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.
4.1.5 Main Data Labels to configure for Engine Start up
Main Data Labels to configure for engine start up
MP_MIXCORR(2) Mixture correction, set to 1.0 for startup
MIXCORR_APP Global factor for mixture correction, set to 1.0 for the be-
gin of startup
CWPRAILCOR 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.
FINJ_WARMUP 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).
MP_LAM_MP1 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
4.1.6 Main Data Labels for Load Calculation
Main Data Labels for Load Calculation
CWLOAD Decision between alpha/n or p/n related load calculation
CWLOADP1 Decision between P1 and ambient pressure
alpha/n system
FRLPAMB_P1 Correction via intake air pressure
FRLTINT Correction via ambient temperature
Usually the predefined values are suitable. If unsure, set
FRLTINT to 1.0 for first startup.
MP_RL Relative load depending on throttle angle and engine
speed. Set value until your desired Lambda is matched.
p/n systems
FRLPAMB_P1 Correction via intake air pressure
FRLPTINT Correction via ambient temperature. Usually the pre-
defined values are suitable. If unsure, set FRLPTINT to 1.0
for first startup.
FRLPTHR Factor to throttle dependence. If unsure, set to 1.0 for star-
tup.
MP_RLP1 … P4 Relative load depending on throttle position 1-4
