15 Pag. 15 “NEW STRATEGY” ADVANTAGES - CLEAR MEANING, IN FISICAL TERMS, OF PARAMETER - DRASTIC REDUCTION IN CALIBRATION PARAMETER - ALGORITHM FROM GASOLINE INJECTION TIME TO GAS INJECTION TIME COMPLETELY FISICAL AND MATHEMATICS MODEL BASED

16 Pag. 16 MORE ACCURACY NEW ALGORITHM BASED on a ENGINE PHISIC MODEL and DYNAMICS of FUEL and GAS LSI-PLUS VS OMEGAS

17 Pag. 17 FAST EXECUTION You drive the car on the road following a step by step procedure LSI-PLUS VS OMEGAS

20 Pag. 20 VERIFY FIRMWARE IS “AM202033G24” (4 CYLINDERS ENGINES) OR “AM202033G23” (3 CYLINDERS ENGINES) (IF IT IS NOT SO IT IS NECESSARY TO PROGRAM ECU AGAIN - F8 ECU PROGRAMMING)

21 Pag. 21 ECU PROGRAMMING Downloading AM202033G24-3

22 Pag. 22 ECU PROGRAMMING

23 Pag. 23 ECU PROGRAMMING

24 Pag. 24 CONNECTION TO THE LSI-PLUS ECU

25 Pag. 25 CONNECTION TO THE LSI-PLUS ECU

26 Pag. 26 DOWNLOAD DEFAULT FILE CONFIGURATION Download the default file with the same name AM202033G24-3

27 Pag. 27 RESET ERRORS AFTER DOWNLOAD

28 Pag. 28 DIAGNOSIS PAGE AFTER RESET

29 Pag. 29 ENGINE DATA SETTING

30 Pag. 30 ENGINE DATA SETTING

31 Pag. 31 MAP SENSOR CONFIGURATION SLOPE (mBar) (Volt)

32 Pag. 32 FOR A GOOD AUTOMATIC CALIBRATION: - ENGINE SHOULD BE HOT BEFORE STARTING THE PROCEDURE - NO EXTERNAL LOAD FUNCTIONING DURING AUTOMATIC CALIBRATION (FOR EXAMPLE AIR CONDITIONING) - DRIVE SO THAT YOU CAN REACH AS MUCH STEADY CONDITIONS AS POSSIBLE IN THE WHOLE RPM RANGE MAP SENSOR CONFIGURATION

33 Pag. 33 AUTOMATIC CALIBRATION PUSH F10 BOTTON

34 Pag. 34 AUTOMATIC CALIBRATION GRAPHIC INTERFACE

35 Pag. 35 GASOLINE ACQUISITION

36 Pag. 36 AFTER ABOUT 3 MINUTES AND AT LEAST N° 6 ZONE CHECKED, GASOLINE ACQUISITION IS OVER ZONES CHECKED

37 Pag. 37 GAS CORRECTION FINISHED NEW A AND B PARAMETERS AT LEAST N° 3 ZONES CHECKED, GAS CORRECTION IS OVER

38 Pag. 38 IDLE ACQUISITION MISSES POSSIBLE ERROR MESSAGES

39 Pag. 39 NOT ENOUGH VISITED ZONES POSSIBLE ERROR MESSAGES

40 Pag. 40 CORRECTOR “ CRUISE” WORKS ON “ A” CORRECTOR “ IDLE” WORK ON “ B” VALUE’S RANGE A : FROM 1 TO 6 B : FROM 0 TO 1,2 CORRECTORS: CRUISE & IDLE

41 Pag. 41 SET THE “OPEN LOOP” CORRECTOR TO ADJUST THE MIXTURE IN MAXIMUM POWER ZONE SET THE FOLLOWING VALUE TO SELECT WHERE THE STRATEGY IS ACTIVE Open-Loop RPM e Open-Loop Tinjb OPEN LOOP CORRECTOR

42 Pag. 42 GRAFICAL RAPPRESENTATION OF “IDLE”,”CRUISE” AND “OPEN LOOP” IDLE (B) CRUISE (A) OPEN LOOP

43 Pag. 43 NEW A AND B PARAMETERS A & B FACTORS AFTER AUTOMATIC CALIBRATION

44 Pag. 44 CORRECTORS UTILIZATION (IF IT IS NECESSARY) CORRECTION PROCEDURE IF “Tinj Benz” IN PETROL MODE > “Tinj Benz” IN GAS MODE: SET THE CORRECTOR AT A NEGATIVE VALUE( LEAN THE MIXTURE, IT’S TOO RICH) IF “Tinj Benz” IN PETROL MODE < “Tinj Benz” IN GAS MODE: SET THE CORRECTOR AT A POSITIVE VALUE( ENRICH THE MIXTURE, IT’S TOO LEAN) REPEAT THE PROCEDURE TILL OBTAIN THE SAME Tinj Benz AFTER SWITCHING FROM PETROL MODE TO GAS MODE

45 Pag. 45 CORRECTORS UTILIZATION (IF IT IS NECESSARY) THEY ARE EXPRESSED IN PERCENTAGE VALUES (POSITIVE/NEGATIVE). THE FIRST ONE MODIFIES CARBURATION AT MIDDLE/HIGH LOADS. THE SECOND ONE INFLUENCES CARBURATION AT IDLE/LOW LOADS.

