Calculator for tuning with narrow bands

I'm one of the guys tuning only with narrow bands. I calculated the %fuel error with this spreadsheet and then multiply the corresponding values in maf transfer function as needed(decipha taught me :)). I just thought this sheet makes that process a little easier. All you need to do is turn off adaptive so the kamfr stays at 1, then get a datalog with long steady pulls. Then input your lambse1 and lambse2 values in and it will calculate the rest for you. Hope those who need it find it useful. Its my little way of saying thanks for this board. *EDIT* I changed the file to a zip file for ease. Also, the .jpg version had a few lines in the 4.25 to 4.5v using a commanded value of .875 instead of 1 for commanded value. be sure to check the formulas in the calculation cell, or better yet, download this one. They are all lambse=1
