Just what I've been looking for! Apparently it's been out for about a month...
They're still getting the bugs worked out of the system; currently the 0-5 variable volt output can only be directly related to a single input, but there are 5 on/off logic outputs that can be controlled by up to three input factors.
As for inputs, it comes with provisions for one thermocouple input, 4 0-5v inputs (which is apparently the standard for pressure senders, mass air flow sensors and RTD) and one square/ frequency input for tach signals (think that'd work with a alternator clamp?).
I think I'm going to have quite a bit of fun with it. $200 for a 32 stage 3-input programmable controller that doubles as a programmer, PWM controller and datalog?
