EGT Probe
Anyone recommend a particular probe for MS. Looking to mount it in the manifold and don't want a big real deep one. The one i had seen before is now gone off their website.

I had a pre-turbo EGT on my STI (the probe is still there cuz I haven't gotten a plug for the bung yet >.>), and the tip burned/broke off the probe, and AFAIK my turbo is still fine. I haven't actually pulled it and looked at the turbine wheel, but the car still runs fine. I'm not sure I'd be too worried about going pre-turbo. And it's my understanding that EGT is really only meaningful pre-turbo, as close to the exhaust port as possible.
My probe came with my Zeitronix ZT2. I haven't replaced it yet, because they won't sell it without the extension cable that I don't need another one of. Last time I looked, there's a fair number of probes available on ebay, and you could probably find a probe from any gauge manufacturer that makes an EGT Gauge (like Autometer).
What does the MS do with EGT? Just log it?

Yeah it just logs the EGT. It will allow me to tune timing for lower EGTs. It would work in tandem with the knock sensor. I don't like the idea of tuning timing till you hear detonation or see specs on the plugs.

I've seen those. Thanks for the link again.
I like these.

Yeah, I was looking at the inconel 2000deg one at the bottom for extra lifespan. But I think some plug modification would be required for it to work with the Zeitronix cable, and I'm not sure if you can just bust out a soldering iron, because I think it's sensitive to the metal used in the connections. Or maybe the connection isn't that important, and it's just the cable that matters.

I think the length of the cable connecting the probe to the gauge/ecu is a calibrated length for the probe. Autometer warns that the cable should not be shortened or extended.
I'm using the long style probe in the collector of my greddy manifold. Pointed directly into the inlet, hopfully it doesn't let go! Reaction time is nice and fast.

What is a knock sensor going to tell you about dangerously high EGT from having timing too retarded? In fact the knock sensor and how the ECU is tuned to deal with it can cause EGT to rise. The EGT will help alert you to the problem.
You could have a perfect A/F, or even be rich and still run EGT that are dangerously high.
All of these things are tools for tuning. The knock sensor in my mind is less a tuning device and more a safety device.

Yeah I understand that. I would put it in #4 anyway just because it is closest to the firewall, thus the shortest amount of wire running through the engine bay.
I don't want EGT to tell me when I'm to advanced, that is what the knock sensor will be for.
I also still need to get a GM IAT and install it in my IC piping.
