Default EGT logging

So I have a new manifold with a bung for an EGT probe. I plan on taking the proven/usual approach using a thermocouple probe. The question is, what to use to condition the signal, and how to get it into the Adaptronic?

There are a few thermocouple amplifiers out there that will take an input and convert it to a analog and/or digital signal. Innovate makes one, but it has 4 input channels (overkill) and may not have a 0-5V out; I have not torn into the manual yet. Plus it is $130. Anyone got an idea on a good 1-channel TC amplifier, with a 0-5V output, that runs on 12V? Not looking to build a conditioner, would rather buy one off-the-shelf.

As far as how to connect to the Adaptronic, I am already using the serial port for the Innovate LC-1 WB02, so I think that is out unless there is a cheap and easy way to connect both at the same time. So I think that means I need an analog output from the TC conditioner to connect to the Adaptronic. Any suggestions there?

I poked around the Adaptronic site and did not see anything in particular. If it is there, I missed it.

Yeah forgot to mention the gauge thing. I do not have another spot to put one and really do not want to anyway. If I cannot find a way to log it, I will probably just use a handheld meter with a thermocouple reader, like at the dyno during tuning for example.

The adaptronic may not read an EGT natively, but if I can at least log the voltage I can always convert it later. Plus it will be synched with the rest of the logged data.

I think with the latest firmware you can log either the LC-1 OR the TC-4. It sounded like they were still working on being able to log both chained together. The nice thing about the innovate stuff is that you can hook up another usb/serial and log both.

I read that same post on the adapt forum just he other day. I'm not sure what is going on with it though as I haven't heard any updates. My contact Rob is out of the office this week so I'll have to wait until next week to get the scoop.

There is a $3 IC that will do it (thermocouple amp). I built one once. IIRC the IC was by Analog Devices.
