I know this setting changes how fast the boost is applied, but does this setting also shorter or lengthen the rev range ?
Could you recommend any settings for a mid to large outdoor asphault track with a long straight and a few tight and a few flowing corners?
And in the manual it says to never exceed 64 degrees of timing with the boost and turbo, but does this include motor can timing? Say if I had 30 boost 24 turbo and 10 degrees on the motor , would that be TOO much timing all together ?
Thanks
The Timing ACC dictates how quickly the boost timing is applied. It is 1 degree for every XXX RPM. So for instance, if you have 40 degrees of boost timing, 5,000 start RPM, and a 500 timing ACC, the timing will start adding 1 degree every 500 RPM starting at 5,000 RPM. So you'd have all 40 degrees of timing by 25,000 RPM (40 * 500 + 5,000).

The timing ACC does not limit the top RPM of the motor at all, it only dictates how fast the timing gets added. It can have a huge affect on the mid range and even low range power of the motor. However, going too low on the setting can easily bog the motor and create a lot of heat.

64* of timing is the max the ESC can apply, and it does not include motor endbell timing. It is common to use over 64* of timing total when you include the motor timing, especially in stock classes.

Temp is only high 30s celcius
You can easily add the max 64* from the ESC, plus some endbell timing on the motor. Your ESC settings and gearing will be important to not blow up the motor. Go to Speed Passion's USA web site and look at the team setups for TJ Lathrop and Robert Cooper for some good boosted 17.5 MMM setups.

It really depends on how hot "warm" is to you. Check it with a temp gun. It's best to run the fan if you are in doubt.
