Anyone know what the maximum advance the ECM can crank into the system?? Is that in the ECM tables somewhere? If we start with 10 degrees, and add 'normal' advance values, and the EGR adds another 9.5.....................

'60's Mopars will tolerate about 40 total, and I assume that's typical. But since the EGR only activates under relatively light loads, did GM design it to push the envelope, and run much higher advance settings under those conditions?? Maybe 50 degrees? If the EGR is disconnected, are we running only about 30 total advance? Can the computer be fooled so you can just measure total advance with a light like you can with a conventional engine? Gotta try it, I guess.

Was wondering that myself, anyone have an answer on this?
