The JAW is cheap and has two programmable outputs.
Mine has been working great, its hard to beat if you're on a budget and can assemble it yourself
First, if you can get that bastard to ship it, you've overcome one major hurdle. Next, if you don't have firmware issues, you've covered the next big one. Third, if you install a cold-point compensator chip between the thermocouple and input, you've almost got a decent wideband w/inputs.
IMO Techedge DIY FTW. I've got 2 running, and everything was slicker than dog shit. 6 inputs (6: 0-5v, or 3: 0-5v and 3: thermocouple), programable wideband & narrowband outputs, and a serial output stream akin to Innovate's. Oddly enough it was the only wideband programmed for my friend's Nissan Datascan crap he forced me to use.
For ectune in specific, the LC-1 is great. I sub that in for my techedge when I go mess with my car. It just sucks w/o a sensor cable extension. I made mine with my old PLX extension + connector from a dead wideband sensor.
It's just like the military's version complete with yelling and slurs on your sexual orientation, only you don't have to call me sir or kiss my ass.
I hope you don't shower nekkid together.
