Works Great!

This product works great to correct for different gear ratios or different tire sizes. It takes a couple hours to install, but it is definitely worth it, and it is easily adjustable.

    Speed Cal

    The product works great. I tested it with my GPS after the install it was right on the speed that it should have been. Just a couple of install tips. 1. When you do the code and input the #'s of either zero or one for the codes. Zero is the switch in the down position, and 1 is the switch in the up position. 2. If you have a car with a traction control button and a 12 volt outlet, you need to mount the speed cal long ways right in between those two connectors so your boot cover will snap back in place correctly. The install instructions show the black speed cal unit off to the driver's side a little bit, it needs to be right in the middle. 3. Before you disconnect the battery check the power outlet wires on the 12 volt outlet to see which is the constant power one with a wire tester, a multimeter is not needed, figure this out first then disconnect the battery. It is well worth the $ and works great.

    Perfectly accurate

    My 96 went from 3.27 to 4.10 gears. They swapped out the speedo gear, but my speed was still off by 5 mph at 40, and about 10 mph off at 70. I was scared to drive past cops, and I was getting passed by people when I thought I was speeding. Yanked out the speedo gear, put in the stock one, and installed this Speedcal. Such a shame its been discontinued. Simple install and speedo is dead accurate now (gps verified) Love it.

    I have a 96 GT convertible 5-speed with the 2.73 gear that I converted for a 2000 4.6L SOHC with a 2003 6-speed transmission and a IRS Cobra 3.55 gear axel, with that I added new wheels 315/35/17 so you can imagine my speedometer being bizare, I used the SpeedCal with the proper numbers and voila, all is working good. Even if I change tires or gears later, I can still work it out. It is worth the investment and works very well.

    speedcal

    fast shipping as usual. simple install with instruction on website. we did have the wires backwards in the connector because they were a different color than in the instructions. no big deal, just put it back on the lift and switched them. works great now. i didnt put the red wire to the 12v outlet as instructed because it always has power, instead i used a key on powered only wire on an unused pigtail nearby.

    Sweet and Quick to Install

    Took 20 mins to install using a lift, directions are easy and setting dipswitches is a no brainer. Very nicely made and conceals nicely...makes life much easier and saves a lot of money(No TUNER NEEDED) I would highly recommend.
