Ecu Question!!!

What ecu does an 89 Si have??? I have a chance to get a chip but it's for a Pm6 ecu. Is this my ecu??? I really need to know!!!

Yes the 88-91 Si's have the PM6 ecu. The chip you want to get is the right one. The PM7 is the ZC ecu and the PG7 is the 88-89 integra ecu.:)

yea that is your ecu. Im running the PG7 ecu right now(88-89 Integra) on my ZC motor and that's the best one for that motor. :D

Besides the PM7 with the speed limiter removed..lol;)

very true :D

Do all 88-91 crx's have the Pm6 or is it just the Si's??? Like what ecu does the Hf and Dx have???
Thx

The HF's have the: PM8 ecu

I have no clue as to what the code is for the dx.

what would be the best ecu to put in my 84 crx, aftermarket wise? -Thanx:confused:

4th Gen DX's have the PM5 ECU.
