I have a program that can read that data through the obd port but that was being used by the tuner and I am not sure if it is available to him while he is tuning. I assume the ignition advance is. As far as the a/f ratio is concerned the tuned version starts out at 13.5 (3500) and goes gradually down to 12.5 (5000) and stays there right up to 7500. The stock a/f started out at 12.5 and goes below 12 at 5000 and gradually down to 11 at 7300. The graph is posted somewhere in this forum.
