Thread: AOD & Bump

    Default AOD & Bump

    I use a LenTech AOD. Its transbrake is ground activate. The output from the Dominator is also a PWM−. Has anybody done this? Does it still need the SSR? Is current draw still a problem?

    I have a Lentech also. The ECU needs a protected input to your rev limiter when the brake button is pressed. Because we need a ground activate, and transbrake buttons are not really high amp capable, I used a relay. The switching side gets key power, and it’s ground is from my button, which also sends my Rev Limit #2 input to the ECU. The switched (high current) side of the relay is a ground in and a ground out to the transbrake.

    Do you bump stage with your AOD?

    No, I do not.
