I'm trying to finish programming my Mychron 3 Gold and have most of it working. (Thanks Jay for the advice on light settings.)

The temp though is reading in the mid 300*s. Oil pressure looks fine. RPMs are coming in fine but I'm pretty sure the temp is wrong. The manual doesn't say anything about the low scale, high scale, or parameters.

Anyone know what I'm doing wrong now?

You most likely have the wrong type of temp sensor selected.

Try the other options and see if on looks better.

Any chance you could look at what you have set in your race studio configuration Greg? [Smile]

I have it set on thermocouple. There are a few other choices. Temp VDO 40-120C maybe?

Does the sensor have a yellow 2 prong plug? If not it's not a thermocouple.

I'd guess PT100.

None of the settings made the readings change. I tried everything temp related from thermocouple to Suzuki Super Sport. The odd thing is, as the engine heats up, the temp readings drop from about 350 to 285.

My water temp gauge is using the calibration curve thermoresistance PT 100 ...and it works properly. Thanks, Jay

Turns out that you can get exactly what I was experiencing from a bad connection inside the unit itself. Wedged myself back upside down in the footwell, changed it to different channels, reprogrammed and both temp and pressure read properly.

Apparently, with this sort of bad connection, vibrations will cause the readings to go haywire. As the car warms up and the vibrations simmer down, so does the reading. 350F down to 285F corresponds pretty well with about 1200rpm on start up down to normal hot idle.

Thanks Jay and Greg!
