R32 / B32 Tuning Tips
Below are some tuning tips to maximize your ORCA R32 and B32 Electronic Speed Control.
Here are some quick notes on the various setting options for top performance.
**Some features described are not available on the B32 'Blinky Only' Electronic Speed Control as they are timing/boost features but can be found in the R32. Consult with your user manual to find the specific features/setting enabled in your electronic speed control.
1) Punch – Allows you to change the punch of the ESC (Level 1 to Level 15):
- Level 1 has the least punch and Level 15 has the highest punch.
- Adjust punch level to maximize acceleration speed with minimum wheel spin.
2) Pulse Width Modulation (PWM) (This function can be found in the "Advance setup" except Blinky mode) – Allows you to change the forward drive frequency of the ESC (2K to 32K step by 500HZ)
- The 2K setup will give you good punch at the low end.
- The 32K setup will result in strong mid to top end.
- Experiment to find out what suits your driving style best.
(Lower PWM will lower ESC temperatures while higher PWM settings may increase ESC temperatures and Higher PWM will course ESC more heat.) Ensure that your physical wiring configuration of A-B-C match Initial Setup options of the Program Card.
3) Drag Brake – Also known as trail braking - allows you to set the automatic brake force applied when the throttle returns to neutral position (30 steps from 0% to 30%):
- Drag Brake affects how a car handles off-throttle (entering a corner). With drag brake on, there will be more weight shift to the front tires thus increasing the front-end grip when you let go the throttle.
- Experiment with different settings to find the setting that fits your driving style.
4) Compress (found in "Advance Setup" menu, Except for Blinky mode where it can be found in "Quick Setup") - This is for throttle curve, the higher the number, the more responsive the throttle feels at bottom end. 0% is linear throttle response. That's mean throttle compress, than will course you more sensitive in the throttle bottom.
5) Timing (Except "Blinky Mode") – Allows you to adjust the timing of the motor (0º-100º Mode 1º increments):
- Generally speaking, in brushless systems, an increase in timing will result in an increase in the RPM of the motor. However, increase in timing can also decrease the efficiency of the system, thus generating heat on the ESC and motor.
- Lower timing has the most torque and the lowest RPM; Higher timing has the least torque and the highest RPM.
6.) Turbo Timing (Except "Blinky Mode") – Turbo Timing is unique to brushless systems because the ESC can simulate motor timing advance. While mechanical timing advance in a brushed motor system is limited by the physical phasing of the motor, brushless ESC timing advance can push beyond that physical limit. As a result, motors can run at a super-high RPM in the Turbo Timing mode, resulting in a sensation of having a 2nd gear/Turbo for top speed. This menu allows you to adjust the amount of Turbo Timing in your ESC in 1º increments. (The “Turbo Timing” should never be greater in value than Timing)
7) Turbo down rank (Except "Blinky Mode") – This is an opposite side Turbo timing for braking, preset -15, if you set the value to -30, this will smooth the throttle response as you slow from top speed, if you value set to -1, this will have more drag brake effect when you release throttle from top speed.
1) Punch fine tune – Allows you fine tune your Punch setting more detail, if you set (+1) your punch will up to 7.1 when the punch setup is 7, if you set (-1) your punch will down to 6.9 when you setup is 7.
2) Timing start – Allows you to adjust early or later to add timing in bottom power, this will make it easy to get a smooth power band in bottom power.
3) Timing range – Allows you to adjust a smooth power band in middle power.
4) Turbo delay – Delay how long to start your turbo timing when you touch the throttle turbo point.
5) Turbo timing – Turbo Timing is unique to brushless systems because the ESC can simulate motor timing advance. While mechanical timing advance in brushed motor system is limited by the physical phasing of the motor, brushless ESC timing advance can push beyond that physical limit. As a result, motors can run at a super-high RPM with the assistance of Turbo Timing, resulting in the sensation of having a 2nd gear/Turbo for top speed. This menu allows you to adjust the amount of Turbo Timing in your ESC in 1º increments. (The Turbo Timing value shall never be bigger than the Timing value.)
- Turbo Timing is applied at 95%(preset) throttle.
- Higher Turbo Timing settings will increase top speed, motor and ESC temperatures as well.
Caution! Always monitor motor and ESC temperatures closely when applying timing to the ESC or motor. Heat may build up very fast in both ESC and motor and may cause permanent damage to equipment.
