Just wondering how much can you use a GM Tech 2 on a Camaro 1997? Is it for example possible to change miles to km and set clock to use 24 h instead of AM/PM? As far I found out there is very few settings you can change in a Camaro 1997. I tried to find any video for the Camaro on youtube but didn't find any.

 

Since models built for sale in Canada used metric units, change to kilometers should be possible. Might be as simple as changing the instrument cluster. Clock isn’t connected to the PCM or the body control module, so that is an open question. Might want to check the Owner's Manual, since the clock is part of the entertainment (radio) system.
