REFLECTOR: Dynon -Oil Temp Sensor

[Ruben Creus]

Scott, 

Well, the sensor is made by Grand Rapids, which is a direct competitor of
Dynon, so maybe they do not want to make so public to avoid admitting that a
competitor had a better solution for an oil temp device. Anyhow, they
finally told me that this should work. I tried it and since is just going
perfect!

NOTE: Remember that if you use this sensor you need to change the oil temp
sensor type in your Dynon configuration to TYPE 3


Here is the info of the sensor

Part Number: GRT FT-LC-01

I bought it from Chief. Here is the link.

Price $19

Hope that helps.

Rueben,

I've been dealing with the exact same problem!  I wonder why they didn't
mention a two wire sensor to me?  

Do you have the part number?

Thanks

Scott
