Great, more brown trousers time then
. Mines curretly in mondo mode, if tats any kind of mitigation.

it still does quite a lot of work driving the front wheels and being a front diff too!
not trying to scare you, just pointing out the possible dangers of messing with the cooling system.
it's far from perfect in standard form but if well maintained it won't cook your ird/cause your heater to run cool.

True, and all these problems are eroding the apparent benefit values of the EWP, but if no one every experimented then we wouldn't have Freelanders eh .
Like all the times when I've done something new, you muddle about and it's a mess and then suddenly the penny drops it's simple, elegant and incredibly effective. I'm determined to get to that point with this.

its not a problem - yu have good standard ird exchanger in DDs to compare temps against .

Indeed, this IR Thermo is going to be very, very helpful in this endeavour - thanks for pointing them out to me MHM.

Just had a disturbing thought
if the heater isn't getting hot, is the ird heat exchanger working properly?
I thought about this earlier!! I think the IRD will be thermo siphoning through the heater at least some of it's heat which will help reduce it's temperature a bit, it's also not hot weather which will help too. It might be worth changing the IRD oil once the cooling system is sorted though.

Well as long as it comes out the same temp as yours we're ok.
So, where should we take readings? My thinking is:
- Upper rad hose
- Lower rad hose
- Heater inlet
- Heater outlet
- IRD casing
- Block
Anywhere else?
just a thought DD
if we all throw our ideas into the pot, that can only be a good thing

We is .
I reckon those temp readings are going to prove to be highly interesting.

if it can measured, it can be tuned

LOTS of EWP's fitted to Stags by the looks of things - figures. I may post up there see if they have any bright ideas .

Just sent an email off to DC about calibrating the sensor too. Right I really out to get some sleep now, my eyes are about to drop out of their sockets I've been at this all day.
Night all.

I got a reply from DC, they said I could attatch a 20KΩ resistor in parallel to the sensor. Ok so that's something, though surely the resistor would need to be different depending on how far out of calibration the sensor is? But hey it's something to try.

Maybe they know there is an error in some of the sensors and 20K is the correction?

It's possible. From my limited electronics knowlege, wouldn't it be best to fit a temporary variable resistor and then test the actual temp vs displayed temp over as wide a band as possible? Once you know exactly what resistance you need you can fit a fixed resitor to suit - assuming it's a linear coefficient anyway.
At the moment, as far as the system is concerned it's finding an equilibrium as best it can, however because the pump pulses at 6v, this causes instability at the lower end - even pulsing is too much to allow it to get to 85 degrees on the display - wheras actually it's trying to get to something like 105 and this is throwing it out because the fans won't let it get that hot. So in theory, if the what the pump is reading is a the real temp then it should find it's target and sit there.
I think...
