    Fuel Managing Unite to tune a car.

    Dear all,
    I want to know about FMU whether it helps me to achieve good results on tuning of my SC car. Does it helps to retard or advance my ignition timing?
    Which unit you prefer to tune engine FMU or some Piggy Back or stand alone?

    I think the same but I want to know benefits and disadvantages of FMU in comparing with ECU tuning or Stanalone.

    Benefit- Cheap

    Disadvantages- Inaccurate fueling, no timing control.

    Get a real tune, weather it be by stock DME or a standalone. FMU's and piggybacks are obsolete at this point.

    With FMU I agree, but why piggyback is bad?
