My OBD-1 Conversion

[ZackieDarko]

nice


i will be doing this soon as well

[MessyHonda]

i want some too...do you have any rough estimates on total cost?

[ZackieDarko]

the OBD-1 people should get together and figure out an OBD-0 to OBD-1 kit and post it up so we can all enjoy the fun

well, first you have to hack up the distributor to make it fit. that will be interesting.
second, even with convertion harness, you still have to do a lot of wirring. For starters you have to run new wires from distributor all the way to the ECU for crank sensor. harness should come with 4 wire O2 sensor wirring.
After that you have to wire up the gauge cluster for speed pulser sensor.
it is not as easy as you think it will be.

[bobafett]

one thing to consider is that with most of the open tuning platforms you can choose to use a 1 wire or stock 4 wire, or even a true wideband o2 sensor, but really that is probably the least of one's worries.

IMO getting the dizzy mounted is scariest part.

we should contact painless wires and they want to build us a harness...lol

Yes you can heres the link.

OBD0 > OBD1 Harness: $104
Dizzy Adapter Harness: $50

You will have to repin some of the wires if you buy that harness. Boomslang makes a harness specifically for our Accords, I dont think they list it but they make it.

I was going to say our obd-0 is different then all the other obd-0's . Rywire can make an entire engine, distributor, and ecu setup. He has all the wireing digrams and knowledge of the convertion. I know some people have had trouble with him, but he has been very good to all my projects.

[thegreatdane]

I can personally vouch for boomslang as a solid product. I know rywire makes them too but as you said someone had troubles with it. It might just have been a glitch though.

[shepherd79]

i a lot of people who make wirring harnesses for our cars, but most of them switch wirring for sensors from the distributor to ECU.

I' will begining my obd-1 conversion shortly as soon as my harness's arrive, aswell as my SAFC-2.

did anyone else catch this?
what on god's green earth are you going to do with a safc-2?
the whole point of getting a chipped 0bd1 ecu is to directly tune the ecu via hondata, chrome, or neptune.
am i missing something?

damn looks hot....i always wanted to connect one of my laptop to my car...ever since i saw it on fast and the furious but yeah....kinda rice now that i think about it now...lol

it's cool as fuk to be able to see what you'r car is doing on the fuel map and datalogger but when you are rolling on a sat. night with the lap top sitting on the passenger side floor.eeh.... it feels kinda ghey..
but when the tunner is rollin with you! you feel like you'r the shit! lol.

Just do it yourself. Beats paying them and Then having to do it yourself, like I did..

plus that guy just reminds me of someone I used to know, and don't like. It's uncanny.

Anyway, good luck with the conversion. I wish someone had firmly told me obd1 is the unavoidable first step in modifying my car years ago. It would have saved me a lot of headaches.

I didnt know if you wanted me to acknowledge you as the one with the problem.

Reply to 89 turbo'ed, I'm going to be turboing the car, and I assumed it would come in handy. I just purchased an AEM UEGO wideband air/fuel as well so that's another peice of my puzzle.

Deal with that kind of headache! No thanks, Id rather just buy one thats done and just deal with a few wires as opposed to 100...

OK so what you're saying is not to get the AFC, what will I need to run that other stuff?? Will I need to use my computer to tune??

You could run hondata and tune specifically for your application, they even have a system specifically for turbo applications or you can get the regular s200 system. Also I am curiose about your first post, you say your going to be switching to an external coils, but we already ahve external coils. Why not just run an internal one .

www.hrtuning.com/ here ya go!
http://www.hrtuning.com/rtpsoftware better yet!

[Bglad420]

To legend masters Q, everybody says that they don't last, or else I would prefere to keep the internal, which I still might.

To 89 Turbo--Thanks!

[Bglad420]

SO I would need to buy one of those boards??

What is your definition of last. The external coils go out to, but I cant say that they last longer then an internal coil. Plus I believe you have to get some sort of MSD box to run external coil on obd-1 (not 100% sure on this one, but you should look into it).

[89T]

all he needs is a blaster coil, and a msd cap. or https://www.3geez.com/forum/showthrea...283#post721283 post #2

[Bglad420]

I'm still kinda confused about what to use for my tuning.. I would need to buy that board, but which one?? What are my options for that other companys, do you have links for them?? Sorry to be so dumb about it but I have no idea really, I thought all I needed originally was the ecu, dizzy, harness's, and controll it with an AFC, but now that this new to me info has come up I would like to get what is best.




I should have a MOD change the title to My OBD-1 Conversion retarded questions.

[89T]

SO I would need to buy one of those boards??

yea! for neptune.
same board just a bunch of diffrent pic's of it. witch ecu's are compatible? http://www.hrtuning.com/pages/category/compatibility/
alot of the pro's are running this now.

for chrome, handata, turbo edit, i belive you need a rom burnner, to burn new chips. this should help if you want to run one of these.
