Micro1000 CHT Gauge, my preferred setup Options

[McMark]

I was asked about which CHT gauge to get and thought that I had posted this info about the Micro1000 over here some time ago. Apparently not. (IMG:style_emoticons/default/rolleyes.gif) So here's my preferred CHT setup because it has an original looking appearance, it's temperature compenstated, and the sensor and wiring is QUALITY stuff. The temperature compensation is important because the crappy VDO setup (and other cheapies) will read 1° off for every 1° above or below 70° inside your car. The VDO wiring can also lead to erroneous readings due to how the thermocouple works and what are called 'cold-junctions'.

CHT Gauge

This is the Micro 1000 gauge as mentioned. It ranges from 0-600 degree F or 0-300 degrees C. The top row of numbers is F, the bottom row is C. It's got two thumbscrews on the back for the collar that will hold the gauge in the dash (or wherever). It comes with a bulb assembly included for night visibility (I forgot to take a picture of that). The back has a + and a - connection for the wire extension. You want the 2" version.

Sender
You will need to buy the appropriate probe/sender for your application. A standard Type IV spark plug is 14 mm. The smaller plugs that Len is using is a 12 mm motorcycle spark plug. I can't vouch for which sender should be used for this application. The sender only comes with about 12" of wire. You will need to purchase an extension lead (see below). The sender comes with a section of heat shrink tubing to protect the screw connections between the sender and the extension leads. The section of wire close to the heat source is protected by a braided wire exterior. This is a very nice feature. (IMG:style_emoticons/default/biggrin.gif)

Extension Leads
You will need to purchase either the 7' or the 15' CHT extension lead (make sure you don't accidentally get the EGT leads). These are special wires. You can not use normal copper wire to extend the wires. The wires come pre-crimped with the appropriate connections. So it's a simple plug in installation. I purchased the 15' kit for my 914 as I suspect the 7' is too short, unless you're doing something unique.

I'm very happy with the Micro 1000 dual needle setup that reads CHT on #1 and #3 cylinders.
