I'd appreciate peoples thoughts on an issue that popped into my mind yesterday. I've got a 20v conversion to start shortly. AGU with K04 and MBE (QPeng) engine management. I'm also going to LPG it when done as the vehicle does a lot of miles and I've found LPG to be quite a success. (for me anyway) The engine management system can obviously be mapped to suit any fuel octane rating> That got me wondering if I should get it mapped for the higher 97 RON as it would better suit the LPG afterwards or go with he lower octane fuel. Thoughts are most welcome. Oh yes while I remember do people know if an AFR guage would work with LPG? I've no idea what differences there are and how the LPG ecu fools (if at all) the engine management. ta
