JAW Wideband???

[Anonymous_User]

there is a write-up "over there" about assembly and installation of a JAW wideband. First I had heard of it.

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

Looks like everything to assemble the latest version (including the sensor) would run in the neighborhood of $125

According to their website/forum you can datalog rpm and AFR or LAMBDA (built in RPM pickup). One 0-5v programmable output. One 0-1v programmable narrow band simulation output.

Had digital readout that can be mounted wherever and you can chain together up to four digital readouts to display: AFR, EGT, RPM, Boost


Hmmm.... very interesting.

I did not see on their site that the sensor is included? Not a bad price tho

There was another thread about this over here. The guys were saying the refresh rate if you will isn't fast enough. It was about 4? Months ago now.

Not included.

[quote] You will need to purchase the following to complete the kit. Before you order the components it would be a good idea to read this first for mod ideas.

-Bosch 4.2 LSU Wideband Sensor,
-Harness for sensor if you do not want to use the included terminals
-EGT Probe
-Wires, use multi stranded with a rating of 3 amps
-Component List for JAW 1.041, I recommend you buy them from www.futurlec.com as they offer the best prices. The cost of the components is ~ $10 USD
-Components List for Display 1.01, the cost of the components is ~ $6 USD.
-The case is available from here for USA and here for outside USA


The kit is 37.50 for:
JAW 1.041 PCB
Preprogrammed Atmega88 Microcontroller
14 position screw terminal
Heatsink screw
6 terminal connectors for connecting to Bosch Sensor
PTC Fuse
Button
62 ohm resistor

The display kit is 17.50

Damn, don't suppose I can use "JAW" as a search term as it is only three letters.

I'lll read up on their forum and see if there is anything about refresh rates in the latest firmware update.

I've heard they aren't very accurate.

spend a little more and get a better wideband. Sometimes it doesn't pay to be cheap.

It samples the O2 fair quickly from what I remember

There are a few TDers using JAW.

i have one in my lebaron and its great
i bought a complete unassembled kit with display for 85 shipped.
it uses a bosch wideband from a 98 or later VW turbo beetle, and yes its accurate as long as you calibrate the sensor properly before screwing it into the exhaust pipe. i bought the sensor for 37 bucks new off ebay.
the refresh rate is adjustable by the way. displays either A/F or Lamda, and it will datalog 2 additional inputs, RPM and another of your choosing. also has a selectable output so you can ditch your factory NB and have the JAW send your ECM a much more accurate NB signal from the wideband. and you can adjust the output voltage as well, eg; send a lower or higher voltage signal to make the computer send more or less fuel . the newest version i believe has more datalogging inputs and one more output.
assembly was easy- kinda like doing paint by numbers if you will, and the display is very easy to mount just about anywhere. i ended up cutting out the message center panel, and ghost mounted it behind smoke plexi. would look factory if i had a digi dash, and its nice and stealth too- you dont even see it till you turn the car on. i'll try to post pics as soon as i can find a digi camera to use.

It sounds like it is certainly something to consider.

Does anyone have any more/new info on this device for a "new", budget minded member?

I especially like the part about

also has a selectable output so you can ditch your factory NB and have the JAW send your ECM a much more accurate NB signal from the wideband.

im thinking about buying one for my daytona. i have a EGT sensor for the car but no gauge so this would work well. plus i dont feel like taking my wideband out of the k car.

It seems inexpensive, and if I could run just a wide band instead of a narrow band and not have to make a second location for a WB o2 sensor. Have more accurate data for the lm to read and for me to tune? it seems to good to be true. Am I understanding this right?

[Aries_Turbo]

you can run the wideband instead of the narrowband and send the widebands simulated narrowband output to the LM.

you have to run the wideband further down the downpipe though cause it gets too hot in the swingvalve housing for the wideband sensors. just put a plug in the narrowbands original hole.

TBone on TD, not sure if he is on TM, has had good success with running one. I have one here. I have not installed it yet, as my exhaust evac is above the WB O2 bung and I have not corrected that yet. But once I do, it is going in.

The turbo ford guys jumped all over them a while back and then started saying they were turds....just from what I've heard.
