I just can not figger out WTF.....I would think a speedo would be very linear device in it's response.....why NOT?? according to Garmin NUVI 200w that thing was WAY the hell off
dead nutz on at 10-20-30-40-up to 70, at 90 is only really 87-88, at 100 indicated it's only really 94.....
now here is the weird part....I KNOW my tach is accurate with being 300 rpm high at 3000 and 4500 rpm.....
BUT according to tables off the net, with my o/drive/rear gear set/tire size (275/50/17) and so forth, it WAS supposed to be some 12-15% faster than it really is according to Garmin....
so WTF is going ON?? so my supposed 150 mph run that the tach supposedly confirmed was only maybe 130 if that.....
why would a stock speedo go to over reading like crazy??? is this NORMAL??
both of them, enough to make me go digital, with nice big RED LED readout....If I have to make them myself.....this is bullshit....
the speedo gear I had in there had some 10% fewer teeth than the one in there now...so now it's accurate at slower speeds, but not up topside....
:huh:
