Crazy how long it's been since anything has happened in this thread, in comparison to the BA/BF it seems still that the FG cluster is still a bit of an unknown! I've attached a copy of my bin for anyone who'd like to compare. I'm curious if anyone else here has any more bins I could use to try comparing a few different things as currently only having the two bins (the 99294 and prototype) isn't enough of a sample size for me to figure much out!
What I've currently figured is that any modification to the odometer in 0x6 to 0x25 will result in 'Error' as obviously there is a checksum, but alas the location shared in the first post here (0xD0) is not different in any bin I've seen. (I tried changing the odometer string to the one found in the 99,294 bin; 123,456 tests; prototype bin; and all FF in an attempt to zero).
This theory is solid as if you flash a whole bin as attached sure enough, cluster works perfectly; I got it to work for both the 99k file and the prototype - it would appear the prototype has 580km on it.
The only thing I may have figured out so far may be the HW version at 0x88; but alas I cannot tell if this is right.
My current plan is now to get another cluster and put a socket onto it so I can easily read the chip & test which bits do what; for example when I use IDS to enable police mode, whether overspeed is on, time driven etc. It'd be great to figure out also how the gauge maps work so I could possibly run the cluster in a different car with different fuel senders etc.
