PR4 : 92-93 OBD-1 Integra B18A1
If it is the OBD0 one I would skip it, but if it is OBD1, follow the following.
Here is the auto to manual conversion:

And here is the VTEC Conversion, if needed:
First buy the right kit-

Then follow the appropriate link for the kit-

And of course the chipping:

That should get you going. It's a bit of work, but it is worth the money savings if you can solder fairly well. I do recommend desolding braid. It is amazing. But upgrade your soldering iron if you are using a $3 one from Walmart. The $15 you can find on amazon or somewhere is much better.

If it is OBD0,
Seems hard to find information on converting. And it seems like it doesn't work well on the OBD0 ECU. You still get a CEL code. HOWEVER! Let me say, I can disable CEL codes very easily with a chipped ECU. I know it doesn't solve the problem, but I think the CEL is the only problem you would have.

I have a chipped PR3 ECU that may help you if you want it. I don't have my chip burner anymore. Maybe I can get a deal on one and hook you up with a new chip. Either way, answer my original question about the PR4 first.
Lemme start off by saying I have done multiple searches on how to convert a obd0 PR4 auto ecu to manual both here and at pgmfi.org and haven't come up with any specific answers. Well my question is if anyone knows what exactly needs to be removed and or jumpered to make an auto obd0 PR4 ecu to manual without throwing a CEL. I have both an auto and manual ecu sitting in front of me and I was expecting to see two or three differences but when I look at the board I see at least 10 or more differences between the ecu's. The reason why I don't just use the manual ecu is because I have a 91 and the PA sensor is internal and the manual ecu is throwing a code for it while the auto is not. However I have a 5 spd obviously so the auto throws an EGR code. While I was searching thru sites I remember reading something about most "mugen" ROMs disable the search for auto hardware, so would chipping my ecu with a "mugen" ROM solve my problem on the auto ecu? Anyone who has converted from auto to manual by converting their auto ecu to 5spd please respond. Thanks in advance.
