if i were to choose a simple and user friendly management i would go for e manage ultimate, a wide band sensor and the AF harness for the emanage to tune target AFR.
but in nayoe case... erm... the fc is quite high as its already equiavalent to my city driving of my 1jz. it consume about the same amount of fuel as you now. btw since u say you have a sard fpr. may i knw wats your pressure when you on your key (b4 starting the car)..get someone with a proper AFR to double check.you might be able to lower down your fuel pressure a little (if it is set too high) . or you can add a simple device such as the AFC 5 button or blue to do some minor fuel trimming..
just try to set low pressure on Sard FR, my engine goes crazy. some knocking sound due to lack of fuel.
some of friend said that AFC 5 button could not used with proton/mitsu AFS. i donno why. izzit?
