Review on 🚗 Enhance Your Speedometer Accuracy with the Hypertech 730120 Speedometer Calibrator by Daniel Aboubakar

I installed this calibrator on a 2015 F-350 6.7L Power-Stroke. It works perfectly, but the quality of the materials was a bit lacking. The white candles to be connected to the car were 3D printed and made from a very fragile material. When I plugged it into the back of the instrument cluster, it was very tight and had intermittent problems with loss of communication (gauges flickered on and off) during a test drive. When the hinge was removed to fix the problem, the cheap plastic began to crack under minimal pressure. looks like it's a one time thing if it doesn't work the first time. After numerous attempts to make reliable contact, I decided to ditch cheap connectors altogether. I actually traced the appropriate wires and hooked up the calibration module to the factory wiring harness. This approach requires cutting and soldering your car's wiring and should be performed by someone experienced with this type of thing. After a direct connection, the module works correctly and has been without problems for several weeks. For the amount paid for this device, better quality connectors should be provided.
