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

[CTScott]

A while back there was a discussion about converting the clock on the cluster to a digital tach. I have been exploring this a bit more and am looking at creating a replacement module for the clock that would have an 8 character display and would allow you to switch between the following functions (using the same push button that is used currently to set the clock):

1. Tachometer (RPM 9999)

2. Diagnostic trouble code read/reset (DTC 9999) (If more than one code is present it would scroll between the stored codes). Holding the button for 5 seconds would clear the stored code(s).

3. Water Temp (WT 999F) or (WT 999C)

4. Battery Voltage (VOLT 99.9)


And, probably a few more. Maybe even MPG (instant and average), if I can figure out how to calculate those from the available data.

It would remember the last display choice and F or C for temp.

Installation would require popping the cluster out, removing the clock module (a separate chuck held to the back of the cluster with some tabs), disconnecting the clock connector, replacing the clock's circuit board with mine (pop a couple of tabs and remove two screws), reconnect the clock connector to my module, and tap four wires onto the other cables going to the cluster.

Target price would be $75. The question is at that price, would there be enough interest to make it worth my time?

The original price estimate was based on using an very inexpensive display. Through my development testing I found that the cheap display (and a couple of other more expensive displays) just wouldn't work well with sun glare on the cluster. In my quest for a better display to combat this issue, I settled on a high-end, full color OLED display. The chosen display unfortunately costs $79, which is more than the original target price, so the current target has moved to $150-$200. This additional cost did bring about some great features that were not possible with the cheaper displays...

Wow what a great idea would be very oem. I was just expecting it to be tach but if it has all those features 75 isn't bad all.

I think $75 is very reasonable. You might consider adding an automatic function to switch between the different readings every few seconds.

As for calculating MPG from available data, I found some sites on the net that discuss it only I can't remember the site name. It may have been from MP3Car.com or some OBDII developer site, but it is out there. If I can find the link (I think I have it bookmarked on my laptop) I'll post it.

that sounds awesome! ***I voted on the poll and it sent me to another thread***

$75 sounds great. I've been contemplating how to do exactly what you're talking about.

Ummmm yes.

i'd certianly save up for one of these. i could sell my voltage meter to it :)

I am in

I'll take 25. Whatever guarantees you'll make this, it's the coolest mod I've heard about in a long while (and I can't even use it for myself )

[ezhacker1]

how bout see if you can get (miles to empty) im curious to what other features you can implement, would be better than a SGII just cuz its oem looking.

And as we know that you are very well educated in electronics and stuff, we wont just get our hopes up. Man im excited.

Would the clock function be preserved and be one of the functions you could cycle through?

Possibly. That's why I put the "I still want the clock" option on the poll. Adding the clock is not a huge deal, I just wasn't sure if people would still want it.

[kustom play]

i would be down for one

[GMKing]

at 75 dollars i'd buy that right now

[1NZYaris1]

Doh me bad i voted in the wrong box , i would take one .

[lilredrocket]

Do it!!!!!!!!

[ezhacker1]

question: would this interfere with say my Ecometer? seeing im guessing that your module whatever would take signals from the obd2. Im not all that knowledge about the matter, but i read on other forums when searching, that 2 devices getting signals from same source would show errors on one of the devices. Now to me i just thought that splice the obd2 connector, have 2 female ends = 2 devices.

I just dont want to give up my ecometer.

i'm in for one!!
