Piar Posted January 21, 2014 Report Share Posted January 21, 2014 Hi everyone! Do Anyone ever mind how Vipec calculate how much fuel to inject? As I can see and estimate calculation pretty simple and shitty. Because vipec isn't calculate how much air have been consumpted! And then take a look at AFR Target table/fuel table/latency/other corrections to calculate injector pulsewidth. We just operating some kind of "numbers" in fuel table to take desired (afr table)result. Also as we can see in help file vipec do not reccomend to change afr for more than 0.5 afr due to fact we don't get desired afr. So all we do in fuel table - just try to get our AFRs by the changing pulsewidth which we see not in ms. That's why we often have very shitty 3D graphs. Also vipec don't take in account IAT to determine air density. Just simple IAT correction table which can just add/subtract percent from injector pulsewidth! NOT calculated air mass! Can Anyone explain to me how it's possible to have stable AFR each day in any place with such kind of calculator? Guys Can I ask you to create normal speed density strategy to calculate mass of air and just then injector pulsewidth? Quote Link to comment Share on other sites More sharing options...
