    Guy with sts turbo says they are giving him a two step in software is this possible?

    Like the title say. Local guy got sts turbo and the sts guy told him he can give him a two step in software. I didn't think you could do this on these cars.
    I had to buy hardware msd two step to do it supposedly. Be a bit ticked if can just do it in software.
    I can do it with software in my talons no problem.

    sts 2 step

    yes, Rick can install a 2 step rev limiter into the tune if you use the predator tuner. What I had to do was have the tune downloaded via the internet to my predator then loaded the predator tune into the car then copied the tune into my hp tuner and it works perfectly.

    set the park/neutral rev limiter to what ever you want and any time your foot is on the clutch it will enable the limiter

    So this is six speed solution only obviously. Auto guys would still have to buy the msd or other two step. Since revving it in neutral and slamming it into drive would not be a good thing.

    That's why you stall up in gear...

    Still better off with a real launch controller. I used that method and you need the mod for the clutch so the switch isnt so sensitive, leaving you bouncing off a 3600rpm limiter between shifts isnt cool. Even with the mod for the switch I wasnt happy with it and got the lingenfelter launch controller.

    Thumbs up

    I changed my park/neutral limit to 3500 at lunch yesterday. Works just like a 2-step except it doesn't quit until the clutch is fully engaged (pedal all the way back up). I suspect this will result in slower 60' times at the track, but I plan to experiment with it this Friday evening. The other cool benefit is being able to flat foot the throttle between shifts.
    I would be interested in knowing what this is "the mod for the clutch so the switch isnt so sensitive".

    The Fuel Cutoff RPM vs Gear table also has two columns between 6th gear and P/N. What are those tables for and how can they be controlled? Is it possible to trigger those two columns with a pushbutton similar to the clutch switch?

    The problem is you have a fuel cut and it can make for a worse bog. Also, in 6 speed cars there are instances where the P/N fuel cut will activate in gear as well, rendering it useless.

    The mod is a relocation bracket for the clutch switch (available from STS). It moves it up maybe an inch or too, cant remember. It does make it so you have to be careful with using the clutch to disengage the cruise control. And I have experienced those instances where it activates in gear, thats why I gave up messing with it and got a real launch controller.

    from all i read before it is not good to use that as a 2step because it cuts fuel and not spark Which people say it could cause issues eventually from being so lean.

    I myself have used it before without issues but I am just telling what I read.

    cutting fuel is not a lean condition...
    no fuel = no mixture

    its actually safer than cutting spark
    when you cut spark you can wash down the cylinder walls if you lean on it too long...

    when you cut fuel you just have a spark plug making commotion with no fuel to ignite... no worse than making the plug fire in free air outside of the engine.

    yah but u might have fuel still there in the runners do you not ??? which could cause the lean issue.

    Again like I said that what i have read. I have used this before and it works great for me

    our injectors are set up to fire completely before the intake valves open(on a stock cam)
    on our aftermarket cams.. the injector has completed long before the valves close..
    you shouldnt have any fuel hanging out in the runners with that...
    and if you do it will be such a small amount that its not going to matter anyways and will not light off..

    theres just not enough fuel to worry about with a fuel cutoff style limiter..

    you may see a lean reading on a wideband o2 sensor because of the gap between real injections and fuel cut and the nature of our software that averages data


    a spark cut is faster and holds the rpm better than a fuel cut...but a fuel cut is cleaner and in general safer...unless you are spraying Nitrous... then it can be very dangerous if not set up correctly
