    F23A1 to H23A swap throwing Cel

    The only thing I can think of is that the various speed sensors are not wired correctly and the ECU isn't sensing the speed and not shifting as it should...

    F23A1 to H23A swap throwing Cel

    If you run the ECU without the immobilizer chip, it will start after 2 seconds in IG2 but once the car starts, a CEL will stay on the entire time. I'm not 100% sure what it does but I imagine that it will limit the performance or some functionality.

    F23A1 to H23A swap throwing Cel

    Quick update since I'm here anyway... I've been running the PCD JDM Euro R ECU for several months now and it's working perfectly. Though I finally had the AEM setup quite stable, it was nice to go back to an OEM ECU and not having to worry about anything anymore. The only hurdle will be...

    F23A1 to H23A swap throwing Cel

    It's the same as the OBD1 dizzy where all the sensors are in the dizzy. Look up some 4th gen prelude service manuals. All the sensors are in the dizzy.

    F23A1 to H23A swap throwing Cel

    Just a quick update from me... I'm still using the AEM EMS with wideband and I still pass emissions but because it's my daily driver, I'm sick of always having to mess around to get things right. Good thing this winter has not been too cold so all the cold starts have been fine but I'm still...

    F23A1 to H23A swap throwing Cel

    Hello, long time no check in for me but I'll stop by from time to time and give any info that I can. If you are putting this engine in a USDM car mainly is the ECU mismatch problem. This JDM engine does not have the crank sensor or crank angle sensor at the oil pump as the USDM engines do and...

    F23A1 to H23A swap throwing Cel

    Not a lot of update but I thought that this may be a significant one... I've sourced a JDM Honda PCD obd2b ECU. This is the closest matching OEM ECU for the H23A VTEC engine aside from the original (which I can't remember the code) Auto ECU... I'm going to try the PCD ECU and see if it does a...

    JDM OBD2B pinouts for Accord / JDM Accord Service Manual

    I've been looking around but I have not seen any resources that show JDM OBD2B Accord pinouts. I've seen the Civic OBD2B pinout by ff-squad but nothing for the Accord ECUs. Anyone have access to JDM Service Manuals? USDM Accord OBD2B pinouts are slightly different from EDM Euro Accord OBD2B...

    EDM Accord Type R ECU PDE for the H22A7 engine

    The immobilizer can be defeated and I will provide the details to the buyer.

    EDM Accord Type R ECU PDE for the H22A7 engine

    I've got a working EDM Accord Type R ECU for the H22A7 engine. I've socked the immobilizer so all you have to do is drop in a Doctronic unit or your own immobilizer and it will work perfectly. I can provide the buyer with key programming tricks as long as you still have your original ECU and...

    F23A1 to H23A swap throwing Cel

    The European PDE ECU has an immobilizer that is almost identical to the USDM 6th gen immobilizers. The transmitter at the key is different but the immobilizer "chip" inside the ECU is the same as the USDM ones. I have a PDE ECU and in order to get it working I pulled the immobilizer chip from...

    F23A1 to H23A swap throwing Cel

    So I've discovered that the JDM Euro R uses the PCD ECU and is a JDM H22A with 3 wire IACV, electronically controlled EGR and all the Crank Position, TDC, etc sensors located in the dizzy. The European Accord Type R uses the PDE ECU and is a EDM H22A7 with 3 wire IACV, electronically controlled...

    Going OBD1 from H23A VTEC swap

    Yup. The problem is not so much the CEL in itself, the problem is that you can't throw a CEL during emissions testing. Also, a piston misfire CEL will send your ECU into safe mode in and you will run pig rich and definitely fail emissions. I tried to pass emissions with my original ECU and...
