I have just started tuning my k-pro, using the latest k-manager.
I get corrupted files everytime I take multiple datalogs without saving them. (like "F9" -> drive -> "F9" -> tune -> upload -> "F9" -> drive -> etc.). Everythings fine until I try to open the newly tuned calibration again. It will open, but both the ignition, fuel and cam tables are way off..
So to use my new map after I have shut down k-manager I have to download it from the ECU (not good, right?).
I found that when only doing one datalog run -> upload -> save -> shut down -> reopen. everythings fine.
So I guess that something goes wrong with the map when making many datalog runs in a row without saving the datalogs (we are talking about 15-30 WOT runs).
I have a PRB ecu, intake, header, exhaust..
