Mine controls everything I need it to. The stock climate control had the 5 different blower modes but I only ever used face/defrost so I have it just toggle between those. The heater was the toughest part as it's run by bowden cables so I had to build a linear actuator and use the fusion brain to switch the polarity going to the motor in order to push/pull. The one thing lacking that I'd like to eventually be able to do is the ANTILINK function where by activating one of the blower speeds would deactivate any others that were on. I never got it to work correctly and MDX seems a little too complicated for me right now.
