Hi everyone,

Just wondering if there is a way to connect and display coolant temp on a Rotax 912 install.

Kind regards,

Thank for the views,

Im going to try using OAT or CHT6

If you use our OAT sensor it should work. Hooking it to a different sensor would be tricky as the probe is a custom current-based output.

If you have an ungrounded J thermocouple you could use CHT5/6, I would recommend placing a jumper wire between - and + of the unused EGT/CHT inputs to keep them from floating. You will also probably need to turn off the low red warning zone.

Ya right. I also think it will work out. Lets try.
