this ecu comes in the 1990-91 "US" civic ex automatic. or you can call it an automatic pm6.the advantages are its T.E. compatible and has the extra 12v output to drive the vtec solinoid which the pm6 does not.pwo/pr3 are not T.E. compatible for boost.

Can you use the PM4 from the 90-93 tegs with an automatic ? The PS9s are hard to find.

I haven't heard of that ECU..

Give it a try, and let us know.

Sorry I don't know what the numbers are for the ECU in the 90-93 teg with an automatic tranny. I know the 5 speed motors have a PR4, but will the ones from the automatic cars work the same as the PS9. Like I said the PS9s are hard to find.

Well, if it's a USDM 90-91 Integra (92+ is OBD1) Automatic, it would still be a PR4.. manual or automatic.

There are a few bits of hardware to remove to make it manual, I think Chris would know more on that.

..but, no, from what I am aware of, the USDM auto PR4 (OBD0) will not work "as a" PS9 would.
