Min.Dif. MAP to enable AE at Idle?
Can anyone explain this function to me and what changing this value would do? What is the variable its refering to? The stock setting is 1.3 KPA. what would happen if this value was raised or lowered?

Just by the name, most likely it is to prevent spurious MAP AE during idle. At idle the fluctuating MAP can cause AE to become active. Which is not always desired. If and when the MAP does make enough of a change above the value (1.3 KPa) then AE will activate.

Thanks, Sometimes the obvious can sometimes seem just too easy as you pointed out.
