idle surging from timing glitch
been working on this pain in the ass idle surge. Its apparently caused by this timing glitch that drops to 1 to 2 degrees when I have all the maps intentionally set to 15 degrees to try and narrow down the problem. I even changed the high and low octane maps to 15 just to cover all bases. I even zero'd the over and under speed maps to zero and its still the same. any help would be really appreciated. gen 3 6.0 engine with manual set trans. not sure if its related but the engine also hits a wall at 3k rpm only in drive and bounces like its hitting a limiter of some sort.
here is a short log of what its doing along with my tune
