Went for a drive in mates 180sx today, we just wired up the MSD ignition 2-step launch control and took it for a test
due to such a large turbo, it used to always bog down off the line and people would always get the jump on us
2 step has completely transformed this car. First launch we did went something along the lines of this.
1st, Massive wheelspin
Grab 2nd, back end steps out, creep up street sideways
Grab 3rd, back end straightens up a bit, then slightly slides back out the other way
Grab 4th, back end straightens out, still wheelspin, then backed off
did a couple more launches and each launch got a bit better, really needs stickier tyres though...and this was still set up hard. With the dampers set soft, wider and stickier rubber this thing would launch like a bat out of hell.
