My 2007 DL1000 came with the PC3 USB unit installed by the PO (original owner). Otherwise the bike is completely stock except for the K&N air filter which I only discovered after lifting the fuel tank to clean it. It hardy needed cleaning but I had to verify it's condition ... like new K&N.
After riding over 7,000 miles in the past year since purchasing it, (still only 16,250 total miles on the ODO) my impression has been that it runs very well except for an occasional hiccup just pulling away from a stop midway during a ride. I suppose the fuel mileage could also be better, ranging from a low of 32 mpg when on the throttle a lot, to a best of 38 mpg cruising moderately on the highway.
Looking to cure the hiccup and possibly improve fuel economy I have read this topic with great interest from beginning to end noting the fuel maps tailored for different model years and aftermarket modifications. It has been an education, and necessitated downloading and installing the PC3 Control Center software, then studying the user guide. Then I downloaded the fuel maps for the bikes most similar to mine, which include Cheff's OMG map, and his others, the Jett map, Shep's maps, those of the Criscokid, etc., to compare with the map installed on mine.
With the bike running the PC3 Control Center software quickly connects to my PC3 unit and it is easy to get a copy of the fuel map on it. Cheff's OMG map is supposedly for a K6 with the only mod being a K&N air filter, like my K7, so using the Compare maps feature in the Control Center software I put them side by side and get a big surprise! It turns out the maps are approximately parallel, with mine being the richer one hovering above Cheff's line across the rpm range and on the various throttle positions. WOW! ... By the way, with two maps loaded in the Compare Maps feature, select Difference Table and click on any Throttle position to see them illustrated on the graph across the top of the window.
My take away is Cheff's OMG map should give me better fuel economy since the fuel map I've been running is richer practically across the board. And as for the low RPM hiccup pulling away from a stop, my map shows it is extremely rich from idle to about 2,000 rpm, where Cheff's map is much flatter on the low end. This could be a remedy for the hiccup I've noticed. To bring this to a close, and I apologize for going on so long, I have put Cheff's OMG map on my unit and cannot wait to give it a try it as soon I can get a free afternoon with decent weather.
I would wholeheartedly encourage anyone who is not happy with their PC fueling to dig into this, learn what is needed, the tools are free, and go for it.
