Product Description
Are you running a vehicle with a GM GEN4 LS swap and not using a GM TCM or factory GM transmission? If so then you probably know that the vehicle speed will read 158MPH all the time. This can cause issues with the speed limiter among other things.
This EZ Module will wire into your CAN DATA wires and simulate a GM TCM-Transmission and supply the ECU with a 0 MPH reading.
