Hooked the fan up to the car today and ran it for about 30 minutes before it got too cold and had to retreat. Even the car was having trouble keeping the voltage up when it was running

The mercedes fan seemed to run just fine with a 90% pwm at 100Hz. It's not a 'true' test either, since the radiator it was strapped to was empty, and not dumping heat on the controller.

So, at this point, I'll finish up the code and do some more testing, then ship it off to Andrew for more in car testing.

One question though: with the 5 minute ignore button, what do you want to happen if the AC comes on 3 minutes later? 8 minutes later? I assume we'd turn the fan on in both cases, and let the AC override the other command?

If you ever find yourself in a fair fight, your tactics suck.
