I have a pm6 now that must be a 88 or 89 because it doesn't have the right chip. Do I get a 90-91 from a si or will any 90-91 ecu work?(including non mpfi) Are some better than others and does anyone know the rest of the code I am looking for? pm6-? I want to put a vtec head on later also if that matters, I just dont want to buy the wrong one thanx in advance, Chad.

 

Your best bet is a 90-91 PM6 if you're not going VTEC, and a 90-91 PS9 if you plan on doing VTEC.

There are a lot of other options, but those are the two most common.

 

What did the ps9 come in?

 

PS9 ECU = Automatic SI...years 90 & 91.

 

Actually automatic EX 4-door

 

Whys it best for the PS9? Can you control the vtec through it. Ive gone the PM7 route with vtec off a rpm switch

 

i dont think there is a such thing as an auto SI. but i might be wrong

 

Any updates on VTEC developement?

 

Single Map VTEC is stated to work now..

Dustin doesn't use TE anymore, so he's unable to test for us.

A ROM coder named Tatou on PGMFI fixed the VTEC code and stated he tested it with a test light, and on a D16Y8 motor.. VTEC engaged as set directed by the users TurboEDIT options.

I would like to get more tests to make sure...

..anyone with a PS9 want to test?

 

but due to the ps9 ecu the maps are limited to 7400 rpm are they not?
