I'm a tuning noob. .... but where the hell is the idle deceleration fuel enrichment tab? Do I alter this in the fuel map instead? My car runs super lean in gear when I let off the throttle. Every setting I play with has no effect. Am I doing something wrong, am I missing something? Help me out please. Should not be this hard.

There is no idle fuel enrichment table in Nissan ECUs. It will read from the fuel map

If you let off the throttle and it is running too lean you can increase your minimum TP (TTPmin)

Isint this normal, and part of the Decel Fuel Cut function? I believe its supposed to cut fuel while in gear, and decelerating.

The fuel cut/recovery tables will limit injection between a certain RPM range (based on coolant temp). However this is for a short transitional time (in a narrow RPM window) so it isnt enrichment as such but a mechanism to prevent fueling on decel
