Myself, and the other mods have been very nice and lenient with the rules. We have been deleting threads, and giving out warnings. Some members didn't get the clue and re-posted over and over... Now ANY member buying or selling in this section will be banned... No IF's AND's or BUT's.

    ICU same on '90carb vs '92inj.?

    Would like to know if the ICU is same on the 2.0 '90 carburator Accord and 2.2i '92 injection Accord? Tried to look from http://www.hondapartsdeals.com/honda_parts.php and got the same ICU's but can't tell if it's the same on carb.

    While I'm not one hundred percent (only like 99.9), I have to say no. The ecu from the carbed motor wouldn't be programmed to activate the injectors. The other way around wouldn't work either, and i think you're looking at different obd versions as well.

      Can you clarify what you mean by ICU?
      Coil and ignitor should be the same, yet the dizzys are different and the plugs / wiring.
      And the ECU's carb / pgmfi are not interchangeable.

      If at first you don't succeed, Try again. Don't give up too easily, persistance pays off in the end.

            I mean the number 27 from that page. It should be changeable, right? Or do i have to change the whole relay-fuse box?! And yeah, in Finland the 2,0l accord is more common than 2,2. And yes, we have '90 carb. accords. I don't mean ECU, but the control unit which controls the wipers etc... Or i have really misunderstood everything? Hope not. Part number 38600-SM4-A01. ECU control the engine as for my knowledge and the ICU controls wipers and lights and some other stuff...Correct me if i'm wrong

            Found another one also...

              Ahhh.... I see now..

              From what I can find they appear to be the same unit. Since it doesn't control the engine, they seem interchangeable. In fact, I saw quite a few sites stating the same part number for 90-02 Accords.

                Well we see in a couple of days if they are interchangable. Ordered new unit for 20€ so it's not much even if it doesn't fit. But seems that no-one knows what ICU is when i've asked it here in Finland. Don't know if it's the official but on the Haynes it's called ICU(integrated control unit). But good to know that they should be. Like I first posted they do seem to be the same, but you can't never be sure know with these electric parts.
