    When did Nistune come out with launch control feature?

    I'm planning to have it button activated when my new work Is getting M done

    I think NEM has used it

    I would have it clutch and/or handbrake switched.

    Flat shifting needs the clutch switch

    According to the Nistune site, those of us with Type2 boards can get a reflash upgrade.
    Wonder how much that would cost.

    If you ask Matt really nicely, and pay for return postage, afaik it is somewhere close to free.

    Was $160 with the flex harness for me. I use the launch control feature.

    So what is it like?
    Is it worth the upgrade for an NA?

    Not for N/A...

    Shortly it spit some petrol on exhaust stroke which then combust in exhaust manifold and that keeps turbine spinning while it rev limiting at desired point.

    As a outcome of petrol igniting in manifold... It trows flames out of exhaust...

    Turbos are not made to take that kind of punishment so they won't last long...

    Darn id love my NA to throw flames out of the exhaust just for sh**s and giggles

    If you like flames you can go with Nistune or cheaper option get (bee r rev limiter) which will do just that...

    Slightly incorrect

    Nistune is a fuel cut rev limit
    (Not really flames)

    BeeR is a ignition / spark

    Excess fuel dumping gives flames

    It's ignition cut that causes flames as the injectors still operate.
    This is guaranteed to melt your catalytic converters.

    Nistune Launch Control

    Fuel cut, & ignition timing retard functions triggered using either speed or clutch switch input.

    Launch control has been added to Nistune.
    In the current version it utilises Nissans fuel cut facility by adjusting the
    RPM limits until the desired trigger has been reached.

    Enable launch control in the Feature Control Flags panel.
    This will provide the ability to use the following Launch Control (LC) parameters in the ECU.

    Triggering

    There are two forms of triggering launch control
    1. Speed triggering
    Launch control is automatically activated from zero speed, and the limiters remain in place until the launch speed is reached.
    Adjust the speed to increase/decrease the point at which the engine can rev freely.
    2. External switch triggering
    This can be used independently or with the speed triggering.
    The existing power steering input line to the ECU will be used for the launch control triggering.
    To disable speed triggering, increase the launch speed to maximum value.

    Trigger Operation
    When launch control is triggered, the check engine light will continuously flash quickly until the termination condition is met.
    This can be disabled by unticking ?launch flash? in the feature control flag settings.

    Trigger switch operation will activate launch control when vehicle speed is at 0, engine speed is under 1200rpm and the switch has been pressed.
    Once activated, once the switch is pressed again over 1500rpm the launch control will be deactivated and the check engine light will cease to flash.
    Also if you wish to use trigger speed in addition, you can set this at a desired speed to deactivated launch control once the speed has been met.

    Note: Trigger switch will allow the user to operate launch control in vehicles without a speed sensor connected.

    Launch Control Parameters
    The launch rev limit will cut fuel at the specified engine speed.
    The cut performed will replace the vehicles soft RPM cut limit until launch control is deactivated.

    The launch ignition retard rev limit will restart ignition timing at the specified engine speed.
    By default this item is deactivated (being set at 8000rpm maximum RPM).

    When this limit has been reached the launch ignition timing retard will instead be used for off idle timing.
    It means that the current timing will be what you set in this field.

    WARNING: Using low ignition timing can cause high exhaust gas temperatures .
    Be very careful when using low levels of ignition retard.

    At this time it is not possible for the Nissan ECU to do negative timing (after TDC).

    Why are you suggesting it would not be suitable for an NA?

    I would have thought it would be very well suited for an NA.
    Using the fuel cut rev limit system is safer than the ignition/spark cut fuel dump system.
    Setting the right rev limit would allow efficient clutch dumps without the added stress to the clutch/drive train, or bogging down or breaking traction.
