You need a wideband as well.
Do you have one?
There is demo on ecmlink page to set the idle and cruise this is good info but I had to read it about 10 times to work out what was being said.
Thats as far as I got. Good idle and cruise and no knock and fat fuel on load and stock boost...its safe and slow till we going again.
But my understanding is once you have the cruise and idle set. You keep pulling timing till you get knock and then back it off a touch (petrol not for e85) then lean the fuel off till you get to your selected afr. Then add some boost and retune the top end.
In a nutshell. ..
