What exactly does it do besides do the opposite of positive timing? does it add torque and lose top speed as positive timing adds top speed and loses torque?

Technically speaking, you cant have negative timing or the motor will not work. You must have some timing advance on a brushless motor for the rotor to move.


Now having less timing advance will give you more torque, and a higher efficiency. (Less heat). But more timing will give you more rpm and create alot more heat.

From acouple of dyno tests, brushless motors dont seem to really lose alot of torque when you have alot of timing (17.5BL), but gain huge amounts of RPM, making alot more power.

The whole idea of boosted/turbo was have alittle timing advance at low RPM, creating the extra torque, higher efficiency (lower heat), and then as the motor started to top out, you add more timing advance to bring the RPM up.


Hope that helps,

Shawn.
