Max internal should be 125C for x12's

External temp is useless mostly as the forward facing side could be 10c different due to cooling. If you left the motor a minute for heat to soak you'll probably find its 30c lower than internal temp but It still doesn't tell you what instantaneous heat there might have been.

Depends on the motor really but I think setting the cutoff to 120 for an X12 is acceptable.

when I check the internal temp with the telemetry. it shows 109 Degrees celcius when I was running at 24 timing... After I have changed the timing as Martin suggested, to 20 and the temperature stayed at 109 after 5 min. I also notice that After about three minutes the car get a little slower than the begining!

That sounds typical of heat protection setting kicking in, mostly amp limit in "if excess temp" setting. Put shut down temperature to 125 and limit current to 40amp in "limit if excess temp" setting. Set cut off temperature motor to 115.

If its still throttle down with those heat settings then you're still too hot and you'll have to back of timing some more. Run x12's with minimum timing 4 dot insert and around 6.2 FDR

How much timing are you runing ?
Do you run a fan ?
How hot's 'quite hot' ?

Turn the software timing down also. You should think of 20degree as you maximum for the x12. Keep dropping timing down until you are not going any higher than 90-100c. Then stick a bigger gear on it and see what happens.
I found when you find how much timing you can use, because of temperature, you then just keep putting on bigger pinions and temperature doesn't seem to move.

How-to from Martin states that 25 should be the highest value.

Thats 30 degree software and assuming you have the minus 10degree insert in thats still another 40degree fixed timing. You must be running long straights!

GM made easy – V13.0

Since I wrote the last tutorial quite a while back I feel like with V13.0 it is a little outdated.
So here is a new one.


Download V13.0: http://www.gm-racing.de/rwdownload/index.php?dl=154
This Tutorial bases on the file: V13_basic.gd2
I MESSED up the Transmitter data so please note that if you copy this file onto your speedo you NEED to redo your transmitter setup (-> pick the mode via transmitter).
When properly done, the full throttle value should be something around 1.9ms, neutral between 1.4-1.5ms and the full brake value should be around 1.1ms.

With this file there are only 4 values that you change according to the motor / class you race and the track you race on.

1, Amp Limit

For any kind of Stock Racing (13.5/17.5 or slower) 80A is by all means enough. Most drivers actually prefer even less. In regular racing you actually not really reach that value anyway and in the cases you do reach that anything above 80A only creates heat instead of power.

For 10.5/6.5 the Amplimit should be 130 – 150A
For Modified (5.5 / 4.5) 140-180A is the desired range

2, Switchpoint RPM

When racing Stock I usually prefer not to use a switchpoint (Reserved 4=1). But this requires really smooth throttle control sometimes so in the sample file I enabled the switchpoint (Reserved 4=3) and set it to 10000 RPM. Anything Less is pretty much pointless.

Note: The LRP X12 requires a switchpoint to start properly! (different sensor position)

For 10.5/6.5 the switchpoint should be between 15 – 25000

For Modified 5.5T 25000
4.5T 35000

3, Fixed Timing / Max Timing

Fixed Timing handles the power! The value for both Fixed and Max Timing can only vary between 0 and 30! Max Timing values above 30 will disable the Max Timing feature!
Max Timing is only use when the launch control has been activated ( no throttle input for atleast 5 seconds). So you can have that extra bit for the start.
I always set Max Timing to Fixed Timing +1 as a general rule.

I know that people tend to overdo it with the timing values so here is what should be the highest values:

Graupner / Corally 13.5: 25
GM 13.5T: 24
LRP X11 13.5: 29
LRP X12 13.5: 20!!!
Speedpassion 13.5: 25

Modified (GM) 5.5T: 15
Modified (GM) 4.5T: 12

4, Motor Cutoff Temperature

The Tempcheck Feature only works with GM, Graupner, Novak, LRP X12 and Corally Motors.
Speedpasson and LRP X11 do not feature a Temperature Sensor so be carefull not to blow those up.

Values for various motors:

GM motors: 115C
Graupner / Corally motors: 125C
Novak: 115C
LRP X12: 120C

That’s it.

What if:

-The Motor gets too hot: gear harder / use less fixed timing
-The Motor is running cool but there’s not enough power: gear harder / use
more fixed timing
-The Motor feels slughish but temps and power are ok: you are overgeared
(although you really need to gear superhard to reach that point! (indoors
around 4.2 with 13.5T)
-Not enough brakes with LRP X11: update to V13.0 and set Reserved 4 (in
the telemetry tab) to 5 (if you used 1 ‘no switchpoint’ before) and 7 (if you
used 3 ‘HST with switchpoint’)
But with the basic file posted, there should be enough brakes as this has
been set already.
-Sudden loss of power: clean the motor and especially the sensors, check
the senor wire and the magnet

Basic Tips:

-A fan is always better as it enables you to run more timing
-Always make sure your motor is really clean

LRP X11:

-Set the Motortiming to 3.2mm
-Change magnets regularly as the tend to fade which generates more heat
and less power
-The motor can handle up to 130C. You are save up to around 110C.

Yes I have set it to 20 but I think I have to go lower with timing. I will give it a try and let you guys know what has happened.

Too high, drop it down to 25 fixed timing and 26 max timing.
