A. Software handbook CHAPTER 1 LANDIRENZO OMEGAS SOFTWARE The LANDIRENZO OMEGAS program allows distributors' technicians in the Landi Renzo network to work on the LANDIRENZO OMEGAS injection control box. In particular, it is possible to program gas control boxes with data from the auto file, to see and modify several parameters acted upon by the control box. The program can be used without special knowledge of the functioning of a Personal Computer except, of course, the basics of the Windows interface. The LANDIRENZO OMEGAS program requires one of the following operating systems: Windows 98 SE, Windows ME, Windows 2000 and Windows XP. [. . . ] When Tinj benz assumes a value higher than that shown in fig. 10 point 1, the coefficient of K used to calculate the related Tinj gas is no longer that of the main map but as in point 2. These values of Tinj e K can be modified when calibrating the vehicle. At present this function is not used, but the open loop can be managed with the main map. Software handbook LANDI RENZO S. p. A. 17 Fig. 11 With the modification "CELL CENTRES, MAP OF K COEFFICIENTS" it is possible to modify the cell centres of: - RPM (from 0 to 8000) - Tinj petrol (from 0 to 40 mS) 18 LANDI RENZO S. p. A. Software handbook 1 2 Fig. 12 The gas injector downtime and petrol downtime are two parameters characteristic of the respective injectors and serve to compensate for the transitions from open to closed of the injector itself. 12, if they are relative to main injected (point 1) or extra injected (point 2). Software handbook LANDI RENZO S. p. A. 19 3 1 2 Fig. 13 CALIBRATION PROCEDURE The objective here is to ensure that the petrol does not modify the Tinj in the changeover from petrol to gas, and to this end the stages to be followed to obtain the best carburation are these: - click on start calibration 1 (management of the commutator takes place automatically by pressing key 2); - set a precise point of vehicle functioning characterised by an exact cell in the map above (e. g. 1000 RPM, Tinj petrol 4. 5 mS); - allow the injection time to stabilise then click on key 2; the vehicle will change over to gas; - by observing bar 3, evaluate how far in percentage terms the petrol injection time differs during functioning with gas compared with the petrol injection time when functioning with petrol; - if the space bar assumes high percentage values it means that the petrol control box is increasing the injection time while functioning with gas, or the vehicle on gas is lean and it is therefore necessary to increase the K coefficient of the cell in question; if the space bar assumes low percentage values it means that the petrol control box is reducing the injection time while functioning with gas, or the vehicle on gas is rich and it is therefore necessary to reduce the K coefficient of the cell in question. Variations of 2% are acceptable in the changeover from petrol to gas. 20 LANDI RENZO S. p. A. Software handbook Fig. 14 NB. : while functioning with petrol or gas, the percentage bar (point 3) loses all significance. If it is attempted to exit from the calibration without this being completed, the system advises of the need to close the procedure before it is possible to continue. Software handbook LANDI RENZO S. p. A. 21 3. 1. 7 Injectors 1 2 3 4 5 Fig. 15 This page shows some of the characteristics of the injector and its drive. 1 ­ 12V CURRENT MAXIMUM TIME (Tmax) This is the time 12V are supplied to the injector. 2 ­ MAINTENANCE CURRENT (Cm) This is the current supplied to the injector during the maintenance stage. 3 ­ INJECTOR IMPEDANCE This is the resistance of the injector. 4 ­ GAS INJECTOR MINIMUM OPENING TIME If the calculation of Tinj gas provides a value which is less than this minimum time, the system activates the value set as the minimum time. . 5 ­ EXTRAINJECTED GAS MINIMUM OPENING TIME As point 4 relating to extrainjection. 22 LANDI RENZO S. p.

There follows a brief description of the information visualised: 1 ­ STATUS VISUALISER: This shows, from left to right: A - Lock; B - Cutoff; C - Gas; D - Petrol. The active status is highlighted by a red led, the inactive status by a green led. 3 ­ INJECTION TIME A - Gas Injection time on gas actuated by gas injectors. B - Petrol Petrol injection time read from the LANDIRENZO OMEGAS control box via the injector disconnection wiring. Software handbook LANDI RENZO S. p. A. 23 4 - WATER TEMPERATURE, GAS TEMPERATURE, GAS INJECTOR VOLTAGE A ­ Water temperature Provides indications of the water temperature read from the sensor fitted to the "T" inserted into the engine cooling water circuit at the reduction unit inlet. B ­ Gas temperature Provides indications of the gas temperature read from the sensor fitted to the injector rail. [. . . ] Each METHANRE or LPG archive is structured with an archive in the left part of the screen and organised as a hierarchical tree diagram on three levels. This means that to arrive at a particular vehicle model it is necessary to move around the tree, each time selecting the correct branch from those available. The first level corresponds to the type of fuel in use and is managed automatically by the software once the type of fuel is set in the page F1 CHANGE TO GAS in F1 VEHICLE CONFIGURATION. The second level corresponds to the names of the vehicle manufacturers, arranged in alphabetical order, so the branch corresponding to the manufacturer in question must be "expanded" (keys RIGHT ARROW or RETURN.
