Nisonger should be able to do so.

I agree if Nisonger can't then no one can. You may find it less expensive to buy an inexpensive GPS and use that as your speedo. That is what I do.

I have the gps but it would be nice if it was a bit more accurate. I will try them.

GPS a bit more accurate? Doesn't exist. Please explain why you think a GPS isn't as accurate as a recalibrated speedo. There is nothing more accurate for current speed and distance than a GPS unless you can afford a GPS thatr is real time correctable or on military P-code.
Thanks,
Jim

Sorry. yeah thats what I meant. I want the speedo to be a little closer to the speed. THen it counts the miles a bit better and so on..

You mean, the odometer is supposed to work in these things???


;)



Seriously, mine's originally for the 15" wheels, I've got 7.5x16's on it instead.... but not only is it off, it bounces madly from 0 to 30mph, then stabilizes at about 28 (but I'm really doin' 34 or so by that point....)

Randy, in the event you are an iPhone 3G user:

At $1.99, it's the cheapest most accurate speedometer out there.

There are other apps out there too, like top speed and quarter mile calculators, in case you are curious.

The speedo drive gear ratios are different enough, that you won't be able to get a series speedo any closer than it is now. A Defender speedo is the same OD, if you wanted to swap one in, and other than no idiot lights, it will look almost right. If you want to put some Defender speedo guts in your series speedo, I have a set you can have.

As for using GPS as a speedo, I would have to argue the accuracy question. The slower you are going, and/or the straighter the direction, the more accurate it will be, but the faster you go, and on multicurved roads, the readout is only going to be a point to point average. The speedo function is withing the guts of the GPS unit, not supplied by the satelite. Speedos, however, aren't worth a cr*p at telling you where you are.

I love my Mac. Threw all my PC's in the trash..:thumb-up:

Is it difficult to switch the gears in the speedo? I have had one apart to look inside but that was about it..

I'm not suggesting disecting the mechanism, just changing the whole guts out.
I don't hate Macs, I just know I can buy 4 PCs for one Mac that Apple will update the week after I bought one. French may be a nice language, but only the French refuse to speak English.
