    H23 ecu question

    So I have a H23a1 in my 93 Accord and it has a PT6 ecu in it and i'm getting a cel code 8 and I tested the wires and dizzy and everything is good. So i'm gonna replace the ecu next but should I get the PT6 again or the ecu for the H23a1? Thanks (I'm used to D series this H/F stuff is all new to me)

    u need to get the h23 ecu to make sure that its giving it the right amount of fuel and what not.......the motors require a different amount of fuel and the injector sizes are different i believe so if ur ecu is dumping 55% duty cycle on 210cc injectors instead of 180cc injectors (making up numbers lol) it'll make you run rich. To put it simple:


    get the h23 ecu

      I have a manual P14 ecu that is for a USDM H23. PM me if interested.



      Please do not sell in the Beginner Forums. Disregarding this rule in the future will result in a permanent ban. - Staff.

                h23 ecu calls for a knock sensor, but since you have an h23 it's as simple as getting a knock sensor and running the wiring if not already done...

                p14 ecu + no knock sensor signal = shitty ass retarded timing

                if you have a cel with the pt6 and you KNOW the ecu is in proper working condition, swapping ECUs will not make it go away... i personally run a JDM F22B w/ a pt6 and have no CEL problems...

                    Shit, I forgot about needing that knock sensor.

                    I knew I forgot something.
