I've been inactive tuning Nistune veihcles for couple years, and now i found that feature pack developed alot.
I found out that i dont need to touch K-const in order to resize injectors for example.
Is there kinda a qucik guideline for how to better tune in featurepack enfabled veichle compared to standart nistune
Do i have to resize maf? or it is done better way now in geaturepack endbled ECUs?

All our documentation has been updated to incorporate feature pack.

Yes adjusting TIM instead of K for injectors means that load is not affected. However changing MAF still affects load, so our preferred method is to adjust K constant after MAF upgrades so that the load cursor reaches the last column of the factory load scales still, and offset any K changes to injection with TIM

Adjustment of TIM done in closed loop (cruise at 2000rpm, light load)
