Haltech E11/E8 Instruction Manual
The throttle pump setup allows the tuning of:
How much enrichment is needed for a given RPM, throttle position and TPS rate of change.
The biasing of the enrichment between asynchronous* and synchronous* according to a given RPM.
The speed at which the synchronous enrichment decays.
Note the rate of change of throttle position is how far the throttle moves over a 10ms time frame. A fast
throttle movement could have a TPS rate of change of 15% this means that in a time frame of 10ms the
throttle position moved 15%. A slow throttle movement could have a TPS rate of change of 1%, which
means that in a time frame of 10ms the throttle position only moved 1%.

• asynchronous enrichment (addition injection pulses) is where the ECU adds additional injection pulses
after the initial fuel injection event. Synchronous enrichment invloves the ECU extending the original
injection pulse – best results are achieved by using a combination of both synchronous and
asynchronous enrichment.
Throttle Pump Settings
• Max Asynchronous Pulses This is the maximum number of extra injector pulses that can happen
per injector output during an enrichment event.
Range: 0 – 10 pulses.
Default: 5.
• Throttle Deadband A rate of change of throttle position greater than this value will trigger an
enrichment event.
