The Pyrometer guage is one of the guages that I am going to install here in a couple weeks. I am going for the Autometer #5744 Phantom steet series electrc kit. Where is the best place to mount the sensor? I do run longtubes and I recall that someone stated that he had the sensor on his stock exhaust manifold next to the #5 cylinder. The "Research" didn't help me find anything useful.
Thanks for any help.

 

I have the same Autometer EGT.Yes, mount the probe as close as possible to the cylinder head on the first port on the driver's side.I've been told by one of the Tuners this is usually the leanest.
I had a local muffler shop do it for me.They quoted me $20,then realized they would have to remove the manifold and asked for anextra $50.The tech said it was a real BITCH!Glad I paid the extra $$!
Let me know if you have any more??

 

I installed the sensors in the #5 and #4 exhaust tubes. I tried to get them within 4" of the exhaust port in the head and close to the same distance from the head so I could compare temps. I have a dual egt gauge from autometer.

 

 

I hsaven't had any leaking from where I just taped into the headers. I suppose I could have welded the bung...

 

OK, another ?
About the Probe, what is the difference between the Competition (#5244) and the Street Series kit (#5249)???

(edit) Oh, that is for a 2 channel guage.

 

The optimum location for the EGT probe is about 1 inch from the exhaust port. The farther you get from there, the readings get a littled skewed, but should still work ok. There are two kinds of probes, clamp on, and screw in. The clamp on kind just requires a 3/16" hole drilled in the pipe, and can be done on the truck. The fitting kind will either have to be drilled and tapped or welded on depending on the style you have.

Remember, EGTs SHOULD NOT BE USED IN PLACE OF AN AIR/FUEL METER!! EGTs are a great tool for monitoring your motor, but should be used in conjunction with other methods of datalogging. There are too many variables that affect EGTs to use that reading as a stand alone tuning device. Over time you will learn how your truck responds in different situations, and you will learn just how the EGTs can help you. But do not slap an EGT on your truck and use the readings to adjust your chip, unless you are experienced in doing so.

 

Lightning tuner took the words right out of my mouth. You should always base your tune on a wide band O2 setup up and not an EGT gauge. Once your truck has a proper tune you can use the EGT to monitor your engines performance. Your EGT temps will not be constant and will depend greatly on tune, mods, air density, fuel, etc. They can be a great aid if you log the information they present but they can "fool" people into messing with the tune of a vehicle and damage can result.

That came across my mind for a split second, but thought that would work as far as a stand alone system. I know it won't now.

Well would running the air/fuel guage also help any or would I be wating my money?

I already ruined one motor, I don't want to ruin another...especially my new built motor.

EDIT: Lightninfun said just what I was curious about. I was thinking that would work.

 

What Sal said.

 

Yup, what Sal said. But, the EGT guage is a very nice guage to have. That guage, in tandem with the fuel pressure guage helped me find a fuel delivery problem (split in-tank fuel line) that appeared several months ago and was causing the truck to go lean.
