Christen fuel flow gauge

[Yankandbank]

I've a got digital Christen fuel flow and gallons used gauge that no one seems to anything about (locally) other than operating it in a S2B. It has been working great but I think it's starting to go bad. It's about a 1/2 gallon off from the stock fuel flow gauge (it wasn't before or that one is going bad) in cruise. When I power up the Pitts, the gauge would say what I burned, now it shows a random number that starts with a 9. I thought maybe it was a fault code of some sort, but I'm not finding anything anywhere. I've checked all the connectors and everything seems to tight and fine.

Any suggestions or am I just observantly paranoid?

Thanks
