Summary of change:
== BiFeul (LPG + petrol) and VEMS == most relevant functions are: * [http://vems.hu/vt/help/v3/v3_config_switch.html config/table switching help] (and referred tutorial) ** eg 2 injection and ignition maps (one for petrol, one for LPG), totally independent, also 2 different configurations * LPGandBiFuel/Switching * [http://vems.hu/vt/help/v3/v3_anytrim_control.html anytrim] * It has MAP sensor on inlet, it also has pressure sensor on LPG rail. LPG pressure => '''anytrim''' can be used to compensate fuel pulsewidth, and possible change ignadv. ---- * 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). >>> '''Switching will be done on fuel cut time'''
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
