The gist is that you'll be logging a boatload of data, mostly because of how much you'll be discarding. You'll be manually filtering out based on
1. IAT's that are too high, indicating when you stopped at a stop light
2. rapid changes in MAF (v)
3. times when you accidentally went into open loop

among the other items that williaty suggested you filter by. you want a lot of data because you're also trying to test the validity of your maf curve across the entire range of closed loop.
