As some of you may know, I build an 80mm custom AFR gauge as a clock replacement for 911s and recently someone asked me if it was possible to build a 60mm version. I was able to fit the main board and stepper movement in a 60mm case. This is just a prototype, but it does appear that with a little work, I could make these. It would require a 60mm temp or volt gauge as the donor to get the case, face, and needle. I don't yet have an estimate on the cost, but I wanted to see if there would be any interest before I spend more time on it.
Like all of my other AFR solutions, this gauge would work with most wideband controllers including but not limited to AEM, Innovate, PLX, and 14Point7. Sorry for the blurry picture! Attached thumbnail(s) |

I bought something like this for less than $15 (thanks to @GregAmy ) to use it with my microsquirt conversion (when I get to it... (IMG:style_emoticons/default/rolleyes.gif) ).
https://www.adafruit.com/product/1778?gad_s...uBoCWJwQAvD_BwE I think there are a few like this around. One would have to ensure it is temperature compensated (which I believe mine is). Now how to convert the 0-5V output in something that can drive a VDO gauge? (IMG:style_emoticons/default/idea.gif) Clearly the volt gauge uses the 8-16V range but how precisely? Then how to precisely bump up the interesting portion (250-450F) of the 0-5V output into 8-16 V for the VDO Volt Meter. That would be a question for the electronic gurus. (IMG:style_emoticons/default/smile.gif) Or, is the movement of the typical VDO gauges low voltage, something close to 0-5V? (IMG:style_emoticons/default/confused24.gif) One thing is sure, a good and precise 60mm CHT gauge with the same design as the other center console gauge would be a high seller. The larger the scale the better (like the MBZ span). Silver dot hand for me please! (IMG:style_emoticons/default/smile.gif) |
