2.11. Petrol portion map

The "Petrol portion" tab offers configuration of the petrol post-injection with simultaneous gas
injector control. Configuration of petrol post-injection is made on a two-dimensional map with an RPM
and petrol injection time axes. Like on the RPM correction map, the cursor shows the engine operation
curve point. Navigation on the petrol portion map is identical as on the RPM correction map, i.e. cursor
keys (← ,↑,→, ↓), SHIFT and CTRL keys can be used to select map areas and modify their values.
Map values specify the percentage of petrol while running on gas in a given operating curve point. The
actual petrol post-injection time is based on the map values related to the petrol injection time in a
given operating curve point. Example: 20% for the 10ms column means 2ms petrol extra-injection.
After modification of the petrol portion map, verify if the mixture is correct in areas
allowing petrol extra-injection.
