      Eric,

      Before you start digging around, swap the water sensors and leads to the gauges to see if the problem moves with the swap. Make note of the path the leads take to the gauge.  Next, swap gauges between karts.

      Thanks Tony.  On the list of things to do.

      And here’s a screenshot showing the temp.  Red is one engine and yellow is the other engine with the temp issue.  Its also dangerously close to too hot – 186 degrees.

      I agree with Tony, first step is to change the sensor and lead. Secondly, make sure that the RPM wire and the water temp lead are not wound around one another or zip tied together. I have seen this happen before and it seems to be a result of the frequency. Sometimes it works fine, sometimes it is mind boggling. Since it changes with RPM, I will bet that is your problem.

      Thanks,

      MM
