I'm interested in doing this conversion so I can run the AEM EMS computer. There are two questions I need answered first.

1. I'll be using a OBD0 to OBD1 conversion harness. Can this be used with the OBD0 (i.e. stock) distributor? I know the timing wheels have different tooth counts but the EMS can correct for that. If I can use the stock dizzy, can someone outline what I do with the extra wires in the conversion harness that are there for the OBD1 dizzy?

2. If I indeed do need to run an ODB1 dizzy, which one will bolt on to an A6 head?

Thanks.

 

It sounds like you are tryin to use an OBD0 DPFI distributor if you have 2 extra wires OBDO-OBD1 MPFI have the same amount of wires.

Might be able to try an OBD2 distributor but I can't remember what year they threw the Crank angle sensor in the oilpump housing that might not have been until 1999. I really can't remember.

 

steve, are the answers not here?

Keith,

That link still did not answer the root of the questions. When you use an OBD0 -OBD1 harness, there are several extra bare wires that you solder up to the OBD1 distributor. Many people say you can just stick with the OBD0 dizzy if using the AEM EMS. That's fine, but what do I do with the bare wires coming out of the conversion harness???? Do they just get left not connected to anything?

Any difinative help on that question is greatly appreciated.

Thanks.

 

fyi, you might get a better/quicker response on AEM's forums since this seems EMS specific...

 

Tried that. They don't know much about conversion harness issues.

 

There are no extra wires for an OBD0 abd OBD1 distributor. MPFI OBDO and OBD1 both have the same amount of wires running out of the distributors. Even the plastic connectors are interchangeable by depinning them except for the 2 wire connector. I have built multiple harnesses for MPFI-DPFI, OBDO DPFI -OBD1 VTEC etc. I think those extra wires are there for the VTEC oil pressure switch and spool valve that you are concerned about.

 

****! Your right. Those extra wires are not for the dizzy. I was given some incorrect info that stated they were. I confirmed with the harness maker than the wires are for other stuff (vtec, cel, etc)

 

You should IM Blown90hatch, Jason's his name. He made my OBDO-OBDI harness. the extra wires are for the 4 wire O2 sensor and the VTEC wiring. Jason could tell you better than I can. Oh yea, And if you go to OBDI you must change the dizzy. They are complety incompatible.
HTH

 

have to contacted one of the OBD-converter KINGS like blown90hatcH?

 

To run an odb1 conversion with the aem ems, you do NOT have to change the dizzy, just change the info in the aem software from 24 tooth crank sensor to 16, along with other things. http://forum.aempower.com/bbs/viewtopic.php?t=1780

 

Word! Now I'm all set to do the conversion.

what are the pros/cons of changing from obd0 to obd1 on d16a6? i would like to know....

Well, I'm in the middle of doing it. So I would say the cons are, "doing it"
in the first place. LOL and that it's a PITA. But those are about the only cons I can see. All the rest are pros.
And I would amend the PITA comment, because it's really only a PITA if you you have to go from dpfi to mpfi, at the same time. If your car is already mpfi, it's not that big a deal.

 

for the peeps that are done doing this.....let me know pros and cons......thank 4crx4me for your feedback....but i still want more input....

 

Well some more pros are that OBD0 parts tend to break easier or more frequently, or so I have heard. LOL OBD0 parts are older therefore getting to be harder to find in good condition. The sheer quantity of OBD1 engines and parts are another plus. As Katman said on a similar thread a while ago OBD1 is just better technology. Better, more accurate dizzy control. Better more accurate ECU control. Easier to update software and will accept free standing engine management. Easier to modify and upgrade than OBD0. Compatible with Hondadata. And much easier to swap in a newer engine if you decde to go that route. OBD1 engines produce more power than OBD0 engines that are otherwise the same. PM Katman if you want to know more, he's my OBD1 guru. LOL

thats what i wanted to hear......i think i know what my next mod is going to be....

 

For me, the whole reason of the swap is to run the AEM EMS. They don't sell one for OBD0 cars. The AEM EMS will be the foundation for future projects like individual throttle bodies.

 

steve ITB's would be really nice......keep me posted on that project.....
