BUYER BEWARE! NOT ALL COMPUTER SELLERS ARE EQUAL.
We are the ONLY company that runs every computer through a computer aided vehicle simulator to test for quality and compatibility with your car & VIN.
OVER 100,000 Customers Served
Every unit is programmed & tested in our facility in Cary NC
CarComputerExchange fully rebuilds and tests ALL computers. We are the ONLY seller that runs each computer through a computer aided vehicle simulator that tests every circuit in the module. Other companies run limited tests.
Most companies run limited tests. Some online stores simply repaint old units and sell without testing. Don't fall for the CHEAPER option.
Our testing & rebuilding process starts with a deep visual evaluation of the circuit board and all the electronic components. From water or acid corrosion, to fire or burn damage, we pay attention to every detail. We also scan the ECU memory or CPU to make sure that it is working properly.
We then test the ECU's with our proprietary electronic lab equipment on our bench, which emulates the car's engine to ensure accuracy in every diagnosis.
