2 shielded wires going directly to the ECU...The colors are Blue-Yellow and Blue-Green.
You can use the cold advance solenoid wire as the igniter wire, that way you don't need to add a wire for it. Since you'll be using an electronic advance distributor, you will not need the cold advance solenoid anymore.
I will post a wiring how-to tomorrow about this

Yeah mike, get in touch, so he can take your money, feed you bullshit, and not send you a damn thing, your money back or the kit. You should jump all over that one. He won't send me my money back and I'm still waiting for the kit, and its been almost 5 months.Originally Posted by Sean

Oh, and your ECM? It is getting worked on, just so you can feel special. Also, you are welcome for wondering around in the 115 degree 100% humidity heat two weeks ago to find you a workable distributor.

you guys need to seriously stop this pitty fight of yours in all the threads you guys come across. Not to point fingers here, but i know there has been threads made, replies given and things are still bitter. But that does not mean it has to be brought up every once in a while. :duh:
Yeah, this thread was getting really interesting.... Yo Carot, I hope you do the write up on this....
Check the engine swap sections... wiring this distributor should be same as my PK2 ECu conversion.
I suggest you get a distributor with an external coul (less wires to mess with) The igniter can come from a prelude (external) or you could use the one in the distributor.
In any case, you will need an obd-1 or obd-2 distributor.
Here is the thread:
https://www.3geez.com/showthread.php?t=31622
I will add this to the How-To section soon when everything is cleared.
All you need guys now is a way to mount an electronic distributor on the A20A. If you go with the Pk2, the 88-89 A20A has already 2 O2 sensors so it's not a problem. If you go with any OBD-1 engine, you will need a 4 wire O2 sensor.
If you have any questions, feel free to ask.

this is nice, now I just need to get the parts together, and have some fun with uberdata and get some more dyno time.
I'm your local R&D nut. Fabracting, welding, tuning and breaking my stuff so you don't have to.
Questions:
1 - Which 4G has the ignitor outside the dizzy? Like year/trim level/etc...
2 - How do you make the conversion harness for the ECU?
I am VERY interested in doing this, and the more help I get the easier it will be for me.
Thanks.

did you check the other thread? it has more info there.

Nothin' 2 Old Racing
Is there a better OBD-0 ECU we could use for our 3geez? I did a search and I don't want to bother with OBD-1 conversions. I just want to plug in a better ECU without the hassles. I could buy the JET performance module for $250 or the VENOM for $400, but I wanna use a better OBD-0 ECU first.
no, no other ecu will work without extensive wiring modifications and swapping distributors. Swapping to obd 1 is the best idea
429whp 362wtq A20 TURBO. A20T>*
do some searching on PGMFI.org They will have the best info on what is the better OBD-0 ecu, but you will have to make at minimual some changes to the pin locations. I think it is that civic/CRX ecu that is the most tunable, can't remember for sure.
I'm your local R&D nut. Fabracting, welding, tuning and breaking my stuff so you don't have to.
cool, thanks. the reason i wanted to stick with OBD-0 is not only the ease of simply matching up wire pinouts, but also less emissions control = more power. unfortunately the A20A3 PJ0 ECU is not very tunable. yeah justin, you're right...i've found the 88-89 CRX/Civic PG6/PM6 ECU is the closest ECU to the A20's PJ0 other than the 2nd gen Lude's PK4. Look up 88-89 CRX/Civic PG6/PM6 pinout and compare it to the the A20 pinout. Looks almost identical and even has an EGR pin. I just wonder how it runs in the 3gee.
OBD0 CRX ECU codes:
88 crx - PG6
89 crx - PM6
JDM crx SiR - PW0
i might go the the j-yard and yank me an 88-89 crx ecu and try it out. if you noob guys do the same, make sure the civic/crx is 88 or 89 and ecu is PG6/PM6 cus those are the only ones that would work cus usually 90+ model year hondas started using OBD1. also. don't forget to match pinouts and verify before simply plugging in the CRX ECU. i think it's a 90-95% match. just watch out for the other 5-10%

