Did you know that electrical systems in automobile technology go back as far as 1834? Obviously, modern cars operate much differently. Today, your vehicle has as many as 12 specialized computers supported by a main computer. You’ll find more than 5 miles of wiring and as many as 45 sensors. Today computers control about 85% of vehicle functions including engine ignition, fuel delivery, emission devices, transmissions, heating and air conditioning, traction control, 4-wheel drive, seat position, mirrors, anti-lock brakes, alarms, GPS systems, speedometers, gauges, air bags, and even your alternator.

These computer systems advance with every new model. That’s why Tunex technicians regularly attend manufacturer training as well as Tunex corporate training at our own education center. Your car’s complex computer controls need to be serviced by experts in today’s advanced vehicle technology—the car care experts at Tunex.
