In the folder where u downloaded the 13.1, there's an instruction manual. Apparently it's only new brakes:

New brake functions of version 13.x compare to V12.x:
The new brake functions will give you a stronger brake feeling than the older v
Setting is on the flag Telemetry:
Reserved 4 (Value3) = 4 activated: the brake frequency will be devided /4 (f.e. a
brake frequency will be 1kHz). The result will be a stronger brake feeling.
Reserved 4 (Value4) = 8 activated: the brake frequency will be devided /16. The
than value 3, but stronger than the older versions.
Reserved 4 (Value5) = 16 activated: brake feeling like very first generation of GM b
brake feeling is softer, but may give a better brake feeling.

Reserved 4 (Value1) = 1 need to be still activated for the High Speed Timing.

Hi has any one run the GM with a Speed Passion 17.5 & 13.5 MMM series motors?

Would like some gearing advice for a technical 25m x 14m (80 x 45) carpet track?

Many Thanks

I ran it with the normal 17.5t, followed martin's setup for sp 13.5 motor was coming off at 55deg. Geared at 5fdr.

Default GM75 & Speed Passion 17.5 & 13.5 MMM Series

Hi I have run the MMM 17.5 and 13.5 with my GM 75 tonight for the 1st time

I couldn't seem to get them both below 90c!

17.5 set at about 15 Deg on the can and geared at 4.7-5 and a mild speedo setting (Mode 7 and Max Timing 12!)

13.5 set and 11 Deg on can and geared at 5.4 again with a mild profile (Mode 7 and Max Timing 12!)

Anyone got any gearing suggestions and speedo settings for the GM?

Many Thanks

With the SP v3 I used to aim for a max temp of 70deg. At 80deg you could feel a bit of drop off. So you're not miles too hot, it probably just needs a bit of tweaking to get the heat down.

I would start with minimum endbell timing. I think the extra timing on these new motors is mostly for tamer ESCs like the SP/Hobbywing. With the GM you don't need lots of endbell timing.

You really need the PC interface to optimise the GM properly, so the following advice relates to the settings available there...

Start off with Martin Hoffers settings file and read his guide (if you haven't already done so):

http://www.rctech.net/forum/7908081-post1851.html

Switchpoint RPM. Using one will lower the temps. I run 15k for 10.5, so would think maybe 12k for 13.5 and 9k for 17.5 would be a starting point.

Variable dependant timing. Again this will reduce heat by bringing the timing in gradually.

Current limit. On 10.5 I run 80A and have enough punch to spin the wheels (on tarmac). Any more than this and you're likely just creating heat rather than power, so I'd go for even less for 13.5/17.5.

Run a motor fan; I fitted a big 40mm one and this dropped the motor temp 10 degrees.

For 10.5 on a medium sized track (40m straight with some tight corners) I gear at 6.7. For a larger track (say 50m with flowing infield) I'd gear at 6.2.

For 13.5 I'd just gear up a couple of pinions (48dp). For 17.5 I'd then gear up a couple more.

Timing wise I then run the maximum I can, keeping the SP motor below about 70degC and the LRP x12 (which is my preferred motor as it has huge torque) below about 90degC.
