I am thinking of getting an Automerter Ultra-Lite EGT Gauge. My problem is that it only goes up to 1600 degrees F. I thought turbo engine recommenced EGT's were between 1550 and 1650 degrees. Is this true and if so will it fry my autometer probe?

Problem 2 is a friend of mine fried his probe on a WRX , I am wondering if anyone has installed an Autometer and had any problems with it.

I am thinking of putting the probe 1 inch from the head on the number 3 cylinder. I have heard that the #3 cylinder is the most likely to go lean, is this true? Which one is the #3? Figure I would monitor the weakest link.

Anybody have any thoughts or suggestions, they would be greatly appreciated.

 

where is the #3 cyclinder?

 

I'm also running the utra-lite
mine only lasted about 2 months

mounted it on the cross pipe.
Usually topped out at about 1450.

worked fine for a while but now only registers on cool down when I let off the throtle. It peggs back to 0 anytime I touch the gas.

 

I'm installing an EGT gauge and I've heard that cylinder 3 is the hottest, I'm just not exactly sure which cylider that is (I think the back one on the right side when you are standing in front of the car looking at the engine bay)? I've also been told to mount the sensor 3 inches into the header, is that true? Thanks for any help.

K2skier - I don't see where your information is any different than Steppin Razor's??? You are both saying 1650, assuming location is in front of the turbo. His point is that if 1650 is the point you are concerned, then a gauge that reads 1600 is useless so get one that reads higher like 1800 or 2000. As you approach the high side of the gauge it becomes less accurate any gauge that is pinned isn't telling you anything.

FatJoe - it depends on which numbering convention the person is using. Some say #1, some say #3. The point being that the last cylinder on the fuel rails can get fuel starved and run hottest. It is that cylinder that they are all referring to. And yes if you want to monitor the temperature at a cylinder about three inches from the head is the proper location, you definitely don't want the gauge any closer to the port than that.

I personally prefer Omori gauges, though Defi link definitely has some great functions. I would consider Defi if they expanded the gauge selection that could be used on their link system.

 

Thanks for the info, the installation went great, I simply took down the plastic cover on the bottom of the car, took off the heat sheild, then the manifold off cylinders 1 and 3. Then I drilled it with a 5/8 drill bit, tapped it with a standard 1/8 pipe fitting, screwed the bung in, dremeled a hole in the heat sheild to run the wires, and re assembled everything. It was not as hard as I had initially thought it would be. Thanks again for all the help.

I have the Autometer Ultralite and it has never even been close to 1600. I believe I got it to 1400 at the drag strip once. If you read the installation instructions Autometer suggest that you install the bung before the turbo in the up-pipe very close to the turbo. Mine is about 1 inch from the turbo.

 

number 3 piston is the one next to the up pipe or in front of the passenger firewall. thats the one i tapped into.
