Sometimes the PCM is pulling timing on my car and I have no idea why. I am running Custom OS3 and I am running my car in OLSD. I have zeroed out all the tables that I can find that add or subtract timing. I have attached my tune and a log file. A good place to look at in my log is between frames 12920 and 13620. That is a perfect example of what I am talking about. I have been dealing with this for awhile and just can't figure it out. Any help would be greatly appreciated.
