Transient Throttle Disenrich
The rate at which fuel disenrichment is applied in response to a lift-off transient throttle event. This table is used to proportion the amount of disenrichment based on the rate of closing throttle movement and the throttle position you were at when the movement began. Up to 3D mapping is available.
This table sets how much fuel is removed during a disenrichment transient event (lift-off), and multiplies with the Disenrich Rate table to give a final amount. Typically mapped over RPM. Typical values are 25 to 50 at low rpm, 100 to 200 for high rpm. Although not true VE, the numbers are a VE approximation where larger numbers will give more fuel disenrichment, and lower numbers will give less fuel disenrichment. Up to 3D mapping is available.
What is Transient Throttle ? Transient Throttle is a fuel correction function used to compensate for an opening or closing throttle body. As the throttle is opened and air enters the inlet manifold there is a period of time where the manifold ...

Transient Throttle (Throttle Pump) Explained
In this article we are unravelling one of the mysteries of tuning; the often talked about but rarely understood dark art of tuning the Throttle Pump, or as we call it here at Haltech the Transient Throttle Enrichment function. Transient Throttle If ...
Transient Throttle Enhance
The manifold pressure sensor used with the ECU is very fast. It can respond much faster than is required to track any sudden changes in load on your engine. However, the manifold pressure seen at the sensor input may not change as quickly as what is ...
Transient Throttle Enrich
Enrich Rate The Enrich Rate table is used to proportion how much of the Enrich Amount tables are applied. This calculation is based on the rate of sensor movement while opening the throttle (X-axis), and sensor position at the start of the movement ...
