I'm trying figure out why timing advance is being pulled at a steady state, low RPM, steady throttle. It's inducing a down right irritating surge. It happens in between 1400 and 1800 rpm and .22 g/cy. About 15 - 18 deg is being pulled. It's like something is confusing the ecm. It's instantaneous. I have both hi and lo tables matched. It appears that the ecm is referencing the coast down table for a split second, or possibly adaptive idle???? I'm at a loss what to do at this point. I will gladly pay someone to help if needed, and I promise to keep your secret trick to myself, if that's important to you....
To save you time, you can see an example of this oddity at frames 26,452, 24,850, or 24,936.
The log was after I flashed all new timing tables I shamelessly stole from an LS7 tune that RWTD posted after I totally screwed up my tables. I have addressed the knock retard areas that are in the knock retard histogram. If you see anything else in the tune or log that would demonstrate idiocy, please feel free to inform me...LOL
The tune file is what was loaded during this log.
