Seems like you may be confused on what 'idle advance' does..its not supposed to change your timing as load increases. It merely just fixates to a specific degree of timing while only in idle..when you give it gas you timing will switch back to the set timing in your spark table. So idle advance deactivates when you press the throttle

That is basically what I thought it did, but when you enable the setting, you get a 'curve' to define. So, I have mine set so that as load increases while idling, the timing jumps up a bit to steady the idle. I agree this may not be the best thing to do, I'm just going off of diyautotune's suggestion of creating a spark map the increases just a bit along the far left side of the table to help steady the idle. It was my assumption that 'idle advance' was a special function that extended the functionality of simply setting up your table like diyautotune suggests (linked a few posts up).

Do you have any suggestions on what the spark table should look like at idle? 20 deg, 30 deg?

Mine is doing okay, but stumbles a bit once in a while. I'm still on 'open loop always on', so maybe I just need to spend some time with the closed loop settings.
