Throttle parameters

Top  Previous  Next

Warning: These are advanced tables. Do not change the values unless you are sure you know the effects of your changes.  Incorrect settings could result in the throttle not responding normally, with sudden vehicle acceleration.

 

Target Throttle Plate

This table maps the relationship between the throttle pedal (column index) and throttle plate by rpm (row index).  The throttle plate is opened less at low rpm for smoothness.

 

throttle-targetplate

Note that the throttle plate first column values are restricted in order to ensure the throttle plate closes when the throttle pedal is released.

 

Throttle Parameters

 

Throttle dampening

throttle-parameters

The standard ECU will slow the throttle opening when in first gear with the vehicle moving, which may result in a jerk once the throttle opens fully.  This may be disabled.

 

Injector Overrun Cutoff

 

The fuel injectors are shut off during overrun conditions (deceleration with the throttle closed).

 

throttle-overrun-rpm

The restart rpm determines at what engine speed the fuel injectors will restart operation.  There are two tables to set a hysteresis - the injectors will be switched off when the engine speed is higher than the cut table, and switched on again when the engine speed is below the recover table.

 

throttle-overrun-map

Manifold pressure is used to determine when the injectors are switched off.  There are tables for both the low and high speed cams, with hysteresis.
