I can't seen to find any advise against AutoTuning at Idle .

As long as you don't have a radical cam it shouldn't be a problem .

The VE table in use is updated as you drive. It is updated in RAM memory, which is lost if you power off, so if you want to keep the changes, you have to 'burn' the VE table to flash memory to make it 'stick'.

That is what I thought it did. However, I still have one sticking point. When you hit the burn button, occaisonally it says tuning point outside of window or tuning point not near vertex. Suppose I have been driving with auto tune on for fifteen minutes when I hit the button; surely it would have made some changes to the VE table in ram. So why does it give these errors just because at that particular moment I'm not inside the window, there must be some changes made while I was driving that were inside the window. Why wouldn't it go ahead and burn those changes?

The chengaes are made in the ram memory. The message you got about not being near vertex and all these other messages on the same place does not affect that.

So say you drive the car for 10 minutes with autotune on. It tunes fine for 7 minutes, then sometime within the last 3 minutes you get a "not near vertex" or "out of window" error... if you hit "burn" do the previous 7 minutes changes still get burned?
