Why is it I can't scroll between d1 and co on my gauge?

Did you try and disconnect the battery or pull the ecu fuse? Maybe something just hung up

Ya, tried both.

Do the buttons work in the normal mode?
Did you try to call Ulmers or someone who does tuning, to see if they ever came across it?

everything else seems to work fine

You have to ground out the one wire off the plug on the left side of the upper frame. Can't remember what which wire. But you use a paper clip
