I wonder if anyone has ever tried to connect 1 gauge, CHT that is, to 2 cylinders. I can envision the leads coming from the spark-plugs connected to a toggle switch or some type of selector switch and then on to the gauge. Switch to the right, and I get the temp of the right side, switch to the left and I get the left side temp. Could it work? Did I read somewhere that the length of the wire has something to do with the accuracy?
I know there are gauges out there that will show temps on all 4 cylinders, but I do not want to invest that much. Just looking at the VDO CHT gauge. Any thoughts, Clark |

Here you go, take your pick
http://www.aircraftspruce.com/menus/in/chtgauges.html Westach is good enough for our cars but it was an entry level gage when I was flying. Our CHT thermocouples only produce about 2Mv so any changes to the original loom will result in some crazy readings. Remove resistance (trimming wires) and the indicated temp will be higher than actual temp. Add in resistance (splitting, soldering additional length's) and the indicated temp will be lower (if it even registers). |
