This way the adaptation value for fuel tank ventilation (FTEA) at high absorption of the EVAP Canister could look like this:
Example:
Fuel tank ventilation:
FTEA: 0.93
Button 1 or N
Between the individual adaptation phases, which could be at intervals of 250 sec. or 650 sec. and which are dependent on the last applicable
correction factor, a purge phase for the EVAP Canister is programmed.
Should the corrections for the fuel/air mixture caused by the adaptation be so large that it reaches the adaptation threshold a fault will be recorded in
the ECM.
NOTE: Map changes at full load (FRA) react multiplicatively, map changes in the idle range (TRA) react additively.
