question on MBC

[fernando]

was thinking of getting a manual boost controler, but the boost on our cars is computer controled, would the computer recognize the extra boost and compensate fuel.....and also the n75 valve acts as something like a boost controler would a MBC replave the n75?



thank you

since you have an 01 search "diode"

i am already chipped, wouldnt the diode interfere with the chip?
and from what i have gathered about the diode it just stops the computer to limit boost

Ecu uses the maf sesnsor to tell it how much air is being sucked in by the turbo, if you turn up the boost the maf readings go up and the ecu adds more fuel. The 2001+ also has a wide band 02 which the Ecu uses to hit a target air/fuel ratio.
