Iíd really like to run one but canít figure out how to wire it so itís only active for 1st gear when I wantÖ. I was thinking have a switch hooked to a 1st gear indicator but canít figure out how to do thatÖ.

looks like it only delays when the circuit is closed.
So install a simple button anywhere you can reach when you are launching.
In the video they made their staging brake close the circuit. Which makes sense.
But that button can go anywhere within reach.

It doesn't seem to need to be more complicated than that.

You could maybe hack the ecu to supply voltage while you are in first gear.
But seems way more complicated than just holding the button when you are launching, to me.

EDIT:

Or you could mount a switch in the shift linkage that is only pressed when in first gear.

I thought about holding the button also but what if I forget to let go? Or I let go a second too early? Just a lot of pressure during a racing situation.

I thought about a first gear switch but havenít figured out how that would look. Guess Iíd have to make a little bracket with a push button switch that sits in the shift linkage area but not entirely sure thatís the best route to go.

I think it makes the most sense on a staging brake. If you had one of those to preload the drivetrain you'd be holding it anyway.

You could rig a button just in reach of a finger when you hand is in first gear. Hand on shift knob, finger pressing the button. No way you would forget to let go of the button since you wouldn't be able to reach it from second gear anyway.

Another option might be a simple time delay relay that energizes the circuit for .5 seconds after you press the button. Though I think that would be too fiddly.

Not really any where near the shifter I could put a button and shift at the same time without making some contraption.
I canít throw it on a staging brake because as soon as the light comes on, I let off the stage brake so it would cut signal to the slip device.
I also agree a delay relay would be too much to adjust and play with

I just went to my car to test it out.

Use the button like it was a staging brake.

By that I mean place it near the shifter. You don’t have to have your hand on the shifter when you’re in first gear.

When you release the clutch your hand moves from the button to the shifter. (The exact same way your hand would move from the staging brake to the shifter)

And since your hand is on the shifter you’re never pressing that button again.

Was thinking like this

Don't mind the dog hair.

The button doesn't need to be large.

Trying to think of a way to do it without putting the switch in the linkage.
But at the end of the day a switch that is pressed by the linkage when in first gear is probably the best way to do this.

The other way would be some kind of arduino/microcontroller, that reads canbus and sends out a voltage when you're in first.
MotorvateDIY could probably do it, but probably does'nt have time to.
Also, I would never opt for this canbus solution when a mechanical solution exists (the linkage pressing the button directly)

But if I move my hand too soon from the button to the shifter it could cut the slippage short right?
So say light drops and my finger is on the button, I drop the clutch and move my hand to the shifter and that kills the clutch slip. The device has to be engaged for the entire 1st gear from what I understand.
I appreciate the input!!

Also I canít see the dang picture

yeah i think that the solenoid will go full open when the voltage is removed

you could have a latching circuit too
you press the button once
the delay function turns on
when the clutch reaches full extension, it presses another button. that turns the delay feature off.

Way more complicated than the button on first gear tho. But it has the advantage that if you don't enable it before releasing the clutch it's effectively always off.

it's an interesting problem to think about

What if I had a switch to arm the system/clutch device and then another switch hooked to the clutch pedal and when I go to shift, it kills power once the pedal is depressed or even kills it after the pedal is fully released

that's exactly what i was trying to say.
latching switch (aka arming switch)
momentary press turns on the circuit, engaging the delay device
when the clutch reaches full extension, another switch is pressed turning off the device
device stays off until you press the latching switch (arming it)

i don't think a switch on depress will work. since you would "arm" it and then press the clutch in de-arming it instantly.
