I have been reading about the DPFI to MPFI swap on many forums. I'm wanting to convert my 91 civic lx over to MPFI, but I'm unsure if it will work with an automatic transmission. Is there a specific ecu I would need to do this or will any pm6 ecu work?
Thanks

You're actually looking for a PS9 ECU to use MPFI with auto tranny... that's the only OBD-0 that I know of that will still allow your tranny to work properly.

I have one, and I ship. :)
