You can look up the part numbers online. Even Nissan dealers don't seem able to flash the firmware, so check if it's a 110, or 160KW inverter version. Don't believe the lies some of the VCU resellers are telling (about the Thunderstruck, Resolve etc.), you can't override the firmware limits. Some people have 'conditioned' the phase current signals to under-read and then re-mapped the torque commands with a CAN bridge. All limits are off if you use the openinverter logic board, but there isn't a bolt-in version yet (there is for Gen1 and Gen2), you have to make your own adapter board. The openinverter code improves all the time, but I'm not convinced it's quite as smooth, or quite as efficient as Nissan's algorithms are. Not far off though, Johannes is the main developer and drove his VW Touran conversion over from Germany to the UK last year to attend Fully Charged Live at Farnborough. He came up for a visit and the Touran drove impressively well.
