Default My In-Progress JAW (wideband controller) build and review

So I got the JAW + Display kit a couple days ago and built it last night in about an hour. This is how it comes:



Everything came in 1 antistatic bag, so I hope you're good at reading resistors, or at least have a multimeter available.

This is everything out of the bag:



Not too many components, nothing complicated, nothing real small to solder.

An hour later here is all of it built:



Note that I didn't mount the display to the board because I want to put it in a little project box from radioshack and mount it on top of the steering column cover.

Here are closeups of the controller board and the display board:




I used a 12V 1.7A AC adapter that I use for my MegaSquirt Stim to power the board, plugged the serial cable in, and fired up the software. The software is really easy to use and very basic, just select the COM port and go. The firmware was uploaded in less than a minute and voila, it all works.



Overall it was very easy to build. If you can build a Megasquirt this will be duck soup; however, there's no real way to test it until you're done. At only 80$ not including the sensor, this is a great deal. Now I just have to wait for my wideband o2 sensor to come in and figure out how to configure the JAW output for the MS.

just set the MS wideband input to one of the lc1 settings and then set the output range of the JAW to the same range. No reason that should not work in my mind. Thanks for taking the dive and I will keep monitoring your progress. It should work fine though.

man I might build one for the GTO and have a bung welded at the collector.
I can put the board under the dash and the display in the space for the ashtray.

I wonder if the WB mounted after the collector is too far back or if I should mount it on one header.

You can hold a butane lighter under the sensor....dont light the lighter, just let the butane out...should trigger the output on the sensor.

Group buy on the local board is on-going. We should have 8 or 10 of them eventually up and running....

Dave,

I don't have an LSU wbo2 sensor yet, so nothing else has been done. Plus I'm moving to Huntington Beach in 5 days and I'm looking for apartments. I most likely won't be making a case or anything for it until I get moved in next week.
