    Default Bump Box Using SSR

    Guys, did anyone try the to wire a bump box to Holley with a single relay. If someone would share the wiring diagram, it would be great. I would like to use my transbrake & bump box for staging.

    Yeah, I included it in this thread (post #3), but I don't think he found it helpful:

    This is the Three Relay Version. This is my multiple relay version with a bump that you can set the timer & frequency.
    Takes 3 relays. 2 that are normal, and one Holley "Nitrous Driver" (which is a solid state relay) for PWM.

    When I press the transbrake button, multiple things happen.
    My transbrake output sends +12V to trigger a relay for the transbrake solenoid, and my bump PWM command goes to the solid state relay.
    It does this anytime I am holding the transbrake button so it is already on and ready for the Bump Button to trigger the change over relay.

    When I hit the bump button, it triggers the relay to change from pin 87a to pin 87.
    So it switches from constant +12V for the transbrake to a PWM +12V signal.
    (Remember, the Holley solid state relay uses a PWM- to trigger it, but it outputs a PWM+ signal to whatever device you are triggering.

    I use a non-Pin Mapped output for the bump button, and then I use a linked output to make the bump relay trigger output activate.
    So it only activates when I have the transbrake button pressed, and I press the bump button and it triggers for an actual bump time...and then shuts off. My "Trigger Time" output is the one that goes to pin 85 of the change over relay.









    It may seem a little complex.
    But it gives me normal transbrake control, with a bump button that I can adjust how far it bumps, how long it bumps, how soft or how hard it bumps.

    The way I have it set now, it's a pretty small bump, and it's smooth as glass.
    So I can stage as shallow or as deep as I want, by pressing the bump button once or multiple times.

    Can you use & install this setup on a Holley HP, or is it only Dominator EFI? Thanks.

    Yes, this can be used with the Holley HP & Dominator ECUs.

    With the EFI software version out now, we have option to use the bump SSR duty % over a set amount of time with the timer tab, right?

    I have my settings and wiring just like the post #4. The part that I do not understand at all is:

    The way I see it the Bump timer table will output PWM+ to the changeover relay for .012 seconds each time the transbrake button is on and the bump button is pushed? I'm not following the quoted area at all.

    Thank you for the wiring schematic for the 3 relay setup I have this completed. Would you have time to send the programming side of it? I'm pretty new to this. I just switched from BS3 to Dominator. I'm a little intimidated. I started to enter input trigger and when it came to drop down, this output will be activated when click on field and empty. Not sure where to enter if you're able to point me in a direction. Much appreciated, thank you.

    I'm setting up my transbrake and bump using V5 staging and the relay setup like this. I have a question about the time function in the staging I/O. I was expecting that it would auto calculate based on the frequency and duty cycle settings, but it remains at .999 sec. Do I need to calculate it like what Scott has described elsewhere and manually enter it? Or just leave it alone? I'm assuming if I leave it at .999 then I shouldn't be hitting the bump button more than once per second.

    This is by far the best I've come across. You can control it and make it so smooth: https://www.youtube.com/watch?v=Gf4jfzGGdss
