hi Gillis,

I had the same questions going round in my head. Sorry I don't have the answers!.

The type of memory varies between ECU's, on the early single spark F650GS BMSC the program code was in an EEPROM external to the processor, on most of the more modern ECU's the memory is internal to the processor. BMW set limits on how many times an ECU can be reprogrammed, their artificial limit is very conservative & over time they have increased the no of times an ECU can be programmed, the limit on the later dual spark F650GS is 64 times. With Dash assemblies there are multiple storage locations dependent on the type of data.

Each time an ECU is reprogrammed it stores info about the reprogramming  & the BMW programming system looks up that info to determine whether another programming is permissible. On the latest models reprogramming is almost unlimited

Mike, the dealer statement "The reason given was they didn't want to use up memory, as it may prevent a future important release being able to be loaded." is BS & shows the person who stated that does not understand the ECU's or basic processor programming/operation

sgm:
Thanks Wayne for your clarification!

Any idea how many times my bike's ECU can be reprogrammed? Is it possible with the GS-911 to see how many times it has been reprogrammed (I know that mine has the original program), or number of updates left?

Model : R 1200 GS (K25) 2010
