This is the first time I have seen this issue and was wondering if anyone else has seen it. or at least to warn others at the very least.
Situation: Car has been sitting in the garage for over a year, has been jump started a couple of times to get it warmed up then shut back off again for months. Eventually when the car was restarted and driven it wont go above 4000 RPM whenever it is above 50% throttle. When the Smanger is open to the file and datalogging, everything seems normal until you give it throttle and the problems start, the fuel maps on the screen will go apeshit and show several values. As soon as you let off the throttle it goes back to normal. Im not sure what actually caused the problem, but all I did to fix it was update the firmware and upload a new file with all the same values as the old file and all the problems went away. I tried to get a screen shot of the problem but i wasnt fast enough. Sorry.

If you would like a copy of this calibration and maybe a datalog if I can duplicate it again, I could probably arrange that. Just a heads up though for cars that may be having problems after a long storage.

The version of SManager in the laptop and ECU don't match. The solution is to re-upload the calibration to the ECU.

Thats what I had orginally thought but nothing had changed with the car over this period of time. It did not have an update or have a laptop even plugged into in months. I just plugged in to find an issue and this is what I saw. Either way, with a new calibration file all is fine.
