Just got this brand new jewel and ran into a problem with the K-tech instructions. While doing the RC Learn process the last item in the menu is "APP THRO ENABLE".

It's surprising to me that these brand new instructions don't reference this item. Can somebody tell me what it is and where it should be set?

And while I’m on the subject of instructions: the manual directs us to put the fuel filter with the o-ring towards the pump which is opposite to the flow arrow on the filter! I think I’ll go the the flow arrow!

So I googled it and found an RCU post that informed us that it enables a smart phone app to run the engine without a transmitter. That would be pretty cool.

Yeap! That’s all it is.
