Advanced Cylinder Head Temperature Sensor by Vairtrix
The CHT-100 is an advanced Cylinder Head Temperature Sensor for the Corvair Spyder and Corsa models. Designed as a direct replacement for the obsolete AC Delco Thermistor, the CHT-100 uses thermocouple technology for reliable and accurate temperature measurement over the wide range of temperatures experienced in the Corvair air cooled engine. It uses your existing Spyder or Corsa dash gauge for a stock look with upgraded performance.
The CHT-100 uses advanced digital technology to convert the thermocouple measurement to a constant resistance source, matched specifically to the Corvair dash mounted cylinder head temperature gauge. It performs sensor linearization using tables published by the National Institute of Standards and Technology (NIST). The CHT-100 includes Cold Junction compensation to maintain accuracy over a wide range of ambient temperatures. Finally, the output of the CHT-100 is matched to the unique non-linear response curve of the Spyder and Corsa dash gauges. The result is a sensor that outperforms the original AC Delco design and provides an accurate temperature report from 200 to 600 degrees Fahrenheit.

My name is Pete Faulkner and I live in the DC area. I bought my first Corvair, a ‘68 500 in 1973 and have had several since. I currently own a ’63 Spyder, purchased in ’88 and restored in ’94. I have been a member of the San Diego and Northern Virginia Corvair Clubs.
Frustrated with the supplier community’s lack of progress in coming up with a suitable replacement for the Corvair Cylinder Head Temperature Sensor, I developed the Vairtrix CHT-100 with the goal of accuracy over the entire expected temperature range. I didn’t feel it was necessary to examine or reproduce the GM sensor as its accuracy is rather poor. It would have been akin to reproducing leaky push rod tube seals by seeking the original formula for neoprene. Instead, I focused on the gauge and set out to design a sensor that would line up with the unique characteristics of the Corvair Spyder and Corsa gauges.
I believe I have hit all of my design objectives in this first version. My only concern is long term reliability and time will tell if I have achieved this goal. In my past life, we did reliability predictions using software modeling and accelerated life testing in the chamber. Instead, I’m relying on a small loyal group of folks within the community who actually drive their Corvairs to serve that purpose.
Jim Simpson was gracious enough to send me his gauge curves and I referenced them for the firmware lookup tables. The fantastic people at the Corvair Ranch have provided support and together, we are conducting field trials.
My fiancé’ Misti owns a Graphics Design and Marketing firm and she put together a Corporate Identity, Logo and a web presence. She does this stuff in her sleep.
For those of you that may question my street cred, I have been a Corvair owner since 1973 and possess over 35 years of experience in developing sophisticated military and automotive electronic systems with high survivability that are used in the harshest of environments. Formerly, I was a member of the Institute of Electrical and Electronic Engineers (IEEE), the Society of Automotive Engineers (SAE) and the National Defense Industrial Association (NDIA). I am now retired and doing this for the Corvair Community as a hobby
Turbo pressure retard units now in stock
We have recently reproduced the turbo pressure retard units as well as the combination advance/retard unit that many people like to use.
