Thanks guys! Your course has really helped me out. I am currently automatically calculating the pulse width calculations based on data that I retrieved while logging.

I am going to work on filtering out data I don't care about. Do you have any suggestions on areas I may want to pay particular attention to adjusting/filtering of the data?

If you're calculating a correction factor, I'd recommend eliminating data with high rates of change of TPS which may be requesting or requiring accel enrichment. I'd also eliminate any data with very high ECT or IAT that could be as a result of heat soak.
