Throttle Modulation

 

The throttle movement can be adjusted to open on a different value than the pedal set point. This is handy when large throttles are used. Then when it is used in town you can select more pedal movement than throttle movement which will make the car more drivable or the pedal less sensitive. Then on last movement to full throttle, the throttle will move more than the pedal and give the extra power required.

 

Select the Show Graph next the TPS selection.

 

 

Click on the TPS Graph TabSee the graph below. The X Axis is pedal TPS movement and the Y axis is throttle movement set point. The range is from 0 to 100. -50 is 0% and +50 is 100% throttle. If Show Graph is off then throttle movement set point will be the same as pedal TPS %.

 

 

After setting, make sure the throttle can move over the whole scale range. Note that Low Limit Duty Cycle will cause the throttle to not go to 0% but remain it idle %. You may start the graph at a higher value than -50% so that the throttle moves more instantly when the pedal is pressed. Make sure not to set it too high, as it will then overcome the min duty cycle and the engine will idle faster.
