driftkids Posted October 9, 2013 Report Share Posted October 9, 2013 i wonder, when i only have a crankshaft position sensor, the engine knows only when it has done one revolution, that means it also injects fuel at the blow-suck time og engine? why im asking is if i connect a camshaftsensor, will it automaticly use 50% less fuel? and if my teory are right, a v44 with wasted spark and only crank sensor would use 4 times as much fuel as a v88 with crank and cam at same hp ? reason im asking is not the fuel consumptionproblem, but I am running e85, and dont want any more fuel than necessary to be injected in the cylinders because the too much e85 washes away the oil film, right?

Simon Posted October 11, 2013 Report Share Posted October 11, 2013 You might get some improvement but it not a case of twice or 4 times the fuel. In group fire mode the injectors still only fire once per 720 cycle but for some cylinders it has to wait to get in to the engine when the valve next opens.
