What we are looking for is an FT232RL chipset. If you aren't sure, count the pins under the dash.Įssentially, what you have to do is convert the serial data coming out of your obd port to something your computer can read through it's usb port.įTDI is one of the most popular companies making these converters. Note that 94/95 cars should be a 12 pin OBD connector. I had to put pressure on the adapter to make it connect to the computer, and after bricking a PCM as a result, I decided to make my own.įirst, this is the post I referenced. My cable, which I had for many years from Red Devil River, started acting up a few months ago. I am not a electronics expert, and I assume I am not in the minority here. There has been other threads here, on the Impala SS forum, and other corners of the web, but I wanted to pull some of that info together, and share my experience.
