★★★★ Digital Wideband AFR gauge - custom part ★★★★

[george graves]

Thanks. Worked on them about 6 hours today, and have plans for about another 6 tomorrow. Control units are done, working on the display driver board.

Go get some sleep!

Damn George, back at it again with the high quality electronic gizmos!

[george graves]

Display driver board are done. Next: Display boards and then mounting them in the case, testing, shipping. Then off to wrap up some one-touch windows.

Thanks for the update

Wrapped up all the electronics tonight, and all the control boxes - whoosh! Tested, inspected, cased up the control unit and hand tested each one to made sure each were calibrated to be spot on.

I have to get more hazard switches in to finish. But we're 95% done. I will start taking orders for a new batch before these go out - and no, that will not effect the current batch.

I'll be sending out emails soon to verify your address, and to people that don't follow this thread, but ordered a unit, so sorry for the duplicate message if you're reading this.

Sorry for the delay on this, I'm really behind! Eeek!

Great. Looking forward to getting mine.

Up for next batch

[E30-Ellerman]

I'm in for next batch! Any idea when I could expect it?

[Streichholzschächtelchen]

Ready to throw you cash... lmk if you need hazard switches I have a couple just chillin.

[george graves]

I do - I need about 6 ASAP.

[ApexGoblin]

In for the next batch as well. Going to check for hazard switches when I get home. I think I have a couple in the random parts box!

From my build thread:
Wired up the wideband display i bought from george graves. All went smoothly and easily enough. I used the radio switched 12v, ground and illumination wires and the ground and 5v from the innovate lc-2 controller.

All works well however there is about a 0.1 to 0.2 AFR difference between the innovate gauge and this one; nothing major.

Nice!

I can't speak to the accuracy of Innovate gauges, and I don't have any on hand. I can say that 0.1 AFR difference at 14.7 AFR is less then 1% error - so I think it's fair to say, it's a match. (0.1 AFR/14.7 AFR) *100% = 0.68%

What I can tell you is that I don't bother with 1% when I calibrate and test each of the units I build - I do one better, I get down to a few millivolts for it's accuracy across the entire AFR. And that keep it well under 1% error across any measurement. I'm a bit of a nerd like that.

Bumping this... Any idea when the next batch will be ready or when we should send you money? Needing it by end of March or early April. I'll PM you.
