ECU - The Vehicle's Computer

Today, vehicle manufacturers include at least one computer or electronic control unit (ECU) in vehicles. This computer's main function is to monitor and adjust engine and transmission operations. The computer receives input information from different sensors throught the vehicle. The computer controls spark plugs, idle speed, and fuel injectors so as to get the optimial performance from the vehicle's mechanics. Failure of the ECU will greatly affect the things it controls.

To get the most out of the vehicle's ECU, have it evaluated regularly for updates and proper operation. If it is already failing, make sure to have it repaired or replaced. We are the expert that can handle your vehicle's computer in Waldorf, MD, call us today (301) 645-3722.

Computer Reflashing

Boswell's Auto Service has state-of-the-art equipment to provide computer reflashing to our customers in the Waldorf area. The primary reason to reflash a computer (which basically means updating or reinstalling its software) is that an update has been issued by the manufacturer.

It's a very simple procedure, and there may be minor updates that the car hasn't had. The manufacturer may have tweaked the transmission-shifting algorithm or some other parameters that are not crucial but may bring slight improvements to drivability, mileage or emissions.

Since auto manufacturers are coming out with automobile updates every day, there may be a reprogram available for your vehicle. Stop by Boswell's Auto Service or call us at (301) 645-3722 to schedule an appointment!
