OBC Range indicator

[William]

I've asked this before but nothing that works came of it, does anyone know if there's a cure for the fact that my OBC reads my range at about 250-350 miles all the way until the tank is nearly empty, it never bears ANY resemblance to what is actually left in the tank. Is there a good way of calibrating it?

thanks

you need the code plug for your engine, and
when the tank is empty, sweek the variable resistor on the bottom left.

im sure you have already been told that tho!

I have kind of smithy, trouble is that the little dial in the bottom left doesn't adjust nearly enough. It only goes about 1 litre each way and I need 5+ to get near the correction it needs. Any ideas??
