Those are the most important things right now to learn in my opinion. Can anyone answer why it was seeing such low timing? At one point I saw 0.5 degrees. I can tell you exactly how it saw it and it was all in the tune. My challenge to you guys is to figure out why (please don't randomly guess) and post your findings up. Include what tables were causing it, or even add pictures. This is important info that helps make me a great tuner compared to some but I'd be doing an injustice by keeping info like this. Look at the logs, find a spot where it shows around 1deg of spark timing and post a picture of that spot, and then post what it was that caused it. I will let you know if you are right or not. If you guys struggle too much will eventually just post it so we don't have people blowing a motor.
