Let's expand things about LPG...
It has MAP sensor on inlet, it also has MAP sensor on LPG rail (because LPG pressure isn't constant, and therefor you need to implement this in injector opening algorithm). So, it's like fuel with this element added, and also, it must have a little more advanced ignition...
So VEMS must be able to have 2 MAP-injection and MAP-ignition maps (one for fuel, one for LPG), totally independent one from the other, or better yet, to have complete 2 different configurations: one for fuel, one for LPG...
Is this possible? Will you upgrade to ATmega2561? :lol: Is there enough memory space?
