Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

    flashing in another year bin into 04 monte

    I noticed there is no way to disable cat diagnostics on the 04 monte carlo. I found the 03 doesn't have it either, is it possible to flash an 02 monte bin into an 04 monte? My only other option for this car is to run it in open loop but the 04's give goofy command a/f numbers

    HVAC modes not working, help me decifer these codes please.

    My HVAC isn't responding to my commands when I hit the mode button to cycle through defrost, floor, vent, etc. It just blows mostly out of the defrost and barely out of the vent and flow no matter what mode it's in. All the other functions are working. I'm convinced it's one of those...
