Eco Gauge Gone Wild

[Threehz]

Everything on my cluster has been working fine except for my economy gauge.

It does not work at all for maybe the first few minutes of driving, and then at some point it will start "working". Sometimes it appears to be working fine, other times it will just sit static at about 40 then jump between 40 and 20 back and forth.

Any ideas? My first thoughts are Si battery?

Unless you have replaced the SI batteries before, assume it is the SI batteries.

Mine does the same thing, It just has a mind of its own. Ill have to try changing those, never knew they controlled it.
