@Norm Charbonneau posted:Guys, before we get too far keep in mind my example did not have EOB and was a purely mechanical issue. I popped in to the thread since I was tagged and thought I could add a bit of insight.
In any case some versions of EOB equipped engines had an audible switching frequency when run in a closed loop mode. TAS cured it with new code that could be obtained on request many years ago.
Thank you for the information regarding the new code! I did not even consider something like that. I have done reprogramming and code changes with MTH engines but never on something like this. If it is not to complicated I am more than willing to give it a try. I guess the only question is if the new code can still be obtained? Sounds like I’ve got some more research to do. BTW Norm big fan of your work!
