Map Editing

The TuneEdit_Marelli program allows you to adjust fuel and ignition tables for the Marelli map files.
You can adjust the fuel tables for front and rear cylinders and ignition tables for front and rear. You can also adjust the rev limit, speedo and can change the dash message that appears at start-up.
On some 5AM ECU maps we have also found the thermo fan setting so you can adjust the fan turn on point.
As new tables are identified we will add access to these in the TuneEdit program.
The following screen shot shows the TuneEdit_Marelli program.
 

 
The fuel and ignition maps can be viewed as text as shown in the screen shot above, or they can be viewed in a graphical view
The screen shot below shows the fuel map in the graphical view.
 

 
When you process the log files the TuneEdit program will build a table containing the average air fuel ratio for each of the map points you passed through during the logging session.
The screen shot below shows the TuneEdit_Marelli screen with the data from a logging session.

The values in the A/F tables are used to correct the fuel tables. These corrections are done by the TuneEdit_Marelli program when you select the Correct fuel map option.
