Hook me up too.

count me in.

I'm in. Thanks Laust!

I guess I've been screwing around over in OT too much.

Laust, I'd like one and I'll be connecting it to the ZT-2 also. PM enroute.

I'm interested. So all one needs is the gauge now? Sorry if that's a stupid question.

Yes you need a gauge or some device to measure the output from the probe. Here's a picture of mine from an old thread:

EGT gauge

Hi Laust, please put me down for one as well.

On an unrelated note, how sick is it that the thing I'm most jealous of on RK951's setup is how good the white graphics are on the mirror and sunroof buttons? LOL.

Laust, please count me in for one unit. Thanks for doing this.

me to please

any update on this?

I have to ask what the point would be of only one EGT probe, let alone one so far down the line? EGT's are used to monitor the differences between cylinders so that you can see when one has a problem. Very common in aircraft, it's a great way to see a problem coming before the fan on the front of the plane actually stops spinning (the world sure is quiet up there when the engine stops). I guess I'm just so used to 4 or 6 egts comparing the health, mixture etc across the motor.... I can't see the point of just one.

Count me in for one as well. I will have all that out of my car this winter anyways

Bill, it's a level of practicality.

Laust will be doing a test run in his car with this new probe, then compare it to the exixting individual probe readings for a ballpark figure, which for many is better than nothing.

I am in the middle of making parts and probes will be ordered on Monday. They should have a 1-week manufacturing time, so it looks like I will have everything ready by the week of the 20th and will at that time notify each of you via PM.


In addition to what “ibkevin” said, there is certainly a huge cost savings by using 1 vs 4 probes and associated electronics/gauges for monitoring. Installation convenience is another factor.

There is more information in a 4-probe system, but with only 4 cylinders it should be possible to see only one cylinder acting up using one probe.
Under the (normally good) assumption that all 4 cylinders are fairly uniform the 1-probe solution is a good verification tool for AFR adjustments (and AFR deviations).

As mentioned, preliminary comparisons show that the two methods give about the same measurements with adequate exhaust flow, which is really where you want to monitor the temperatures anyway.

Nice one Laust.

Rather than using a gauge, would I be able datalog the output? ie is it a 0-1v or 0-5v type output and if so is there a known correlation of output to temperature?
