my synce guage is off and i'm wondering if there is an adjustment on the back or something I can tweek. The tachs are accurate and the throttles are matched, just the sync guage is off at cruising speed. Or is this one of those don't bother with it kind of things?

There is a sync module behind your guages. There is a small scew in one of little holes for adjusting the sycn guage.....It looks like an oversized hockey puck....
 
Sweet, thanks. :thumbsup:

It shoiuld WORK?????

I have a sync gauge on my 1990 310 EC and it doesnt work at al...No clue why.....is this abig deal to fix in the worst case scenario??? :huh:
 
Do the tachs work? They are fed from the sync module. Next thing to check would be the integrity of the wires from the sync module to the synch guage. If those look good, that would leave either the module or the guage. I'm not sure how exactly you would check the module or the guage for operation... :huh: ...... Maybe someone else here would be able to help?
 
Yep