Hey guys, I wanted to get a thread going on how to indentify what ECU you have so that I can make a link in the FAQ thread. (and for the noobs who ask )
So far this is all the info I got. If you have some more you can add, please do so. Thanks
ECU Part Numbers
All Honda ECUs have a part number which is located on the side of the ECU and inside the ECU on the connector. e.g. 37820-P72-A01
The part number consists of three components:
Honda's part number for ECU, which is always 37820
Three characters (which are loosely related to the model of car/engine). e.g P72
Three characters (which are the revision of the ECU) e.g. A01
The middle three characters are the most useful to identify what the ECU is. Different generation ECUs may use the same characters. e.g. a P72 OBD I ECU is different from a P72 OBD II ECU. Here is a list of common ECUs:
PG6: 88-89 Integra (all makes)
PM5: 88-91 Civic/CRX DX
PM6: 88-91 Civic/CRX SOHC Si
PM7: 89-91 DOHC ZC (JDM 'EF' ECU)
PM8: 88-91 CRX HF
PR2: 89-91 ZC (Euro)
PR3: 89-91 JDM B16A EF8/9
PR3-J00 or J51: 92 JDM Integra B16A EF8/9
PW0: 89-91 JDM B16A EF8/9 DA6-XSi
PR4: 90-91 Integra LS/GS
PS9: 88-91 4 door Civic EX Auto
P05: 92-95 OBD-1 Civic CX
P06: 92-95 OBD-1 Civic DX
P07: 92-95 OBD-1 Civic VX
P08: 92-95 OBD-1 Civic D15 JDM
P0A: 94-95 OBD-1 Accord EX
P13: 93-95 OBD-1 Prelude Vtec
P14: 93-95 OBD-1 Prelude Si (non Vtec)
P27: 92-95 OBD-1 EG JDM Civic 1600 sohc
P28: 92-95 OBD-1 Civic Si/Ex
P30: 92-95 OBD-1 DelSol DOHC Vtec Si/EG SiR
P54-G31: 1997 Honda Accord 1.8 LS
P61: 92-93 OBD-1 Integra GSR
P72: 94-95 OBD-1 Integra GSR
P72: 96-00 OBD-2 Integra GSR
P73: 96-00 OBD-2 Integra Type-R (JDM & USDM)
P74/75: 92-95 OBD-1 Integra LS/GS
P75: 96-00 OBD-2 Integra LS/GS

PIC OF WHAT ECU IT IS....
From top to bottom...
1. OBD IIb ECU
2. OBD II ECU
3. OBD I ECU
4. OBD 0 (JDM PR3 and PWO)
Oh and correct me if I'm wrong somewhere.

yea at least with the civic ECU you can change the fuel maps a little.
Have to get Mike to add that to the ECU FAQ, I'll Pm about it.
I'm your local R&D nut. Fabracting, welding, tuning and breaking my stuff so you don't have to.
IMO, personally i wouldn't bother with OBD-0 and trying to tune it... my friends engine went in her 91 accord so i'm going to jack the distributor, and find a p28 ecu then i'll be set... kinda lol... let us know how this ECU conversion goes though, i'm curious to hear the outcome.

I agree OBD-1 is the only way to go and if you guys find a distributor that mounts up your all set. I recently bolted up a 90-93 Teg LS distributor to my B20A after having issues with my JDM one.
Neptune seems to be a nice setup and my tuner is trying to get it but he is to close to someone else to tunes it already so they wont sell it to him. But there are a lot of options once your OBD-1.
I was asked to do a how to on this but decided since im running the AEM EMS that my pinouts wont be everything that you guys will need. The EMS is more forgiving since i can alter pretty much everything from my laptop and its easy to troubleshoot since it shows all the sensor readouts and logs. So basically the hard part is the conversion harness and i didnt have to modify mine much because Boomslang altered everything they could for me. The rest were mostly add-ons (knock, Boost solenoid, etc).

The only 90 and 91 OBD 1 Honda's were Accords. Integras and Civics changed for the 92 model year. An OBD 0 PR4 from an Integra LS would also be a great bet. You will definitely need to move some pins around to get it to work. I'm not sure how the ECU would only like 2 signals coming from the dizzy tho. The Integra dizzy has 3 sensors. Also, less emission control doesn't mean more power. OBD is all electronic. The only difference is an OBD 1 ECU has more trouble codes built in.

No projects. Life consumes my time and money.
Well, the Prelude SR 90-91 had the B21A which is OBD-1 . I wouldn't bother with any of the Prelude and Accord ECU tough. A civic ECU will do the trick as long as it's OBD-0 or 1 and that you can matche the distributor on the A20A head.

Basically its the same as the other OBD-0 to OBD-1 harnesses but they changed a few more pins since theyre not exactly the same pinouts.
has anyone ever tried out the 86-89 teg ecu out? I would think they would be better then are's and they are still obd 0???

b20accord SN on honda-tech,homemadeturbo,clubcivic,turbod16, and many more
well, they are really similar to the 88-89 PM6 ECU (Civic SI). I would get the 90-91 PM6 or PR4 ECU if I was going with OBD-0 since those 2 ECU already have an external ROM that is easy to replace. The 88-89 isn't impossible to chip but it takes a few more steps and hacks to make it work.
