GI: "YarGauge" replacement clock module (Digital Tach, etc.)

That's correct, since the clock is not a separate module, like on the tachless ones. I am trying to figure out where the YarGauge could be integrated to have the OEM look for tach equipped liftbacks and sedans.

Oh that sucks. I was totally going to buy one but didn't know the new ones came with a tach lol.

For 2010 all manual transmission LBs come with the tach. Autos still do not.

Still want me to take some pics of the inside of my cluster? I have one with a tach - just tell me what you need a pic of and I can do it tonight.

I actually have one on my test bench. I don't see being able to mount it within the tach cluster without modification, so I am looking for someplace outside of the cluster. For example, one thought is to mount it in place of one of the center AC vents. I am open to suggestions.

I obviously could mount it in a small enclosure, that you can put anywhere (like the scangauge), but that diminishes its value versus products like scangauge.

Alright then. I am going to look tonight to see where would be a good place to mount it (for me anyway).

One question though: since we can't replace the clock module, is hooking it up going to be more difficult? IE: are more spliced required?

You'd have 3-4 more wires to tap:

Ground, constant power, switched power, and possibly dimmer.

To install the proto on my 09 w/out tach, I only had to tap one wire (outside temp sensor), as I realized that the two can bus connections could be made to two test points on the back of the cluster.

Does the '09 5-door LB have a built in temp. sensor? When I installed my CIPA rear-view mirror w/ compass, temp. and map lights, I had to install a temp. sensor. I clipped that to the bottom-most grill on the front bumper.

Yes. All Yaris with AC have it. No aftermarket device would interface to it though, as it isn't universal enough.

[devinlamothe]

I was thinking of putting it in the plastic covering by the wind-shield washer lever - you know, the one that covers the hole for the push start button?

I could get a rectangle shape laser cut, then laser cut a piece of thin plexi-glass to glue onto it, then put the screen below. That way the wires can run through the hole, and I could still see it while driving.

Not the best solution but I think that is where I am going to place mine.

About time, but I wanted all the other cool functions too lol. Can't have everything I guess? lol

Scott, your product is 50x cooler than the scanguage and developed IN HOUSE SPECIFICALLY for people who own Yarii. That makes it more enjoyable and rewarding to own and use.

For example when people get in my car I proudly tell them that some crazy CT electrical engineer fabricated up a switch for my airbags.

This is a great project and you shouldn't fear the scangauge because yours is going to be way better!

Also, as an owner of a tach, I would like to see a version of it fit under my single DIMM head unit or as an AC vent replacement, both are great ideas.

Good idea!

Awesome work CTScott, it's looking amazing :) for this

Update: 1/20/2010 - Final design review and testing:

After installing the proto in my Yaris and driving around with it for a week, I found that bright sunlight was a major problem. This time of year, most of my driving is either in the dark or on overcast days, so it took a few days to encounter the worst case conditions.

After speaking with some display manufacturers about the issue, I was able to find a different type of display that is far more sunlight readable. I explored many options, including many that would have doubled to price of the product. The display I finally chose fits better within the space, so it is not recessed, as the original had to be. Also, the text is black on white or orange (other colors will be available as well), so the display is similar to the fuel gauge, rather than the original clock display.

YarGauge - 0120.jpg


Here is a list of all of the current features. If there are any additional requests let me know ASAP, as I am preparing to cut the final version of the circuit board.

1. Clock and outside temperature on second line.

2. Display modes for top line:
a. RPM numeric
b. RPM bargraph
c. Fuel Economy (MPG)
d. Battery Voltage
e. Coolant Temp
f. Intake Air Temp
g. Fuel system status
h. Calculated Engine Load %
i. Throttle Position %
j. Speed
k. Number of stored DTCs
l. List of DTC's
m. Clear DTCs / Reset MIL (Check engine light)

3. Programmable Shift Indicator / Light - This optionally displayed feature will display an indicator between the time and temp on the second line. Considering the small size of the display, this feature will also have a 2 wire output that will drive your choice of LED, mounted wherever you choose.

4. Cruise Control Indicator - For those with 06-08 Yaris, who have done the DIY cruise control, this feature will display an indicator between the clock and temperature to indicate that cruise control has been activated. This will require a one wire connection to your DIY switches or OEM CC stalk.

5. Automatic Dimmer - The new display is much brighter than the original, so I found that I absolutely needed the dimmer feature.

6. Configuration options
a. US or Metric units
b. Time display - 12 or 24 hour
c. Shift light enable/disable
d. Cruise Control Indicator enable/disable

Scott enough already!!!! All of YW can't wait anymore release it

Wow amazing work, thanks for making this all happen and for making it at an affordable price. I would expect to pay a few hundred if this was offered from anyone else. Much respect my dude.

1) how does the user give it instructions ?
