Does anyone know if ECU uses data from MAP or not to start the engine (cold start)?

My engine starts very well on LPG system, OBD long corrections are near zero. But on gas petrol it starts hard. I haven't looked with wideband sensor yet, maybe not proper injectors.

OBD long corrections are +7% when engine works on gas petrol, so Bosch 0280155784 injectors are a little bit small for my engine. Bad.
