27. uretion of the vehicle in any case its right value should range from 2 5 ms at idle speed to 18 ms at maximum engine rpm If at idle speed the gas injection time is 2 5 ms but carburetion is still rich maybe Injector nozzles are too big Gas pressure is too high On the contrary if at maximum engine rom gas injection time is higher than 18 ms and carburetion is still poor maybe Injector nozzles are too small Gas pressure is too low 24 gt Software Manual AIS Rev 5 del 01 10 2013 Since the system can be installed on many vehicles with different injection time ranges you can adjust the carburetion map to the specific vehicle by changing map references To do that you just have to click on injection time column or rom row and modify the range as shown in the following picture 6 Arnona iy ton intere nae TRIM 1 500 1000 1500 2000 2500 3900 3500 4000 4500 5000 5500 AA CALIBRA DE D DEN Py 320 tunz Appikation status READY _ r _ rel System status CONNECTED Configuration prova gas Firmware 02 02 Resttw 02 In order to make calibration you can also use the following quick controls on the keyboard e C pressing C button from one field of the map you can select all the fields of that column R pressing R button from one field of the map you can select all the fields in that row e RC pressing R button and the
