Many car owners are surprised to find that their cars and trucks are partially controlled by a computer system. Newer models have upwards of seven computers controlling functions such as the airbag control, cruise control, climate control, fuel injection, transmission and more.
The most powerful and commonly replaced computer component is the Engine Control Unit, or ECU. The ECU is designed to ensure the best fuel efficiency and mileage for each car. In any given second, the unit performs millions of calculations on functions concerning the best spark timing, and determining how long the fuel injector is open. These small computers contain a 32-bit, 40-MHz processor and house less than 1MB of memory. Although this may seem small compared to most desktop and laptop computers today, the ECU is designed to be quick and efficient.
As with any electronic device, ECU’s are not immune to failure. However, many times a car’s problems will be misdiagnosed, rather than directed towards the computer itself. Misdiagnosed parts can include the battery, injectors, TPS switch, and many other sensors throughout the car. It is important to examine all contributing factors when addressing the car problem, or it could result in the owner spending over $1000 in guesswork.
Once the problem has been identified, the true challenge begins. Finding the right ECU unit and vendor is an important step to getting a vehicle back in working order. Sources say to stay away from the dealers, who will often overcharge for the part. There are many vendors available online with custom options, a wide range of products, quick turnaround and low prices. Some of the most popular vendors include Auto Computer Exchange, All Computer Resources Inc. and SP-ECU. All of the companies offer custom made parts that are tested to fit your model vehicle as well as a 14-day refund policy. These online resources supply consumers with the parts they need at much lower prices than a dealership.
To ensure a positive transaction, take advantage of the large amount of customer testimonials available on the web. For example, a happy customer reviewed Auto Computer Exchange to say, “These guys are doctors in Automotive Computing! They saved me an absolute bundle and are the most professional, courteous, and fast people in the business. If you are having a problem, don't waste time, call them immediately.”
There are many places online to find the parts needed for auto repair. Finding the right fit and price is the most difficult part. Be sure to utilize the web to research all aspects of the problem, from origins, to manufacturer details, testimonials, and company policies. When the problem is fixed right the first time, it will all be worth it!
