GI: "YarGauge" replacement clock module (Digital Tach, etc.)
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? Note: Jump to post 512 of page 29 to see how this has evolved: http://www.yarisworld.com/forums/sho...=21909&page=29 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... Last edited by CTScott; 09-16-2010 at 11:55 AM. |
