ESU Aototune

Hi , I recently purchased an ESU Loco decoder that has the "Autotune" feature and have tried unsuccessfully to carry out the procedure on a programming track using a sprog and decoder pro , I have set CV 54 to a value of zero and configured a JMRI throttle to show F1 on the first throttle button, but on pressing F1 to start the tuning procedure nothing happens ie the Loco does not move , if I try to run the Loco using the throttle in the usual way everything is fine but I can't work out how to get the "autotune" to work , can anyone advise please where I may be going wrong ?.

1 - have you turned on track power to the loco with the Sprog after setting the CV ?
2 - when I usually do this, I'd do it on the layout, as the performance measured will be different depending on the track voltage from the command station.

Yes, it does "just work". Program the CV, call up the loco, set direction to forwards, press F1. (Catch loco as it shoots down track at 100mph).
You may have to adjust the motor CVs further after the auto-tune is complete. Its not a perfect method to adjust things, but usually gets something reasonable.
