    2 step

    Hey is anyone running a 2 step system on there bmw? What make did you go with and how hard was the install?

    Also all i seem to see is turbod car running this setup, can a N/A car run it also with out a problem i know its for antilag, but could you use it as far as normal launch control?
    Thanks,

    A two step is a secondary rev limiter, not antilag. The purpose of a twostep is to allow a consistent launch on a drag strip.

    I've had whats called a "WOT Box" on my car for ~1 month. The unit had very promising features such as a two-step launch control and no lift shit (the unit could temporarily cut off the ignition for a pre-set time so that your right foot can remain on the throttle while you engage the clutch and shit into the next gear). According to the guys at http://www.npcompleteperformance.com/wotbox I was the 1st one to try it on a bmw. They sent me a wire schematic. After that the support was non-existent.

    I got the no-lift shift to work (sorta), but the 2-step, the main feature why I bought it for, never did. I took it to the 1/4 too see what results can be gained from the no lift feature and it threw a CE light so I pulled it and looped the wiring..

    Still have the box if someone wants to give it another go.

    There are some BMWs running at the drag strip with a twostep and some with antilag (some with both).

    You run antilag to build boost at the standstill (to make boost from the hit) and you run a twostep to launch the same way every time. Having your twostep dialled in just right means a couple of good things for drag racing. First you don't have to worry about using your right foot to find the optimum RPMs for your launch, instead you can concentrate on the Christmas tree. Second you can't overrev the engine accidentally. Third you launch the same way every time so you know what to expect.

    You use the antilag on the line to build positive boost on the hit. Be careful because too much boost will mean you blow the covers off and that means a shitty short time.

    I have got my N2mb wot box to work some what, the problem is that it stops at the revlimint for half a sec and drops down 1k and then it goes past the set rpm and jumps around like that. No lift shift works fine with no engine code (disabled miss fire detection past 2500 rpm).

    Anyone know what might cause it to jump around?

    What was the problem with your wot box?
    Did the rpm jump around?

    N2mb

    Where did you source the rpm signal? I had this issue when I tapped into the fuel injector for rpm signal. I tapped into the Crank Pos sensor and it holds the 2-step now with no rpm drop or spikes.
