EGT from the EGR inlet

Anyone using the output from the EGR inlet sensor to get EGT using the ScanGauge II? Would this be "close enough" to use for EGT? I'm trying it but it seems to run higher than I expect. It will get above 1300 climbing a small hill and runs around 750 on level ground at 65mph. Doesn't seem to go below 360 after idling for a couple of minutes. I am about to start towing my 8000 lb 5th wheel and would like to have the EGT info. if I could get it with the ScanGauge.

Come on. Someone tell me I'm full of it or the EGR1 will work... Please?

I have the Scanguage II and my EGT normally runs 400-500 not towing and 550-750 towing a 7k travel trailer on flat ground. I can't remember ever seeing anything over 800. I shut my truck off after the EGT drops to below 400, so I don't know how low it will go just idling.

69stang, are you using the EGR1 sensor, if so, what are your ScanGauge program parameters? Maybe I've got my MTH wrong.

wargle, I also programmed the EGT using the X Gauge function of the Scangauge II Ford Specific XGauges : Linear Logic : Home of the ScanGauge I would double check the numbers and make sure they are correct. It can be so tedious programming it that way.

I have the gauge plugged into the OBD port, so I'm not sure if it uses the "EGR inlet sensor".

The 6.4 has a EGT probe from the factory, its in the passenger side up pipe. It should read in the 300-400 degree range after idling for a few minutes. The other sensors are just DPF temp probes, those are useless for what your after.

Eric, ,That's the sensor/probe I'm talking about. I have programmed my ScanGauge II the the x-gauge for the temp sensor in the turbo up pipe, but, like I said, I'm not sure it's reading accurately or if it is a good source for EGT. This is the X-gauge I'm using:

TXD= 07E022115F
RXF= 04620511065F
RXD= 3010
MTH= 00090032FFD8

If your reading the one in the uppipe thats the one you want, its very accurate and is the same one the tuners will reference for the EGT reading. What temp are you seeing at idle?

After driving 55-60 and idling for a minute, it will read 375-425. I've noticed that it will hit 850 or more going up a slow grade at 60 mph unloaded. It seems to increase very quickly if you mash the skinny pedal. I'm just concerned what it will be when I start towing my 8000 lb fifth wheel up hills.

Sounds like its reading correctly to me, you just don't want it to get hotter than 1200* for longer than 15 - 20 seconds or so sustained. Thats when you can start damaging some parts.
