    Exclamation Project, 4g Distributor / Ecu ( Obd-1 )

    My brother pulled it off. His 88 accord is now OBD1. Its running a F22 accord distributor and a ECU conversion harness. We've been trying different ECUs aswell. We've tried the stock F22 ecu and a stock P75 LS ecu. Both ecu's ran better then the old setup, but the P75 ran the best with good idle. Lowend torque and smoothness was definately felt right off the bat. The engine revs up much quicker in nuetral and pulls harder. This also really opens more possiblities for ECU upgrades with all the modifications available for the OBD1 ecu's, probably gonna get a chip next for the P75 or tune our AEM EMS to the A20. We hope to take it to the dyno soon, looking to make 150+ hp now. anyways more details to come.



    oh by the way, we still have one complete B20a 5speed package that we need to sell. Email if your interested.

    Whats the P75 computer? How do you make a conversion harness? What year/model F22 ecu and distributor did you use, there are differences between the years, not just models or generations, I have alot of these parts was thinking about doing the distributor swap for years...

    mike obviously hasent been following the GM progress. its ready to close now. had to sort out some details and get it clean enough to pass emisions. belive it or not emisions and gas milage and performance dont mix. gas mileage and performance no problem. keeping the catalytic converter happy that a whole different story. mike get in touch.

    So his shop made a dream into driveable reality, we should be happy instead of, "but what about me and my work".

    We also need to remember that this information is brought to us as a gift. But as such, mike is in the difficult position that since this was created at a shop who's business is dirived(ms) from doing this kind of work, it may not be in their best interest to give you complete details, least people not give them that business. So, mike may or may not be able to shaire with us a how to. If we can't have a how to, just be greatfull that you were given a heads up on a factual working system that gives you a alternate route to take in doing such a system, yourself.


    I for one am gratefull that mike did the post, thank you mike.

    my point is that the obd1 honda ECM's are a step backwards. they still dont have knock protection and to top it off the f22a dizzy is prone to spark scatter and module death. im not critizing. im just saying. that hondas hardware and software arent tunner firendly. and for what it would cost to scavange the parts you could have a trick GM setup and it would be 10x more programable then the best hondata setup around.

    that is very true, just ask any 4th gen owner, those internal coils and the ignitor modules fail very commonly, and at like $150 or so per ignitor from honda... damn... Oh yea and Hondata aint cheap at all

    Playing devil's advocate for a bit... After market caps are available that allow you to run an external coil, I'd like to think that they help the spark scatter as well.

    I would much rather have the DIS and be done with it. That is just my personal opinion.

    yeah that is better in terms of reliability and sheer tunability... i mean, no distributor to fail, its just harder to install and get it to work, custom fab stuff is involved.

    Wow, this beats paying USD$2400 for a Haltech E6X. I would kill for the possibility to run Uberdata AND DIS ignition in my 3G. I think I would pay up to USD$1000 for having a OBD1 (chippable and Uberdata capable) ECU running in my car. I don't know what you pay for a P75 ECU over there, nor the cost of the conversion harness, or the OBD1 distributor, but (in a while) I will need programmable fuel management, and if it's cheaper than the Haltech, sure, why not?

    Building a fast Honda with mostly Honda OEM parts is a thaught that makes me happy.

    this is something that I have thought about but like SEAN said there dizzy isn't the best, My bro has replaced his module twice so far in his 4G and he has had the car for a year.

    Sure wish Mike and Darryl would share some more information on this swap though. I'm trying to do the same thing, but it is very slow going reinventing the wheel. C'mon, guys, how about it? I'm sure I'm not the only one who would like to know more about how you did this.

    Well guys I don't want to be an ass but this is an easy conversion...

    Look at the picture carefully. The bottom bolt (not shown in the picture) should line up without problem. The rear top bolt is held in place by a custom bracket and spacers (probably). The front top bolt may or may not line up but it's not a problem... the carbed 3g distributor is held in place by 2 bolts and does not suffer in any way..

    For the wiring, you need to add the 2 wires for the crank sensor and 1 wire for the igniter. Some of the 4th gen Accords had an external coil from the factory (depends of the years) so the internal coil failing isn't a problem. If you're worried by the igniter, just get an external ignitor from a 3rd gen Prelude.

    The rest of the swap is just a wiring issue which is pretty simple I think.

    He used the F series distributor but the D or B series might just work as fine (or maybe better)

    I do not have an A20A anymore so I can't really help you on this one...
