JAW DIY wideband controller option?
 

http://www.14point7.com/JAW/JAW.htm

Check it out. $40 for a wideband controller. Add wire and a sensor and you have a wideband with the same functionality of an LC1. I don't have one nor do i know anyone that does. Not endorsing the product just thought it might be a new option for people to save the extra $75 that the LC1 would cost over the cost of a bosch sensor, this controller and some wire. That is assuming the bosch sensor is around $50 which i think it is from a few places.

I might check into this. I have an LC-1 on my red Miata and would like to run WB on my blue Miata. Since I only use the WB now and then (once per year?) I was going to just pull my sensor and buy a partial kit from Innovate. This looks like a better (cheaper) solution.

Ohh I can build it myself. I am starting to like these DIY soldering projects. I might be down for it, but it depends on how much school work I can get done in the next few days.

wish it had a cover of some-sorts.

Judging by the size relative to the penny it is small enough to fit in a $2.50 project box from radioshack.

then as long as you can really program the outputs....looks like you'd save close to $80-100

basing that off the LC-1 at $180 shipped.

My only issue with DIY wideband stuff is the fact that if its off... you won't really know. At least you can have some sort of faith in produced systems.

I'm very tempted about this. The guy is local to me here... from the info on the web site. It definately seemed like there was some CDN content. <G>

I'm going to shoot him an e-mail and see what's up with this.....

Dave,

www.wbo2.com hello!

great products and they sell you the enclosure and cable and sensor in some cases.

So am I wrong or is everything on wbo2.com more expensive than just buying an LC1?
This DIY kit with sensor is less than $100, then you could to the $8 LCD display and have a sub $110 WB.

This looks slick, if I didn't already own a LC1 I would definitely buy this.

wow. Looks interesting.

i really should learn how to solder and work on electronics boards. I was taking a class in HS but I never finished because I transfered to the "magnet" school in my district and they were pretty much just academic classes

Why is it that no one else is worried about DIY units being accurate?

Save money
You can check vs. a dyno before tuning

Ah, you assume that the WB on the dyno is accurate too. One of our local dynos here I wouldn't trust any number coming off of it.

But yay for saving some bucks!

You're serious.....it is only interpreting voltages. It doesn't take a cray super computer to do this.

yeah, there was an article in GRM about this this month. i would rather be certain of my AFR, and not have a nagging suspicion that 12:1 is 11 or 13. It's only 50 or 60 bucks more.

I use the Gibson just in case.

Most of us are having fits trying to get a LC1 to work much less a home made WB02 comeon guys we aren't all solder junky's here give us a breack wiring the stuff in was bad enough. :p

Yeah takes me weeks to hook up 12v and gnd.
:) How's the car doing Richy? You get those sweet mounts yet?

if i can install a LC-1 anyone can....i acutally figured it out...

oh wow that is cool, i'm gonna order one

The usps tracking isnt saying shit the harmonic balancer should hit today via UPS though so we shall see. So far new diff axles check, everything else is sealed or in the mail comming to me hopefully :D

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.

Nice, I'm excited now. Makes me want to get one.

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.

like this one at the bottom http://www.prosportgauges.com/Prospo...l%20Gauges.htm

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.

here you go, perfect. http://www.web-tronics.com/led5vcogrpam.html

Think those might be the same products. Cool stuff man, now I really want to build one.

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 knob 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.

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?

looks like youll take the dive first then. I wont be buying it for another couple weeks.

I ordered the DIY kit with the DIY display a couple days ago. It's coming from canada so I should be getting it at the end of this week or next week. I could probably put it together in an hour or so. I'll post up a review of it as soon as I get it.

I might just order one of these myself... I've been wanting the AEM gauge/controller... but this will save me nearly $160. That's considerable enough to be worth the gamble.

I have to get one now :( When I swapped out the blown motor for the one Im using until the FE is done I forgot to remove my wideband. The LC1 ended up sitting up against the exhaust for a solid 30minute test drive. Needless to say, I got to see the inside of the device.

Neo, what was it you melted, the controller box, or the sensor wire? If it's the sensor, just get a new one from bosch -- VW dealer. Or you can get the box, and use the existing sensor.... <G>

I'm going to order one shortly as well.... probably within the next week or so.

Dave,

I melted the complete lambda sensor. It no longer powers up at all.

whoops. Innovative just sent me a new one ...but it failed by itself, I didn't need to melt it.


I am thinking about replacing my NB gauge with a lcd panel however, just makes it easier to glance over and see actual numbers and not trying to figure out what LED means what voltage which means what AFR.

Ha look at the site again....they have an LCD display now. :gay: after all you guyses bellyachin'...

I wonder if thats why lol. Adds alot to the price though :( and the supplied cable is way short.

I ordered the display kit as well
