I've released firmware v2.2.2 to the github repository. The change log is as follows: 2013-01-11 2.2.2 Firmware 2.2.2 #94 v2 firmware re-work for multiple vehicle support #95 Valet Mode - Tesla Roadster - Trunk open is working off bonnet #96 Server: Support for historical data messages #97 CAN overflow (lockups) #99 Update vehicle/Car Module/VoltAmpera/voltampera_canbusnotes.txt #72 #72 Add GPS support for cars without it ### v2.x firmware, first release Internal GPS integration Basic support for Renault Twizy Volt/Ampera work-in-progress Framework sprintf rework First draft of OVMS Development document Twizy user guide v1.0.1 The .hex files have been built for all configurations. I (and others) have tested this in hardware v2 vehicles, but so far this is pretty much untested with v1 hardware (in particular for Tesla Roadster). I would appreciate it if you guys could test it and make sure it is ok for v1 hardware in Roadsters. Once you upgrade firmware to v2, you will need to either (a) SMS "MODULE" command again to include the fourth parameter vehicle type "TR", or (b) use the iOS App to set feature #14 to "TR". You will require this for the CAN bus stuff to work. I have updated the Tesla Roadster user guide to reflect this new parameter. Regards, Mark.
