Finally the actual duration of the control pulse ti is calculated, considering pick-up delays
of the injectors, fuel cutoff (e.g. overrun cutoff, speed limiter, gear cut) and cylinder indi-
vidual correction factors. Please refer also to the system overview in the Function Descrip-
tion ECOV.

Mixture correction, set to 1.0 for startup
Global factor for mixture correction, set to 1.0 for the be-
gin of startup
If a correction by fuel pressure is intended, set = 1. In this
case please set PRAILREF according to the referenced fuel
pressure. Also refer to MP_P22MOD. Usually the pre-
defined values are suitable. If unsure, set CWPRAILCOR to
0 for first startup.
Correction via engine coolant temperature. Usually the
predefined values are suitable. Ensure, that for coolant
temperatures driven on your dyno during calibration, no
warm up factor applies (i.e. FINJ_WARMUP is 0.0 for this
temperature).
Desired Lambda value, valid for map position 1. According
to your expectations, e.g. 0.9. For alternative positions of
your map switch the maps MP_LAM_MP2 (3) or (_PACE)
apply, therefore ensure correct switch position
Decision between alpha/n or p/n related load calculation
Decision between P1 and ambient pressure
Correction via intake air pressure
Correction via ambient temperature
Usually the predefined values are suitable. If unsure, set
FRLTINT to 1.0 for first startup.
Relative load depending on throttle angle and engine
speed. Set value until your desired Lambda is matched.
Correction via intake air pressure
Correction via ambient temperature. Usually the pre-
defined values are suitable. If unsure, set FRLPTINT to 1.0
for first startup.
Factor to throttle dependence. If unsure, set to 1.0 for star-
tup.
Relative load depending on throttle position 1-4
