 Product Description For most 2WD and 4WD GM, Ford, Dodge and Toyota vehicles.
Virtually every vehicle manufactured since 1992 is equipped with an electronic speedometer that uses a sensor to read vehicle speed rather than a mechanical cable. This speed signal is a big factor in the overall performance equation. The speed sensor sends its signal to the Engine Control Module (ECM), the Power train Control Module, transmission, and if applicable, the anti-lock system "brain." When tire height and/or axle gearing is altered, these control units receive erroneous information. In all but the most extreme cases (really huge tires), an incorrectly calibrated vehicle will operate, but not at its peak. For example: if a vehicle is factory equipped with 28" tall tires and they are changed to 35s, a 20% change has occurred. Unless remedied, the various control systems will "think" that the vehicle is traveling 20% slower than it actually is. To make matters worse, newer computer-controlled vehicles have become extremely sensitive to changes in tire diameter and axle gear ratio. The reduction in performance can be difficult to gauge, but it is real. Plus, the number and degree of malfunctions increase as speed signal inaccuracy increases. The TruSpeed addresses all speed signal-related problems; it doesn't just correct the speedometer. How? The TruSpeed module installs in-line with the factory electronic speed sensor and converts the wrong speed signal into the correct one for your vehicle's new tire and/or axle gear ratio combination. Because the signal is altered at its source, all speed-sensitive vehicle systems will receive the correct speed data, which restores all proper functions. The TruSpeed is available for most domestic and import vehicles equipped with an electronic speedometer. Superlift TruSpeed Speed Sensor Calibrator Main Features:

Customer Reviews
The hardware works great. The instructions were a little off, but if you have done things like this before, it is pretty easy to install. Calibration can be tedious, especially if you want it very accurate.
Ov- erall, a great product.
This was the perfect part for a perfect lift. In lifting a truck, changing tire ratios and gearing ratios is a job, and having this module helps complete the project and complete it right. There was indeed a performance difference after adding this recalibrator. Shift points became accurate, the converter knows when to lock up, fuel consumption declined considerably (15 MPG now... about 12 MPG before adding the module)....I had lifted this truck prior to adding this recalibrator and the truck was very sluggish....aft- er adding it I was amazed on how the vehicle was so speed dependant and that a
Easy install, good instructions and easy to adjust
The installation was fairly straight forward, except the wire color for connecting to the speed sensor was off for a 2006 Wrangler. The instructions only go up to a 2003, even though the unit works for the 2006. I called Superlift, and they put my on the correct wire (dark blue w/orange stripe) for the 2006. Once hooked up and the unit calibrated my speedometer is within .5 (1/2)mph, closer than most factory speedometers.
Nice to have a Jeep Rubicon with 4.5 inches of lift, running 4.88's and 35's and having a speedometer that is right on the money. The unit works as Superlift says it will
Easy installation, about an hour start to finish. I Callibrated my speedo after installation with a GPS and then double checked with a Speed Radar, and my speedo seems to be dead on.
Great product. Recommend to anybody that uses larger than stock tires. My speedo is calibrated better than new & the tranny shifts perfectly now.
(2000 Tundra)
Great service from 4WS! On the TruSpeed both of the power and negative wires were too short. I had to lengthen both for my 2000 Tacoma. The other two wires that go to the speed sensor on the back of the transfer case only had a few inches to spare! Overall the kit seems pretty good.
Tru speed works great.
One hitch though. The directions do not include how to connect it to RAMs with Rear Wheel ABS . So if you have a RWAL then it needs to be connected between the CAB and the PCM, to the white wire with the orange stripe.
Shipping was very fast and the customer service staff was excellent
Ordered one Superlist TruSpeed Speedometer Calibrator. Order arrived within a few days (Fast!). Packaging was sufficient for protection of the item.
The TruSpeed was harder to install than I thought, and thats because of my truck and the layout of the wires. Once I figured how to get to the hidden wire to splice, completed in no time.
TruSpe- ed works like a charm. Recalibrated my 35" BFG's and now set to GPS. Placed new 37" BFG KO's on, reset the TruSpeed to the second setting, now have two setting's. One for the 37" BFG and the other for the 35" BFG's. BTW, This site had the lowest pr | ||||||||||||||||||||||||||||||
