I say B16A (P30/P08) chipped.
This way the chip can increase your rev cut which e-manage cannot do.
This include speed cut form standard ecu.
Fueling/timing all can be taken care by emanage.
what is the problem if RPM meter giving the wrong reading?
my car is suzuki vitara
sometimes when the car engine loud sound (means high rpm) but the rpm reading only 800
almost every time it gives the wrong...
