 Cylinder head temperature Anyone know what the ideal temperature is for the 2cv engine (late 602) to run at?
The Bedouin has an area under the grill that is allowing a large volume of air to over cool in winter. I need to block some off.
I can purchase a cylinder head temperature (cht) sensor, but it won't mean a lot unless I have some idea of what it should be.

Re: Cylinder head temperature Sensor under the plug approx 200 deg C, from memory??? In manifold see pics ps With the thermocouple under the plug are very fiddly to fit.

Re: Cylinder head temperature Thanks Pete I've ordered one (under plug), let's see what I get.  How did you calibrate?

Re: Cylinder head temperature Ungrounded needed you can then power the set up from the car supply. Start with this battery display https://www.ebay.co.uk/itm/TM-902C-K-Ty ... SwKeNd0gePPeter

Re: Cylinder head temperature It will take few days to arrive. However, I may have ordered the wrong type.  We will see. What I think I require is a resistive type. The same as a water temperature sender would be. I'm after connecting it into my Speeduino for when I'm running on petrol. I have this whizzy Android app to monitor it when running on Speeduino..

Re: Cylinder head temperature @What I think I require is a resistive type.
That will be a "Thermistor" used for Oil and Water temp (max temp approx 130 deg C.)
"TC's" (Thermcouple) signal gives Mille volts but can measure very high temps eg exhaust.

Re: Cylinder head temperature Thanks Pete I did a little more research last night, and it needs an amplifier. Its ordered it will be interesting connecting it all up.

Re: Cylinder head temperature Did a quick search for EGT on Speedunio but didn’t find much, what did you find re amplifier with Speeduino ?
