So for software; I imagine I use “508_no_timing” for 17.5 no timing and “528stock” for 17.5 open and 10.5?
As for which ESC: What is the difference between the GT2.1 Prostock (EXT98802PROscb) and GT2.0 LPF (EXT98802LPFcb)?

Correct...508_no_timing for limited ESC spec and 528stock for OPEN speedo for 10.5, 13.5, 17.5 and 21.5.
GT2.1 ProStock has a aluminum case design, better way to destribute heat then the GT2 LPF version...GT2.1 ProStock is a newer model tehn GT2 LPF..GT2.1 ProStock also use a 30mm fan instead of the LPF use 25mm fan.

Yes, correct...and we are currently testing the new software specially designed for indoor carpet, TC and 12th scale with lower rpm engagment range which Josh Cyrul has been testing. Once they are ready to release, you will see that on Speed Passion website. EX is the ESC that you want for 12th scale or 10th scale WGT.

Yes, correct...you need that to upload future software onto the whole GT series ESC that you own....
