which tegs have OBD 1 ECUs? OBD 2? is there such a thing as OBD 3?
is it true that OBD 1 puts out more power than OBD2?

thanks

 

Try http://www.HASPORT.com they have a list of all ecu's there check it out!

 

obd 1 94-95 and obd 2 96&up. No such thing as obd 3

so is it correct that OBD1 responds better to mods then their OBD brethren?

 

glad you found it sorry about the delay!

 

Why does my '01 GSR have a p28 and not a p72?

 

If that is true then you will not have the extra circuit to open the secondary intake runners when VtEC is enabled.
Just get a Skunk2 Ecu since they only have the long runners and not dual like the GSR's.

Did you buy the car used?

No, it is 6 months old. It seems Acura may have F---ed up at the factory.

I think I'll check with the dealer Monday.