46 Pag. 46 CORRECTORS UTILIZATION (IF IT IS NECESSARY) CRUISE CORRECTOR MODIFIES “A“ PARAMETER. IDLE CORRECTOR MODIFIES “B” PARAMETER. ENABLE FAST SWITCH TO COMPARE T PINJ ON GAS AND CHOOSE THE BEST CORRECTION VALUE.

47 Pag. 47 CORRECTORS UTILIZATION (IF IT IS NECESSARY) ONLY OVER THESE THRESHOLDS THE OPEN- LOOP CORRECTOR IS ACTIVE. IT IS AN “AND” CONDITION. IN THIS CASE IT IS NOT ACTIVE. IT IS EXPRESSED IN PERCENTAGE VALUES (POSITIVE/NEGATIVE). IT MODIFIES CARBURATION ONLY IN OPEN-LOOP CONDITION. IT DOES NOT MODIFY “A” – “B” PARAMETERS.

48 Pag. 48 K MAP CORRECTION

49 Pag. 49 IN CASE YOU KNOW A-B PARAMETERS IT IS POSSIBLE TO PUT THAT IN MANUAL MODE. AUTOMATIC CALIBRATION IS ALREADY OVER

50 Pag. 50 WARNINGS ABOUT AUTOMATIC CALIBRATION PROCEDURE - you are advised to use, if it is possible, an external MAP Sensor anyway; -it is not possible to make automatic calibration on Valvetronic engines (for example BMW engines) at the moment; in this case please use LR firmware version with K-map values; - it is possible to make automatic calibration on turbo engines even if working points acquisition could be slow enough in some cases; - once you finished automatic calibration procedure by an external MAP sensor you can take off that; at this point it is necessary to set MAP sensor as “not present” on F4-MAP-Twater page of LES-PLUS software in order to avoid wrong switches-back to petrol because of low gas pressure; - automatic calibration reset does not work if vehicle is running on gas or with switch indicator flashing; it is necessary to change over to petrol.

51 Pag. 51 OTHER SOFTWARE STRATEGIES LES-PLUS ECU

52 Pag. 52 INJECTORS PARAMETERS Put 0 in case you need eliminate extra-injection

53 Pag. 53 INJECTORS PARAMETERS GAS INJECTORS OPENING MAXIMUM DELAY WITH RESPECT TO OPENING PETROL INJECTORS.

54 Pag. 54 INTAKE VALVE AIR INTAKE WALL PETROL INJECTOR FUEL MASS 100 X X 100 = FUEL INJECTED X = FUEL ATTACCHED TO AIR INTAKE WALL 100-X = EFFECTIVE FUEL ARRIVED IN THE COMBUSTION CHAMBER WALL WETTING PHENOMENON

55 Pag. 55 THEARETICAL GASOLINE MASS REAL GASOLINE MASS ADDITIONAL FUEL MASS FOR PHENOMENON COMPENSATION THEORETICAL GASOLINE MASS DURING TRANSIENT

56 Pag. 56 SETTING THE TINJ FILTER WITH VALUES LOWER THAN 128, ESPECIALLY WITH CNG APPLICATIONS WE ELIMINATE THE EFFECT CAUSED BY THIS PHENOMENON GASES, FOR THEIR OWN FISICAL CHARACTERISTIC ARE NOT AFFECTED BY THIS PROBLEM, SO A HIGHER INJECTION TIME MEANS A RICHER MIXTURE DURING TRANSIENT PHASE. WALL WETTING SRATEGY OPERATION

57 Pag. 57 WALL WETTING STRATEGY Enrichment/Leaning in acceleration and/or deceleration ON Zone 1 Zone 2 ON

58 Pag. 58 CUT-OFF EXIT STRATEGY STRATEGY IS ON UNDER THIS LIMIT

60 Pag. 60 GAS PRESSURE PRESSURE LIMITATION STRATEGY ANALISYS

61 Pag. 61 GAS ENRICHMENT STRATEGY STRATEGY IS ACTIVE UNDER THIS RPM LIMIT % OF ENRICHMENT DURING STRATEGY STRATEGY IS ON IF RPM VARIATION IS HIGHER THAN THE VALUE SET NUMBER OF ENGINE CYCLES USED TO MEASURE RPM VARIATION
