Thank You Mr. Penner

Loss from rear wheel to crankshaft is much smaller than expected.
And it can be measured with a dyno.
At the end of the run you pull the clutch. Now the reel is decelerated by the friction from the rear wheel the drive shaft and the transmission up to the clutch. . This loss is measured by the dyno software the same way it was when positively accelerated to get rwhp.
It is about 12 hp with a Rocket3.

Wow that's a lot less loss than I expected, thanks for enlightening us.

Guys I know how to use TuneECU to do maintinance, adjust tunes and download the tunes while using a battery charger and pulling a fuse to maintain voltage. What I dont know how to do is delete tunes either in the download file or in my saved tunes files. I have several tunes I don't need anymore and would like to delete them.

If you don't want to use a tune anymore and can't figure out how to delete it, nothing stops you from renaming it to "Do Not Use" in your saved tunes file.

Generic instructions for deleting tune files are as follows:

Android (most common TuneECU platform)​

1. Open your phone’s (device) File Manager.
2. Go to the folder where TuneECU stores maps:
   • Usually /Documents/TuneECU/ or /Download/
3. Long‑press the map file (.hex, .bin, .map) you want to remove.
4. Tap Delete.

This removes the file.
