    any interest in a fuel mixture display ??

    Check it out, we're thinking about building these again but not unless we know we've got enough interest to validate shelling out a lot of $$$ to get new PC boards made:

    98 Formula
    06 duramax

    How accurate are those and how do they wire to the O2's?

    Can't really call anything with just 10 LEDs as accurate but with the sensitivity properly set (we send them out calibrated) the two center LEDs represent about 0.45V and 0.55V - and 0.5V is considered ideal mixturewise.

    Simple hookup, just run wires to the sensors or to the PCM and connect them using those blue 3M Scotch-lock crimp splices, that way you don't have to cut any wires. THe unit only needs a +12V supply, ground and a connection to the + lead coming from the O2 sensor.

    They really work well, having the different colors makes it easy to monitor your mixture out of the corner of you eye while still concentrating on the road. They look pretty darn cool too. :-)

    BTW: I'm going to be out of the office quite a bit today but I'll check in on this thread and the one on the new Fuel Injector Tester as I can.

    That could be done but if we decide to make up a batch they're either going to be one way or the other. I thought the linear display was easier to mount, especially if you've got dual O2 sensors because you can stack the flat boards on top of each other or side by side.

    Due to the size of the IC if you were to make a circle it might be squeezable to around a 1.5" diameter but the board itself would be closer to 2" diameter.

    We're thinking with a professionally etched PC board they'll come in around $45 - $50
