 engine H23 VTEC? (I understand that VTEC will not work, but will the engine run at all?)
    3. What is the code of my new ECU from Accord, is it CF?

    Please help! SOS!

    you can use a p13, but need to convert the motors electronics over to obd1 to match the ecu, i think distributor and possibly injectors are all that would need to be changed but not positive...

    yes, your motor should run with the p14 minus vtec, but you would need to convert the motors elec's over to obd1...

    check into a obd1 to obd2 converter, this might let you use the new ecu you got with the motor...

    post pics of the motor please, i have never seen a h23vtec in real life, whats the block stamped as just h23? or h23a? or what?
