Could anyone with a Nanocom and post 99 car with MAF and EGR take an external air temp reading for me and see what you get? It would put my mind at rest and if you also get -38.88 (or similar) save me shelling out for a new MAF - or if you get a decent reading, it'll tell me to go and buy one!
tnx

I don't have Nanocom but Faultmate is supposed to have the same sortware I'll take a look later. You don't mean external air temp though do you? You mean inlet air temperature.Could anyone with a Nanocom and post 99 car with MAF and EGR take an external air temp reading for me and see what you get?

No idea about pump modulation. Still learning. I'll have a look for that option.
Surely you're talking intake air volume and not temperature....Have you actually had the maf off and cleaned it around the hot film with electrical cleaner to remove any oil deposits . The air temp on the nano is the maf whatever setting its at it should increase with the revs take it for a drive around and check that is rises if it doesn't its duff it should increase to a maximum of around 150 and be between 30-50 at idlel
Well, as air passes across the mass air flow sensor, it cools the hot wire, increasing the amount of current needed to keep that wire at the specified temperature. The amount that the wire is cooled is directly proportional to the temperature, density and humidity of the air passing through the sensor and as such, the current increase needed to heat the wire allows the computer to easily calculate the volume of air entering the engine.
IAT doesn't exist on the MAF equiped vehicle the reading does not change.
It is an unused input as the sensor doesn't exist, it's mentioned in the info somewhere, it does not change, I've just checked it on my car.
Frankly I've no idea what he's talking about, the only figure that will change is volume not IAT.
But its the volume of air that the maf registers forget pre maf cars nicks Is maf the more air the cooler the the sensor the sensor has to increase its heat and that's where the readings rise don't see how you can Check it on yours data your pre egr are you not .Frankly I've no idea what he's talking about, the only figure that will change is volume not IAT.
Pre MAF cars needed IAT to calculate density for fueling
2001 MY Faultmate MSV 2 Extreme, look at my signature so quite easy to check.
Yes that's the fuelling side but how does the sensor work and its readings its heated and the more/ faster the speed of air will cool it so it increases its self and the fuelling to match the air thus that's how you read weather the sensor is working if it isn't increasing its self nor registering the air flow thus no increase or any rise in the nano' s readings are you saying the nano hasn't the capability to read the maf sensor to be honest I don't know what your all trying to get at .
You are confusing the IAT reading with the MAF reading, IAT does not exist on the MAF car so the reading in the box cannot change, Nanocom and Faultmate work with MAF and pre MAF cars, the IAT box refers to pre MAF.
