Thread: 2-Step/Transbrake internal software question.

    Default 2-Step/Transbrake internal software question.

    Hey all. Might seem like a dumb question, but I want to ask. I'm using a Terminator setup as HP, and running an input off a pushbutton on my shifter to the ECU (through a diode to remove flyback voltage spikes) that doubles as my transbrake activator. I've setup my Rev Limiter #1 at 5300/5270. I wanted to confirm that when I activate the Rev Limiter on the switch, the ECU will automatically cut out the nitrous and not allow it to spray while I've got the TPS at 100%? I've set my nitrous activation RPM at 5500 RPM. Thanks in advance.

    If you hit any rev limiter, the nitrous shuts off no matter what. However, the problem is, the rev limiter works by turning on & off as the RPM goes above & below the setpoint. So you must enable & program "Input #1 Will Disable This Stage" when the Rev Limiter #1/#2 (2-Step) is activated. Then in the Pin Map, N2O Input #1 can be combined with Rev Limiter #1 on the same pin. This is software based, so no actual wiring.
    May God's grace bless you in the Lord Jesus Christ.
