Here's a pic of the sensor. Added the bung after extending the IM neck.

looking good! I cant wait to see what numbers you get with that air to water intercooler. How much boost will you be running?

Also I have a Masi thermostat box on hold for you, would you still like it? I have three left.

[johnl]

Yes, I do want it. I'll be sending moola

Great! Please use office@exoticelectron.com for paypal. Thank you!

Asa, just ordered one kit from your site.
Thank you!
Plan to use for EGT on my TU header and for intake temp most likely.

got it thanks!

Wanted to give a quick update/ product review. (Edit: I just lost half of this and my pic when i first posted, but i think i have it basically all back. )

I brought my kit into work and we checked it out in the instrument shop.
Plugged in the gauge to a regulated power supply set to 13 VDC, and set up the thermocouples in a standard set to 20 deg C and a standard set to 600 deg C (the max of that equipment). (The standard is calibrated to +/- 0.3 deg C at 600 C)



So that was only 5-6 deg C off at 600 C, or about </= 1% error.
This checked the accuracy of the entire package, the gauge and the included thermocouples.
The reading displaying 594 was actually bouncing between 594 and 595 C.
(I didn't get a pic of them in the 20 deg C standard, but they both read 20 C.)

Next we looked at just the thermocouples, by plugging them into a thermocouple calibrator to check the probe accuracy.
In the 600 C standard the read 592 C on the calibrator.

Next w checked the gauge with the thermocouple calibrator by sending a known signal to the gauge to check its accuracy.
At a generated 900 C signal the gauge displayed 900, and at a generated 1000 C signal the gauge displayed 998 C.
So at 1000 C, the gauge error appeared to only be -0.2% (pretty darn accurate!)

600 C = 1112 F
595 C = 1103 F

All in all, I think this is a very good deal. I think the accuracy of the probes should be well in the range of usefulness for our applications.
Thank you Asa for assembling a quality product at a competitive price for us!

So I could buy two of these and get readings off of each runner? So one guage for say cylinder 1 and 2 and then the other guage for 3 and 4?

Thank you for the very interesting info wheming.

The gauge uses a very high quality, USA designed thermocouple sampling IC, and the processor uses a 112 point linearity compensating table based on NIST values to maximize accuracy across the full temperature range, this is how the very high accuracy of the gauge is attained, as you measured.

Standard type K thermocouple accuracy is a couple degrees C at best, which is plenty accurate for most measurements in an engine, since locating a temperature sensor of any kind of a few inches in one direction or another can change the measured temperature by 10 times that or more, especially EGT.

Yes you sure could! Two gauges could show 4 temperatures simultaneously!

Fixed my post.

So, I have one of these now finally hooked up in MeanMini. And i have to say, i like it!
I'm reading EGT at the TU header just before the turbo flange (already a convenient boss there that just needed drilling) and also intake charge temp (on Lengel plenum just after TB flange).

I think i want to order another kit to have and eventually get intercooler efficiency.

Asa, you still have any left in stock?

I soitenly do! I'll PM you the details!

Glad you like it BTW. Intercooler efficiency measurements is the main reason I designed it. I couldnt find another reasonably priced gauge that would do the simple math and show a live difference between the probes, along with peak detecting that difference. You can really get insight into whats happening when you can measure real-time temperature change across things. I havent done it yet, but it would be interesting to observe coolant temperature drop across the block. Or maybe even temperature drop across a header?

Wheming, TM says your PM box is full. So I emailed it to your stickman email address.

[wheming]

Cool Asa, thanks.
Sorry didn't know my box was full. I'll work on clearing some up today!
