when tweaking setups have a way to change back or undo the last 3 changes.

I think not... so if you wangt to change a setup,always make a backup of it, just in case you messed something up.

I tend to select the setup I want to change then press new setup. This will make a copy of your setup so you can roll back if required.

there is an undo button at bottom of setup list

Yeah, as long as you don't klick on another setup or test the one you just edited... So, the undo is a bit pointless now...

I don't know where I put it, perhaps it is at home, but I made a setup sheet in Excel. I print it and write all the settings down and the setup name with what track it is for. I write all the changes down, that way I remember what I changed when I go out to test it. I did this because I made a change to my FZ50 at South City Long and messed it all up. Then I couldn't remember what I changed because I was making alot of changes. It also saves how many setups you have because you can make small adjustments for different track configs and always just go back to the old setting when you change configs.

The undo feature would be very good, if it remembered your previous setup from changing it after being on track. Then you can change it, try it on track, and if you dont like it then go back into the pit and undo the settings.

At the moment the undo feature it quite pointless, as you cant test your setup and if something goes wrong you cant reset it.
