Boy, there sure is a lot of discussion going on here. And the program can be very confusing, and like most any computer program, will get easier to understand the more you use/play with it. I'm Going to remove my side cover, and get the number on my ECM, just to see. I've used TuneEcu to open my secondaries 100%, and raised the rpm limit a tad, and the top speed. Lowered the cut in for the fan a touch, and tweaked the speedometer error setting. However, I've asked before, and haven't seen an answer YET. "Do any of you have the map that comes on the unrestricted 2013/14 Rockets?" There are so many different maps on the TuneEcu site, and from what I can tell, most are maps that have been customized by users. I'd like to see the factory unrestricted map, to compare to the restricted map. No offense, but I know someone will say, "well all they did was change this to that, so on and so forth", but I'd still like to see the real deal.
BTW, the last part of my VIN# on my 2013 is: 46DJ563191
