Cylinder Head Temp Gauge Recomendation Options

[ddc829]

Can anyone recomend a good cylinder head temp gauge and source?

Anyone seen a blue tooth version that can be monitored with a smart phone? I use the 123 dizzy app to monitor engine conditions and really like not having to mount additional gauges.

Highly unlikely within automotive or aviation marketspaces. The biggest consumer of CHT gauges - general aviation air-cooled engines - are all hard-wired into either gauges or engine monitoring systems.

However, you may be able to find an industrial solution for bluetooth monitoring of a thermocouple system. A quick Google revealed this:

Looks like it also does data logging.

If you're handy with electronics and apps, you can design your own. Use this amplifier:

...to convert the K-type thermocouple to a 0-5V analog output, then some kind of BT transmitter to convert that to an app.

I use that amplifier to input CHT into my Microsquirt, which offers Bluetooth transmission of all engine parameters to a tablet display. But that's a bit of overkill for one data point...

That first link above looks promising (yet spendy):

"The "T&D Thermo" app (for Android, iOS) allows you to carry out operations such as making settings, downloading recorded data, viewing graphs, creating reports and sharing data via smartphones and tablets."

I will offer that the Bluetooth idea has merit, in that once you fully tune your car to run within acceptable parameters, there's really no strong pressing reason to have it in view at all times unless you change something. Maybe just fire up the app occasionally to check for deviations (which, if bad enough, you should have already noticed in the drive quality).
