DYNOTECH Jim's post on H.C.S. Friday:
Still waiting for cold weather for further leanout, but right now we're using our 50 degree F 2010 D8 maps for stock, SLP, DynoPort, BMP exhaust which will be preloaded into the PCV before shipping.
old PCIII maps will not download directly into PCVs---there is an extra step in throttle position which can be manually interpolated, and I've done that for the excellent PCIII D7 maps we used last year and am doing that right now with the maps we created with Casey's 2010 spec sled. Updates and new maps will be posted on my website, easy download.
PCVs are $369 w/ free shipping in November, premapped
Autotuner kit for fine tuning and self mapping $250 additional includes Bosch wide band O2 sensor, weld on bung, and threaded plug so you can remove the O2 sensor after tuning is done (a few hours).
Polaris dealers please call for information.

The idea is to allow the autotune to tweak your PCV map to the desired A/F ratio for each RPM and throttle position, then remove it and plug the O2 sensor bung and you're set. It is feasible to leave the autotune on permanently and let it do miniscule adjustments on the fly, but that's surely not necessary once you have achieved the desired map.
Guys who are running basic setups, ie stock engines with various pipes etc wont need autotune because we'll create very good maps from the dyno and you can download those maps and be all set. We'll be doing only PCV maps this season, but PCIII owners can easily adapt V maps by typing them into their PCIIIs, in two minutes.
But if I was running a Dragon at higher altitudes I would opt for an autotune. We had lots of high altitude D8 PCIII users with our DTR flatland tuned maps, and were happy. But perhaps the autotune would make it even better, optimizing A/F ratio regardless of how the factory ECU compensates for altitude.
