Yea I've been using that method as well, at least the maf scaling function in romraider that does all the work for me haha. I was more interested in the 2.5v and higher. Anything easier than logging and just doing trial and error? I was thinking along the lines of maybe making fueling static at a safe value like say 11 afr across the whole table. forcing open loop 24/7 to avoid learning being an issue, and then any values in my logs that aren't 11 could be attributed to maf scaling. I haven't tried it yet because im a little uncertain. does that sound like a good idea?

closed loop -- romraider has pretty decent tools already built in. I believe these are based largely on willaty's methods.

open loop, load WOT runs into airboy along with the correct fuel map. Then copy to Bad Noodle's MAF spreadsheet.

Ahh yea I forgot about those spreadsheets. Do you think my method would work though?
