Summary of change:
== BiFeul (LPG + petrol) and VEMS == 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 petrol, one for LPG), totally independent one from the other, or better yet, to have complete 2 different configurations: one for petrol, one for LPG... Is this possible? Will you upgrade to ATmega2561? :lol: Is there enough memory space? :D 4 outputs should be connected to petrol injectors and other 4 outputs to LPG injectors. It could be done with only 4 outputs, and one relay to change powering (+12V) and to petrol or LPG. But than I would have some delay in injection on fuel switching, but this must be done smoothly... Just like it is done now with LPG piggyback... So better option is 8 outputs (4 LPG, 4 petrol). As I sad I have big knowledge about LPG injection, and AVR, so I would be interested in joining development team...
