Hi Crazy-Mart,Crazy-Mart said:the throttle setting in the SAFC2 is mainly used on turbo car... at wich past a certain TB opening get the turbo to spool up... this option is great for N/a ecu that needs tuning in the boost range/WOT... will mainly keep the cruising on the low TB opening map and when boost hit hard (50% and more tb opening/wtv setting you put in there) it hits the HI-Tb map.
i saw Spec-Vs with SAFC2 tuned on a wideband gaining around 7-10 hp on the 2002-2003 b15... the program is relatively lean for the engine sacrifying some hi-end power...if you dont want to spend that much on the SAFC and get those lost HP, Nissan dealer can retune the ECU for a better timing set with they're scanning tool. It seems that the car feels more nervous with some timing advance.
