This is all with the throttle connection not even plugged in the RX. Before I was able to change the settings like glow power & max RPM wihout RX connection. We use mainly 36mHz here btw.
After I cycle the ECU it goes back to the normal screen when you receive data , eg the rpm, egt, pump voltage etc. and it does read this data like normal. until I press a button again and the thing jumps to the "IR Remote Terminal from Simjet Denmark etc" screen and stops reading. I measured every wire in the cable separate (from plug to plug) for faulty connections, can't find anything faulty.
