I scoured the internet for days, looking for some sort of compatible digital dash. The AIM was all I could find that truly guaranteed compatibility for the Cobalt. I know there are some particulars with non-generic CAN PID/data protocols (especially GM) when using a factory ECM that are very proprietary/model specific, thus a specific list of model/year compatibility included with the AIM (you can find that list on their website).
What generic or proprietary data does the Cobalt use between the 5 different ECM’s? What is actually on the list of “generic” data? I know theres an actual list somewhere. Is the generic data adequate enough to warrant the price of the dash? Perhaps you will get water temp, MAF, KR & fuel level, but no boost or IAT2 data. When they say “compatible with”, I would call the company and ask them specifically what data is included. So far, Aeroforce seems to have most of the data figured out and with zero CAN bus interference. Too bad they don’t have a dash panel.
I spoke to a few of the AIM techs and there are some small issues with the AIM / GM Cobalt SS CAN bus that they are not even willing to revisit.
The fact that these Cobalts are already over 10 year old cars means there is likely little chance of motivation for aftermarket support anymore.
I also know its a HUGE rabbit hole and massive learning curve to jump into, thus the reason these displays are so expensive.
