I have a friend with a 99 EX who needs to have his speedo set 7 MPH slower than his actual speed. I have never messed with speedo calibration, and I haven't ever seen anything about it on forums, just wondering if this is something we could change ourselves, or something he has to go to a shop for.

I guess we could play with resistors, anyone know a convenient place to access the speedo feed?

Anyone know a shop in VA that would do this for him?

$100 for that? Poo. I have larger wheels and tires (than stock 13") B16 LSD and a KPH cluster. Just convert and memorize the conversion, it will make you smarter too.

 

for 100 bucks you might aswell find a used cluster with the same amount of miles

 

My question was, how do I set his speedo to read 7 mph slower than his car is actually traveling? (if his actual speed is 67, his speedo reads 60). Like people do to get out of a ticket... set the speedo slow, then get it officially tested. If this turns into another reckless for him, he loses his license. The yellow box looks cool, but only as a last resort, since he needs to have it tested soon, and since the thing is so expensive.

 

I checked out the yellow box, and my friend is going to buy it. My only question is which wire do I need to splice into. (please don't tell me the speed sensor wire, I know that, how do I know which one it is?)

 

red = hot wire
black = ground wire
other = signal wire

There are only three on that speed sensor...

 

why does his speedo read so high? 19" rims? what was he using to determine he "real" speed? after i went from 175/70-13 to 205/45-16, my speedo became more accurate, as the stock speed reads optimistically. i used one of those "your speed is XX" signs on the side of the road for surveying. with taller tires, your speedo will read slower than before

 

ok, back to my first question, does anyone know a shop in VA he could go to to have his speedo set back 7 mph for cheap?

taller tires! i don't think you can change the speedo without adjusting the needle.
