The times of injection Grande Punto 1.3 mjet 90 cv

[andrea80]

Hi friends. . can you give me a hand to figure out how to change the timing of fuel injection, which ECM called "injection split" on this grande punto 90 hp ? I modified the pedal by removing the holes in the acceleration , but I noticed that if you do not touch the map of the times solve little on the low...I've done a bunch of tests but nothing. Attached file ori and confided in a your help...thanks to all !
