RPM and petrol injection time axes. Like on the RPM correction map, the cursor shows the engine operation curve point.

Petrol portion map

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.
