Hello Gaspar

Thank you for designing the fadec, Great unit and its very compact. I wanted to ask a question about the ECO ecu. I have 2 units that came with my JDE-54's

1. Im currently having problems with my bypass setup introducing bubbles. To combat this I thought if I could control the voltage out of the battery I could have a electronic bypass of sorts. I have made a variable voltage regulator that will be adjustable so that I can tune in a 95% pump duty cycle. Is this ok, and what do you think about this approach.

I have found a low dropout voltage regulator lm1084 adj from National Semiconductor that has a drop out voltage of around 1.5 v to use for this purpose.

In my tests so far, as long as the battery voltage is at least 1.5 V above the set output voltage, the output voltage is rock solid when input votage is changed. The turbines were run once with a fixed 5 V regulator but that was too much and the pumps were running at 60% at full throttle, that is why im going to the adjustable voltage. The run was uneventfull, however I did notice that the high end pump % was much more steady than it had been in the past.
