In general, all lowercase acronyms are calculated values; maps and other acronyms are typically all caps.

ASR - AntiSlipRegelung
Anti slip control
B_ldob - LadeDruck OverBoost
1 - overboost enable (dynamic driving, use KFVPDKSD), 0 - overboost disable (steady driving, use KFVPDKSE)
B_ldobsp
Post overboost lock-out bit (force overboost enable - ignore steady driving resumption)
DIA
Diagnosis
DK - DrosselKlappen
Throttle plate
DKW - DrossellKlappenWinkel
Throttle plate angle
DLR - DeltaLambdaRegelung
Delta lambda regulation
DMD - Delta Moment Dashpotende
 ?
DMD
Diagnose Misfire Detection
DV-E - ?
Wastegate
evtmod - EinspritzVentil Temperature (mod=Model?)
Estimated fuel injector temperature
FGR - FahrGeschwindigkeitsRegler
Cruise control
fkmsdk
Multiplicative correction quantity for determining pvdk (pressure upstream of throttle plate) from measured ambient air pressure (pvdkds)
fpvdk
pvdk/1013 hPa (correction factor for adjusting the air mass flow at standard pressure upstream from throttle valve to instantaneous conditions)
ftbr
 ???
ftvdk
Intake air temperature compensation factor for converting the standard air mass flow to an air mass flow at an instantaneous temperature
furl?
fupsrl - Faktor Umrechnungs von ps->rl
rlsol/pssol (conversion factor for converting the intake manifold pressure to a relative charge in % per hPa)
KLAF
Outflow characteristic for adjusting the standard flow measured at an above-critical rate of flow to below-critical rates of flow
KUMSRL
Parameter for determining the relative cylinder charge from the air mass flow, the engine speed, and the piston-swept volume
lde - LadeDruckError
pssol-ps or plsol-plist (boost deviation - feedback input to the LDRPID)
LDR - LadeDruckRegelung
Boost pressure regulation
ldtv - LadeDruckTastverhältnis
Wastegate duty cycle
LL - Leerlauf
Idle
Md
misfire detection?
nmot
Engine speed (RPM)
NWS - KnockWelleSteuerung
Cam shaft control
RLFS - Relativ LuftFüllung Steuerung?
Relative air charge control?
rlroh
Air mass flowing into the intake manifold, uncorrected relative charge of a cylinder
rlsol
Requested load (which is capped by engine load corrected specified)
rk - Relativ Kraftstoffmasse

pvdkds
Ambient pressure measured by a pressure sensor
pu - Umgebungsdruck
Ambient pressure
Tans - Temperatur ansaugluft
Intake air temperature
Tmot - Temperatur motor
