Dave, you are a cunning boy! Do you still use one on the throttle, I suspect not?

The fueltech has a programmable mixture table table to be used with a throttle position sensor(TPS) which is simply a potentiometer. So simply mount a potentiometer, tell the fueltech it is a TPS, and adjust the TPS mixture adjustment map to your liking. There you have a manual mixture knob.

In fact, the EC-2's Control board returns the voltage of its 5K ohm potentiometer so I hope to simply use that one which is already mounted.

It is also possible to use the micro switches in the EC2's control module to activate almost anything you want through the fueltech.

Jeff,
Yes it does and also mandatory is a throttle position sensor.
But no it does not have a manual mixture knob. For that reason if needed
thew only current answer is the SDS.

Hi Neil, does the Fuel Tech allow for open-loop operation like the EC2?
Does it also work without a Mass Airflow Sensor like the EC2? Jeff
