Once up to speed, I've gained up to 7degrees timing compared to summer logs. Since the weather has been getting colder gradually, I could test various IAT's and adjusted TANS axis accordingly. I will post screenshots of maps once I'm near my laptop.
Very useful maps indeed for those that live in changing climate
Keep in mind that more timing is not necessarily more power given the same quantity of air/fuel. The colder charge gives you better knock threshold. This explains why you frequently see OEMs give a little knock protection at the top but no added timing at the bottom. You really need to get the car on a really cold dyno to find the MBT torque and make sure you are not going beyond that. With your 7 degrees more there is a good chance that you're just putting more stress on the bearings and making less torque.
