MPG swingometer thing...

[Stealth]

OK,

mine only seems to kick in when it gets to 2500 revs, and then seems to be really sensitive..

I think I have the wrong white plug in the dash..!! would this be the cause..

If so does anyone have a 1 377 670..??

do you know what plugs are for what model? - i've got a thread going with a list of them in a few below this one, but I don't know which to put in my 87 320i (there is two possibles)
