Well guess what? programmed up a 2420 , dropped it in. Works perfectly. Was able to adjust the gauge up and down with the 5k pot etc. Changed to 488hz did help the noise quite a bit. Might add a cap. Assuming that there are no bugs in the 2480 code and given that the 2420 working removes a hardware issue that only leaves the devices themselves. Bad batch? static damage? Gremlins? Anyway main thing is i have a fuel gauge. I still doubt it would work on the bmw gauge due to the software filtering. At best it would be woefully inaccurate.

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.
