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.
Throttle Index Table
Some vehicles use a table to calculate the index to the main throttle table.
This table uses vehicle speed for the row index and throttle pedal for the column index.
Target Throttle Plate
This table maps the relationship between the throttle pedal and throttle plate. The row index is rpm and the column index may be throttle pedal or the value from the throttle index table. The throttle plate is opened less at low rpm for smoothness.
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
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.
Overrun throttle
Upon overrun the throttle plate is held open slightly.
Minimum throttle opening compensation
This table adjusts the throttle opening upon overrun by coolant temperature
Settings all values to -100% will disable the overrun throttle opening.
Throttle Flow
In some situations the ECU will need to know the air flow past the throttle body for a certain throttle opening.
This table only needs to be altered for larger than stock throttle bodies.
Throttle Tip In Fuel
The ECU will add extra fuel when the throttle is opened quickly ('throttle tip in').
Tip in fuel ECT compensation
Compensates tip in fuel for coolant temperature. A higher value is more fuel.
Tip in fuel throttle compensation
Compensates tip in fuel for starting throttle position. A higher value is more fuel.
Injector Overrun Cutoff
The fuel injectors are shut off during overrun conditions (deceleration with the throttle closed).
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.
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.
