Hi,

Just wondering if the PGM3 unit is the same through all models?
found one for sale off a '90 MC21R, my bike is '92 MC21SE are they the same unit?

Cheers

There are a couple of different model PGM-III's but they will all work on the stock MC21 harness.

Of the ones we have tested back-to-back on the dyno, there was NO discernable difference between them either.

There's a slight difference in the way the RC valve operates on (I think) the early '90 models.

I don't know if its the HRC cabling or the PGMIII but on my 1993 SP, the RC valves do not react as in the test description, can't remember exactly but they move the opposite way as described, when I remove the carb sensor, but they work normally during running.
