Renix can be tricky at times, but when they're sorted, they are fantastic.
These Renix engine monitors (standard model here: https://nickintimedesign.com/product/renix-engine-monitor-ii/ or clock panel replacement version here: https://nickintimedesign.com/product/rem-clock-panel-v4/) give a readout of what your Renix system is doing in real time. It's almost like an OBDII scanner for newer vehicles, if you are familiar with those. Otherwise, feel free to drop your questions in the Modifications and Repairs subforum and people will be along to help out.
