I decided I am going to buy this and test it against my lc1. If it works out it is going to be installed inside my next MS and the lc1 will be gone.

I figure, I already have the sensor and its only $40. SO I don't have too much to lose, and it might help someone here if it works well.

Installing it in the MS case itself would be awesome.
I want to get one to make a transportable LM-1 style Wideband. One that works off power from the cigarette lighter and some cheapo LCD panel meter gauge. Hell it would cost me a whole $100 with the radioshack case.

that would be pretty simple to rig up I would think. I cant order it like right now, but within a week or so I will. I am trying to have a new motor in within the next 2 weeks so I will do it the week after that happens.

Use that panel meter. It would be perfect.

its not THAT easy lol. You need something to control the output to that display. That would be a whole other circuit. You would be better suited to buy a digital readout af guage and just take it apart.

Why is it not that easy?
To see a video of JAW working in My 1997 Jeep TJ click here. The output is being read by my voltmeter, I have programmed one of the outputs so that the output voltage is AFR/10, 1.47[volts]=14.7[AFR].

For the panel meter. Can you not just program one of the outputs similarly to what he has or:
From Innovate Motorsports Forum for panel meter:
Set 0.8V = 8AFR, 2V = 20AFR. Then use the jumper settings on the $9 panel meter to move the decimal point one position to the right. If you want the results in lambda, program 0.5V = 0.5 Lambda, 1.5V = 1.5 Lambda and leave the decimal point alone.

All of that is copy and pasted from other websites.

well the voltmeter has the circuitry to output numbers based on voltage readings. You could rig a volt meter to do that easily enough, but they dont run on 12v. But you could use resistors to solve that problem. The lcd display you posted is just that, an lcd display. It isnt programmed to do anything, that I see at least. What is posted with it doesn't lead me to believe it would work out of the box.

I didn't think about using a voltmeter though, that would be a cheap method. The crap one at rs is like $12 I think. You could take it apart and use it, albeit it is not that compact because you have all the excess circuitry. You might be able to find a cheap, small voltmeter on ebay that only reads voltages and not resistances, etc...

That lcd might work I guess, it does list at all what it does. Without specs or a datasheet I really couldnt say with any certainty.

I saw a cool post a while back of a guy building a bench top power supply for his electronic projects. So instead of having a 12v battery around he could just have a power supply to plug into.

Anyway what makes this relevant to what you are talking about it that he bought a $3.99 voltmeter from one of the major cheap tool stores. He took it apart and traced out where the leads were on the **** that controls the function. He soldered a wire on to always read voltage. He then cut off the bottom half of the circuit board he wasn't using. Then hooked it up permanently to the power supply so he would always have a readout for voltage.

Shouldn't be that hard and $4 isn't bad at all.

I found the link to the voltmeter hack if anyone is interested how it was done.

Towards the bottom of the page.

Bringing this back, anyone try one of these yet.

Going to get one through a group buy with the local miata club, want to run it with my megasquirt, any reviews or will I be the first?
