No, the EC2 does not use a TPS and I don't have one mounted. A TPS is not really necessary in aviation use because we don't have a lot of big rapid throttle changes or throttle-RPM mismatch situations.
This is the TPS adjustment table that I am going to try to start with. Fine adjustment in the middle and larger adjustments at the extremes of travel on the knob. Super easy to change the table based on what I find works best.
Dave, you are a cunning boy! Do you still use one on the throttle, I suspect not? Neil. 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.
