Change Your Cars Performance Settings Yourself

October 17th, 2016

I do a lot of work on my own cars. It has been getting harder and harder to do that since the early 1980s. We have had emission standards develop since then, and pretty much everything is controlled by software and servos. One of our cars even has the technology to parallel park itself. I am not a mechanic by profession, but I have been working on cars since I was a kid. I bought an OBD II scanner to be able to check all of the on-board diagnostics and control the electronic control units in the cars. I especially like to use it on my modern muscle car to tweak performance.

Before, you had to go out and buy the chipsets you wanted to increase performance. You can still get those chips for some cars, but for most of the newer ones you just need to adjust the settings using software. However, you do need a scanner that can read and control all of the functions. You do not want to get some cheap aftermarket scanner clone. You want the real thing in order to be able to make the most use of your diagnostic and control software.

Yes, you should know what you are doing. This is very important if your car is still under warranty. My car has been out of warranty now for about a year. However, I have been using the software to track performance and make adjustments for a long time. I set everything for maximum muscle car performance. I do not drive this car for its gas mileage. I drive it on a local track showing just what a stock car can do. These new engines and transmissions are capable of so much more than what the manufacturer software settings allow you to do. If you get an OBD II scanner, you can change things for yourself.
