******-a, Bubba!




So, the 9926 circuit just didn't cut it for you, then?

Man, I'd really love to get in there with an actual oscilloscope on one and figure out what was going wrong. So far, I've just been deliriously happy with that chip.

I dont know exactly what is the issue with the 9926. I haven't given up on it yet but I dont have an o-scope.

But for now it works so....

Maybe the Y8s should send his little 9926 board over to the Ben?

That extra load on the alternator is going to kill your economy man.

We should have one of Jean's 9926 boards around here. We've also got a new sequencer to test out. The hardest part will probably be the fabrication of a live sensor test rig.

I used kday's 9926 reference circuit. super low component count.

Matt, did you connect the VSS to the MS3? If so, what settings did you use?

Yes, I ran VSS in to the xpander CAM input without any extra circuitry. I first tried PT4 but there was no pullup. It'd probably work on any of the inputs with a pullup.

(for reference for the cam input)

edit: oh you said "settings"...

Matt,

Did you get the max9926 based input circuit working on the car?

he never did, he went with Abe's circuit.

Honestly, you dont even have to build that... should work on regular Opto input and the MS3x cam in.

Nope, never did get the 9926 input working.

If anyone wants the circuit to try, I can mail it to you for a buck or two to cover postage.

I recommend using the VR input with a pullup. Works fine and is easy.

Put a MAX9926 on a Toyota last week, worked fine. Haven't tried one on a Miata yet.

Hell yeah. I would love to play around with it. What is your paypal id?

Thanks.

Thanks for the info guys. I have Abe's circuit running as part of his pnp board. I was just looking at options for getting rid of that board.

when I say "someone" I mean someone with at least an EE degree and an oscilloscope that can figure out why it doesn't work consistently with the NB sensors.

is that you?

Well, background is chemical engineering/Physical chemistry and I have done a lot of instrument computer interfacing. I can give it a shot and see if I can figure it out.
