This Poll will be a determining factor for our future development priorities.

What type of ECU are you running?

  1. I have Accord with 5-pin DLC will this also work?

    1. The compatibility with 5pin DLC has not been tested yet, if the ECU is HOBD1 variant it may work just fine. The 5 pin direct plug-in interface version may be released later.

    2. It is 37820-PDE-E03 (1999 UK) so could be OBD2 B but without 16-pin DLC and also its 5pin DLC last pin is empty. Will try 5pin to 16pin adapter first.

    3. I'll look into this matter the next year.

    4. False alarm. It seems if outer 5-pin wire is missing it means it is routed to 16-pin DLC located somewhere. 5th pin is for ECU OBD and 4th pin is for ABS, so most adapters which convert 5-pin to 16-pin ODB2 won't work as connect to ABS only.
      Traced from ECU A21 (K-line) pin that it is located near console at left side of passenger legs - http://www.ardio.ru/dlclocs/hondaaccord2000lhd.jpg

    5. So the actual connector which has K-line wire is the one on the picture? How does the 5pin DLC looks like anyway?

    6. It looks like this:

      As you can see OBD2 compliant cars are missing 5th wire which is K-line for ECU diagnostic. So only question would be for cars which have all 5-wires if it is OBD2 but without OBD2 connector or it is Honda OBD protocol.

  2. A lot of people in the UK run a modified P28 like this:

    1. Yep, that's a custom chipped OBD1 solution, which has so many clones. I'll see what can be done about it the next year.

  3. Hello, i have been running this in my 99 Prelude for a year now and it's by far the best most awesome bit of tech ive had for a car. I am now upgrading to an Accord type R with a 16 pin OBD2 connector. Do you have any idea when you are able to support the 16 OBD2 ecu's like the Accord Type R ?

    P.SThank you for your hard work, the interface and software are top notch

    1. Thank you for the appreciation.
      Update with support for ELM327 interfaces will be released in a few weeks. It should work on all 16 pin Hondas as well.
      There will be no custom Hondash OBD2 16pin interface as the development cost are just too high.

  4. Hello,
    thanks for your great product!
    Unfortunatly i couldnt test it on my own car.. because I have p28g03 obd2a ecu and i've disabled my immobiliser because i dont have my red key and i've done a minime swap to d16y8! Do you know i get my 3-pin dlc connector to work? And what does the immo have to do with the 3-pin dlc? Thanks in advance.

    1. there are two options, you either get a ECU which doesn't have a immobilizer from factory, or chip the ECU with Crome map, but the Crome might also not work as some users reported. The reason is yet to by determined.

      Regarding the immobilizer, I've seen logs from Hondash running on ECU with disabled immobilizer, the communication is invalid, disrupted by random data stream clashing with data sent from Hondash.
