Just wondering if a wire spliced pgmIII is able to produce more power than a pgmIV hrc 030 card?
let assume the engine has all basic mods (pipes ,airbox ,reeds, stuffers, head conversion)

Is there any difference in the amount of ignition timing between them?
or are they both able to produce about the same amount of power

Hmmm something to ponder

Which bike do you have?

Had equal mojo from a well set up HRC 28 and a well set up (spliced) 21. The difference? Lots of money!

Both ignitions suck.

The NH3 PGMII is much better and should be fitted to all models.

Is this a straight swap for the PGMIII - or do you have to do some wiring "surgery"? What other mods are required, and what benefits gained? Just curious if my PGM unit dies, or I am looking for a replacement.

It's a direct plug-in, just so long as you change the wire harness, a few components, ditch the MC28 clocks etc etc.

To be honest, the MC28 was (for some reason) made difficult and expensive to derestrict, whereas the MC21 actually wants to be full power, but the Jap government put their foot down with a firm hand and said NO!

I've been playing with a programmable ignition on my 300 and it beat all the other's I tested against. That includes PGMIII (spliced), PGMII (spliced), F3 PGMII & NF5 PGMII. This is the way forward. Fully adjustable everything.

Biggest power gain wasn't so much the ignition timing, even though I was able to optimise it for the 300 motor and gain 1 hp over the NF PGMII at peak and a bundle either side, but it was the RC valve timing that really made the difference. Get that right and the mid range power just comes stomping in.

My 300 harness is not even a shadow of it's previous life as an MC21 harness, but I'm trying to suss out the 'plug-n-play' for MC21, and also trying to figure how to get it to work on the 28. But that's a little tricky thanks (NOT!) to the fancy electronics of the 28 clocks.

All said and done, best plan (for easy mojo) is to buy a 21 or 18, and then print out a pretty picture of a 28 to put on your wall.

Matt,

Yep, got 2 '21s. Was wondering about the advantages of using the RS pgmII over a stock PGMIII. I've also got an HRC '21 harness to play with as well. Fonty has also referred to using this unit on an NSR.

I realise this post may be better in the HRC section (for the mods).

Of course, developing your own programmable unit would make all this irrelevant, and negate the whole issue of discontinued stock parts.

thanks guys for your input,

i've been toying with an efi set up for my mc28 ,it's a long term project.
i planned on setting up a spliced pgmIII and logging its ignition curve through the rev range with a timing light and a cam degree wheel mounted behind the flywheel it would be the base setting for the efi, rpm activated outputs on the ecu for the power valves and exhaust sensors for the fuel.
i've spoken to some ecu manufactures and selected the unit i need

Matt are NH3 PGMII an obtainable part or are they a rare race part? it sounds like the unit i need to graph

NH3 PGMII's are in short supply. I've got a few, and a couple of the other usual suspects will have some hidden away. Not for sale though. I've hidden mine under a pile of hen's teeth.

Plotting the ign curve is a bit of a task. I wouldn't like to do it on the bike. I made a 'mechanical black box' to imitate the flywheel, so I can do all my NSR electronic testing on the bench. It's much less hassle than sitting there trying to hold the engine at a steady 11,500rpm while reading a timing light.

You'll find some very interesing curves while comparing open and closed throttle timing/spliced timing etc.

Hi Matt ,

Will this new pgm be for sale to us normal guys ?

It's already available. It's just not set up correctly for standard use on an NSR. The maker has some very basic settings to get it to run on an NSR, but doesn't know the RC valve timing, or solenoid timing. Probably because some sneaky git won't tell him

The original ECU couldn't control that much, but the latest one does pretty much everything I want and then some.

Like I say, just need to figure it all out to be a simple plug in.

I would be interested in one for my mc21 racebike ! Should i keep a look out on the tyga site or this forum ? Thanks Neal

any news on the progamable pgm ?
