Carpenter only supplies maps for Rockets in Tuneboy (at least for ones that go to 8 or 9000rpm) as far as i know, which are ECU maps. They have access to TuneECU versions of those maps now too though since i sent them on.
Power commander maps are effectively trim maps, since the PC3 or PC5/PCV is a piggyback module, they essentially only add or subract fuel or ignition timing from what your ECU does (based on the Triumph/TuneBoy/TuneECU map that's in your ECU)
People stick Carpenter's map in their ECU and then use a Power Commander to tweak the fueling etc delivery to perfection, because it's way easier and faster and every dyno guy knows it (unlike TuneECU and much less TuneBoy)
This particular map goes up to 9000rpm to compliment Carpenter's 9000rpm ECU map. For a while there guys were just using the 7000rpm PCV map with 8 or 9000rpm Carpenter engines.
It also has an ignition table that goes to 9000rpm.
Also this particular map has a lot more %TP columns so you get smoother transitions from cell to cell. It's much finer in terms of granularity
Following from above, a PCV map is only really a trim map, it doesn't have the full fuel/ignition value (amongst other things) required unlike the ECU map fuel tables.
If you have a PC3 map (.djm), you can import this into the Windows TuneECU, but not PC5/PCV map.
You can however import a PCV map into the Android TuneECU (since this app was continued to be developed after Alain stopped/froze development on the Windows one) but that is all - it wouldn't be the same thing as creating a whole new map etc i.e. PCV can't run an engine on it's own.
