Progman software is the name given to the software in the ECU. Sometimes, some of the niggles are caused by bugs in the car's software and "re-flashing" the software with the most up to date version is done in the hope of fixing it (with your re-map, Carlos, flashing the software is a dirty word
)
There seems to be a lot of versions of the software about and the Progman version referred to in the OP post is alleged to dis-improve the car.
