How Does my Car Computer Work?

When you own a computer you often receive reminders to update software and components of the operating system. Much like the computer sitting on your desk, the computer in your car should be scanned to assure that it is working at optimum capacity.


The computer in your car is called an ECU or engine control unit. An ECU upgrade can improve mileage and the overall performance of your vehicle. Solo PCMS is your portal for all engine control units, but before that, you might be wondering what it is and why it’s so important. If you have a modern vehicle, chances are you already have one of these installed somewhere.

What Does a Car’s Computer Control?

“Everything” isn’t much of an exaggeration. ECUs control things like:

  • How much fuel is pumped into the engine at any given time
  • How well the torque and horsepower are distributed
  • Alternate vehicle modes (low emissions mode, valet mode, anti-theft mode, etc.)
  • Emission of carbon dioxide
  • Valve Timing

Essentially, if there’s a part of the vehicle that needs to be controlled, chances are the ECU is the part doing it.

Why Upgrade Your Cars Computer?

Like all computers, ECUs are constantly improving – new models are faster, more efficient, and better able to maximize the performance of your vehicle while reducing the amount of fuel you use. You may not even need to replace the ECU’s themselves- in some cases, the only upgrade needed is in the software.

Even a relatively small upgrade in the ECU can offer significant benefits from your vehicle – from better performance to higher mileage, just about everything you actually do with your vehicle can be done better.

Many vehicles improve so much that the better mileage actually ends up paying off the cost of the ECU – compare that to what any mechanic’s shop would charge for a tune-up and you’ll start to see just how valuable an ECU upgrade can be.

How Can You Get An ECU Upgrade?

ECM upgrades are available from Solo Auto Electronics, the nation’s largest manufacturer of auto computers. As a customer, you’ll also be provided instructions on installing your new unit, a list of frequently-asked questions, and tech support that can guide you through the process if you encounter any issues.

Most installations are simple plug-and-play setups, though a few upgrades (mainly on Honda and Ford vehicles) require additional service. Solo Auto Electronics offers full instructions, detailing everything you need to know in order to successfully install an improved auto computer.

Solo PCMS is a national provider and repair center for PCM, ECM, ECU, TCM, and TCU auto computers.
