Or you could wait for my senior design project to finish ;) Its a replacement similar to the Unwired tools, but should be about half the price ($350).
If you can DIY for only as little as half the commercial price then the commercial price is probably pretty reasonable! You could probably do very well with a PIC (or some such) and a monovalve and vacuum valve array out of a later car. And a tiny amount of software of course! For the cars that accepted both the Chrysler and VDO ACC systems (107 & 123 but what else?) I'd be sorely tempted to try to convert to the other factory system. Not that this would be the project of an afternoon or two! Lessee, a nice non-rusty 6.9 with either manual HVAC or a VDO retrofit? Yeah, I'll add that to my fantasy pile o' cars. -- Jim
