Part of my job responibilities recently have me dealing with atv/utv repair, learning as i go. Yesterday was fuel injection issues, did a bit of reading...
Evidently variations of this type of injection utilizing a temp/pressure (t-map) sensor are quite common on 4 stroke atv's.
And it seems like many use somewhat standardized components.
Some are open loop and some are closed, really just a matter of whether or not they use a/f sensors.
And there are of course all manner of aftermarket devices available to alter the fuel and timing parameters ouside of epa mandates by replacing, or splicing into, the ecu. Some are simply flash loads.
So there are possiblities for the saw, though doubtful any time soon due to the relatively low production volume and smaller still number of those wanting to do performance mods.
That and because it's more or less open loop makes it more complicated to alter.
But all it takes is one programer that gets interested enough to give it a go...
