Little update on the bmw fuel gauge. I had some play time today so i hooked up a 500r pot and made some measurements. At 500r the wiper of the pot read 3.75v and the gauge read just over full. Reduced the pot to 3v then 2.5v. Gauge stayed the same. Recycled the ignition switch and at 2.5v gauge read just over half full. Reduved to 1v. Still no movement then recycled ignition and gauge reads about 1/8th.
So it looks like i can "fill" the tank as quickly as i like but it won't "empty" very fast. So it looks as if the stock gauge is useless for soc as its the opposite for an ev. Fast drain and slow fill. I'll be getting rid of the bmv600hs battery monitor soon now that the lcd module can measure charge and will just fit a normal resistive fuel gauge in the pod.

Now, Cole, when you shift the gear and that little needle on the ammeter goes into the red and reads 2000 Amps, that's bad.
