Looking over a Ford bin, it seems to me that Ford has based their programming purely on lambda (AFR) readings. Unlike the GM where we can 'EASILY' control the settings, such as our PE curves and spark, Ford has worked things in a completely backwards way...if your a mathematician i'm sure it would help. Unluckily for me I passed with a C in stats and maths :/ Any other ideas regarding tuning the Ford bins???
Another question, is there any reason why this parameter only shows up to 5000rpm? Seems kinda low to me, on the Trailblazer bins it shows up to around 7000rpm
