I will go off the sheet below for this explanation
Boost timing (is in steps of current increasing and descreasing and will adjust as the rpm is advancing )
example if you use say 20 steps in boost but your running your car at a very low rpm well the speed controller is still producing 20 steps as programmed and that will in turn heat the motor and thats why we use dynamic timing at low rpm to avoid this occuring .
Turbo slope ( relates to how fast you want your turbo setting to ramp up in steps per time
Example: Turbo Timing is set to 24° and Turbo Slope Rate is set to 3°/0.1s, it takes 0.8S to activate this 24°Turbo steps.
Turbo timing (steps not timing) is the steps that you have available to adjust for the turbo effect and that all relates to steps in current flow increase/decrease and time .Also called additional steps that come into effect faster than the basic steps in boost timing as it work with time and not rpm .
Boost start Rpm (ESC begins to increase the internal steps of current when the motor speed reaches the Timing Start RPM. A Smaller Timing Start RPM value causes a faster rate of Timing because the ESC increases the internal steps of current flow earlier.
Turbo delay ( means when do you want the turbo boost effect to come into effect .the lower the setting the faster the turbo will be activated say 0.1 secs of delay it will take only this time to activate etc but remember will only work on full throttle .
boost timing acceleration ( as its called This refers to the RPM increment that triggers the Timing increase of 1 per step. The lower the value it is, the more torque the motor will produce but at the expense of the motor increasing in temperature .
