For example before the official release of the JB for M5/M6 vehicles, Terry from BMS had everyone use the 550/650 (N63) units and change the "user feature" and then that unit was then ready for M5/M6 application.
But now on his website the he lists the S63TU units separate.
Are we running the incorrect version if we were sold the N63 kits prior ?
Thanks for you time. You always answer very well for the BMS team
There are basically two board types used for the s63 Stage1. There is the G3 board and the G3_V2 board. The G3_V2 is the one that includes methanol support, fuel control, logs with the JB4 interface, etc. A lot of the stuff on there is not used for the s63tu (yet) but is used for the n63 Stage2. Most newer orders ship with the G3_V2 board and most older orders have the original G3 board.

Under firmware if your date ends with //3 it's the G3 board and if its //4 then it's the G3_V2 board.

Note these are both Stage1 boards and BMS does not offer a JB4 system for this platform.
