Define "difference".

Early (87/88 ish) F3 electrics are called "pre-PGM" and are similar to early RS in that the CDI and RC valves control boxes are seperate. They cannot be plugged into a normal NSR setup unless you have the entire CDI/RC box/coils/adjustable stator (which requires the F3 cases and crank) etc.

Later F3 stuff was PGM-II and the PGM looks exactly the same as a mk-II mc18 or a 91/92 RS. It even plugs in and works on a normal mc18 mk-II loom (as does the RS PGM) but you need the engine work for it to make better (or even the same) power.

To elaborate on what Fontyyy said. The PGM started in '87 on the MC18, but the F3 version used the CDI from the RS. '88 MC18 went onto the PGMII. We know the story after that.

As for differences, there are many. As in what they monitor and how they control the ignition timing and RC valve operation.

NF5 PGMII differs from the NH3 PGMII in timing and RC valve timing. There's also wire snips that can be done to alter the timing further. The NH3 PGMII offers one wire snip, the NF5 offers two snips.

I've done a fair bit of bench testing on the PGMIII and it monitors many things such as RPM, gear position, throttle posistion and throttle opening speed. The ignition timing, RC valve control and solenoid control are all controlled by these. Then you "wire splice" it and change it all completely!

For your info the stock PGMIII, spliced PGMIII and NH3 PGMII are very different in ignition timing.

Thanks Matt and Fonty. I was after the differences in what the various PGM's do (ie, I, II and III).

PGM-CDI (commonly called PGM-I) is 1988 MC18R-J, PGM-II is 1989 MC18R-K, PGM-III is '90~'93 MC21, and PGM-IV is 1994~ MC28.

A complete PGM-I setup (including flywheel) will be the easiest to implement on an MC16, and optimised for the better porting, pipes, and carbs/air correction. The MC16 kit is designed to give 45~50hp, and that's about it. No matter what you do the MC16 electronics will always hold you back.
