Hi,
I bought this gauge from a member of xoc.
I can't seem to get a correct reading from it.
when I start it, it goes about middle and as soon as I warm up.. goes all the way to lean.
and If I go WOT, it jumps to the last led on rich..
what did I do wrong ?

I connected the ground on the block as requested by the instructions.. the other one is a fused live wire 12+.

help.

thanks

Liv
