Motronic abbreviations

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 requested 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)
