About Known Good
What is this website for?
The aim of this website is to be able to come in and grab the waveform that you need, at no cost to you. Our only request is that you turn adblocker off so we can make some money for the work it takes to upkeep, manage, and organize the waveforms. Soon, authorized diagnosticians will be allowed to add their own sample waveforms for others. At Known Good we believe in the right to repair and only want to push the automotive industry into the highest ranking of blue collar work.
