Alpha N fueling algorithm

Post by DerekJ »

Hi All,

In the manual, when using Alpha N on V3 code, the fueling algorithm is shown as :-
PW = Req_Fuel * tps * VE(tps,rpm)
Is the TPS factor the raw throttle position value or is it the calculated output from the TPS-MAP table? I can see that the VE(tps,rpm) uses the calculated tps value.


Thanks
