Eric, I would think that the software would need to be rewritten in the IPAC to show the real temp readings?

If somebody would be able to come up with that solution, I am a buyer. Don't like this blob we have now. Would love to see the temp gauge show the real thing from min to max so that we can adjust our driving when necessary  You never actually own a Defender. You merely look after it for the next generation.

And by the way, anybody knows what is the "ideal" coolant temp for our Pumas? I know with Mercedes they say this is 82°C.

Mine is 89-90 degrees with normal solo driving.

Humm, I wonder about this coolant vs. CHT temp reading.

Assuming the water temp reported by the Scanguage is actually not the water temp but the CHT, I would expect the CHT reading to match the water temp (since they would be from the same sensor), right?

Well, that's not the case here. I usually read CWT (as reported by the std gauge on the SG) between 88/92 Celsius whereas CHT is much higher, usually between 95 and 100 degs Celsius, as reported and computed using the formula I posted here http://www.defender2.net/forum/post151519.html#151519

If that formula is wrong (which is obviously possible), I would still expect both values (CWT and CHT) to correlate perfectly. but that's not even the case, both values vary differently (but not complete opposite of course, they still follow the same trend), so it looks like different temperature readings from different sensors.

Please let me know if/where I'm wrong
