    What am I doing wrong?

    I'm trying to tune the MAF with a wideband, but after I make changes to the MAF table the truck runs way lean. Here is the scan. Don't you take the number in the histogram and multiply it by the MAF tune table cell by cell? When I do that the truck become way lean like 1.40-1.20 Lmbda

    Paste special / Multiply by %. You don't have to do each cell one at a time. You can highlight the whole table and do the copy past.

    But I did the same thing. Just slower, and it jacked my AFR up.
