I didn't expect to be selling units already.
Realistically, 2 - 4 weeks before I could get something out.
I would need a few days to firm up the pricing, but here are my best guestimates.
Option #1 - fully assembled kit - you will still need to install it and it will require wiring into the electrical system much like installing a car stereo (I am currently evaluating the most feasible way so that as few electrical splices as possible will be required. Price - no more than $400.
Option #2 - unassembled kit - all components required for functioning - however, the circuit board will need to be assembled (you will be provided with all of the circuit board materials). you will need to provide an enclosure and mounting for the controller as well as various and sundry wiring. Price - no more than $250.
The thing about option 2 is that if you assemble it, you will also need a way to test the function of the module, I can test modules that I make myself, but I can only test the function of the microcontroller in the unassembled kit.
Installation time will depend upon your level of skill and familiarity with your vehicle. I could easily do it in less than an hour, but an extreme novice could take 4 or more hours.
Installation will involve:
1. Removing glove compartment liner, lower trim panel on passenger side, and a/c control panel.
2. Making the necessary electrical connections ~15
3. Rerouting vacuum lines (ideally you will test the function of the vacuum system here, which could run into a major time consumer as problems can be a real pain to run down) (vac lines are necessary as the flaps use vac to operate).
4. Mount module.
5. Place temp sensors.
6. Remove servo and replace with heater valve.
The most time consuming step is #2. This takes me about 20 minutes as I solder and heat shrink all of my my electrical connections. If one was to use splice style connectors, this step may be shortened.
I will firm things up soon.
