Default Speedo/odometer calibration


That is my bike, 99 FXSTC 1340 cc Evo single cam. I replaced the speed sensor on my 6 speed revtec. It brought life back to the speedo, but, when I know I am doing 60 mph plus, the needle struggles to go past 30 mph. Also the mileage is counting by half, takes two miles to click off one. I think I have part of a recalibration unit under my dash. It is a square black box with a set of 3 wires going in and out of it, it also has a small red wire going to the ignition switch connection that only has power on when turned on. It wasn't in line with the speed sensor, meaning it has the same connector as the speed sensor and was connected in a circle. I placed the speed sensor in line and it didn't change anything.There is what looks like a coaxil plug on the end of this box, red, like you hook up your TV. I found a picture of the Speed Calibration Unit online and there something plugged onto the COAXIL cable but the pic is cropped and you can't s it all, I have asked for a photo of the entire product.
I am not certain that the speedo was ever correct, but the odometer must have been working okay up tp now, as I only rode it about 1k miles and I had a back operation, can't ride, owe Uncle Sam, anyway the mileage is in tune with what the title says when I bought it last year.

Default Please help me, i found this

Speedometer recalibration unit by speedsupplies. This is what I have, except for the wire plugged on the red coaxil post that is not completely pictured. Can I take my speedo and sensor to the stealership and have them calibrate and/or test my speedo? I wish I could see all of this product pictured below.

Default Problem Solved by Scott Holton and myself

Hats off to Scott Holton of J & P Cycles. He found that the box pictured is indeed the calibration unit that is no longer made, he found some instructions. All, I had to do was follow the instructions and make a way to close the curcuit of the red coaxil plug.
