I was messing with mine I maxed out all the settings in the advance screen…I also had a loose wire on the temp sensor…e08 started to pop up before it would start the loose wire was the problem… After that it would pop up when it got hot I maxed out the fan rpms ran fine after that…e10 started to pop up maxed the fuel pump setting… that seamed to stop that…I also set the glow plug to it lowest setting…if you just max them out all the way to the highest settings and lowest settings the unit will change it to the max it is capable of doing… might help if you still struggling with it…
