I read that earlier too...I think it is in error as it is written like that for the 1997 Electrical circuit operation too, apart from the 1997 version mentions a default reading of 30degC if the IAT sensor is duff....
saint you been trawling as well :) I try to never give up ;)
Wish I could copy and paste with my version too:(

Mine has MAF and EGR and my nanocom says -38.8.

That's 3 out of 3 so far (2 on this thread and one from another thread)

So it looks like it's meant to be -38 on a MAF because the diagnostics is reading a sensor (IAT) doesn't exist.

I'm happy with that. Still don't know why it's not a common question on Google "why does my air temp show -38" but still...

An interesting thread :)

and what of your fuel temp does that rise when everything has warmed up that shouldn't be minus 14 ?

Are you coming to the conclusion that it is a preset yet? Either that or both Nanocam and Faultmate are wrong.

no just don't work on the egr as it hasn't got the air temp sensor as in non egr bet it would work with that but now I need to get one soon then I can test both seeing as we own both types :)

Ok do that and see what comes up. There is no provision on Nanocom or Faultmate that i know of for reading MAF outputs. But the MAF measures the air temp going through it. It has to so the ECU knows the air density and therefore Oxygen content of the charge so it can adjust the EGR valve. Cold thick air more EGR warm thin air less EGR. The temperature of the air has to increase as it is compressed in the turbo therefore the actual inlet air temp must be extrapolated by the ECU from a combination of sensor readings for fuelling purposes. The engine cannot be fuelled from the MAF temp alone because it would always be wrong. As i said before, wearing a top coat in Benidorm because it is cold in Glasgow.

Not for the maf the air temp fitted to the non egr I can only assume it works on that
 
Can does any one know what system rovo com is I'm being told that maf readings can be read with this ???? I haven't a clue what rovo com system is

The Rovacom was the precursor to the Faultmate systems...

Was made by Blackbox Solutions....can in two versions - Standard and Lite

3 versions - Rovacom Pro as well.


ROVACOM PRO (July '04 to June '07)

Introduced in 2004 to build on the success of ROVACOM LITE, but for business use, the ROVACOM PRO came with a cool mini Tablet PC and featured built in Wi Fi connectivity. Production of the hardware ceased in June 2007.

ROVACOM LITE (July '03 to June '07)

Specifically designed to bring professional diagnostic access within affordable reach of private owners and enthusiasts. Using any old PC and innovative web based technology it was a huge success only replaced by the identically functional but more cost effective FAULTMATE SV in June 2007.

ROVACOM (Feb '99 to July '04)

Our first ever system began development in late 1996 and when launched in early 1999 it was the first ever Land Rover diagnostic system available to independents. It was designed to not only rival Land Rovers own TestBook system but to beat it hands down and is based around a very heavy duty and simple to use custom designed tablet unit.
 
Here it is sorry it's small

I am not talking about the none EGR engine. Obviously the IAT sensor can be read but the MAF can't. As for your other post Nanocom will read MAF on petrol engines as will Faultmate and Rovacom but not on the diesels. They will tell you if it's showing a fault but there is no live data readout.
