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.

I'm not sure the adap does EGT natively... how bout a gauge?

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.

OK Travis let me know what you find out. Thanks

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