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
fupsrl - Faktor umrechnung "ps"/"rl"
rlsol/pssol (factor for calculating pressure from relative charge in % per hPa)
lde - LadeDruckError
plsol-plist (boost deviation - feedback input to the LDRPID)
LDR - LadeDruckRegelung
Boost pressure regulation
ldtv - LadeDruckTastverhältnis
Wastegate duty cycle
Md
misfire detection?
nmot
Engine speed (RPM)
NWS - KnockWelleSteuerung
Cam shaft control
RLFS - Relativ LuftFüllung Steuerung?
Relative air charge control?
rlsol
Requested load (which is capped by engine load corrected specified)
rk - Relativ Kraftstoffmasse
Relative fuel mass
plg - Pressure Ladedruck Grund
reference pressure for vpssplg ratio
plist
actual boost pressure upstream of throttle plate
plsol
pssol/vpsspls (requested boost pressure upstream of throttle plate). When vpsspls is lower (e.g. during "dynamic driving"), plsol will be higher (overboost). When vpsspls is higher (e.g. during "steady driving"), plsol will be lower (no overboost).
pssol
rlsol/fupsrl (requested intake manifold pressure downstream of throttle plate)
pu - Umgebungsdruck
Ambient pressure
Tans - Temperatur ansaugluft
Intake air temperature
Tmot - Temperatur motor
Motor (coolant) temperature
TV - Tastverhältnis
Duty cycle
te - Einspritzzeit/dauerung effektiv
Effective injector on time
ti - Einspritzzeit/dauerung
Injector on time (actual)
Verhältnis
ratio
vpssplg - Grundladedruckverhältnis
pssol/plg? (pressure ratio between intake manifold downstream of throttle plate and reference pressure?)
vpsspls
pssol/plsol (pressure ratio across throttle plate)
vpsspu
pssol/pu (ratio of requested intake air pressure downstream of throttle plate to ambient air pressure)
