the load on on 16v (due to no map sensor)
is based on MAF readings.
it sees maf low , at idle and computes that + rpm to learn load.
the car (ecu) is designed to be naturally rich running ( not to burn up valves)
and the o2 sees the error and the ecu removes fuel to get closed loop burn.
-7 means it removed that much fuel to get closed loop.
not sure why, it goes (LTFT) to +5%,unless FPR is bad.
