Limitless Perfect Pass Tuning?

[sert rc]

What’s up guys. Can anyone share tips or best practices when it comes to setting the potentiometer on the Perfect Pass?

Are there any clues in the data logs that correlate to a longer or shorter time to hit full throttle? What do I need to look for to determine if I’ve set a good time to full throttle?

I just hit a PB of 120 on a new road that’s about a mile long so I’ve got plenty of space. Pulled 380amps on the XLX2 with a 1520-1650kv motor so there is room to gear up some more, but I wanted to make sure my pulls are tuned right.

Following for the answer to a real good question.

From what I’ve heard, the more gradual the ramp up the better. I think the PP has a 6 second max? As long as you have the room (and the eyesight) your amp spikes will be reduced. And now some of the true experts should weigh in, as my current PB is still somewhere in the ‘70’s and I’ve never used a Perfect Pass!

I have no experience with perfect pass but a slow steady trigger pull makes a massive difference. Focus on a squeeze and let it be a surprise when it bottoms out the trigger. Get used to that then work on thow long your squeezing. Longer pull is less amps. Higher voltage is something i have no experience with either. Honored to be mentioned in the above company however.
Appreciate the acknowledgment @Dan B.
Hope you can get out there and get that pb up brother.

So in other words, the slow continuous rise is what's wanted? No "hold off there for a second or less and let the motor get its rpms up and then start applying more throttle"?
One thing I was always curious about with how PP works. Is it programmable, like with Castle's throttle control via Link(can be "linear"), or is it a just a timed throttle release where no matter if you jam the throttle all the way back, it will take the whole six seconds before full throttle is applied?

Yup, it has a pot adjustable to slower/faster ramp up. It’s linear. Just pin the throttle and let it hum.

I use perfect pass and I have tried it at different levels. Turned it all the way up and jammed the throttle and it was fun to see how it slowly climbed…

Don't have one, but should be fairly simple. It's all relative to your setup and runway.
You want the lowest/highest possible ramp that keeps amps within reason, and you see an overall gradual increase of throttle/amps/rpm.
Avoid or minimize any spikes. Obviously the slowest setting is theoretically the best from a stress point of view, but if you have 6s ramp up and 2-3s full run you need very good eyesight and a long runway. From what I gather, a 2-3s ramp should be the happy medium.

Yesterday I perfectly passed a senior doing 40 in a 55mph zone.

There is no perfect setting.
As you try different gearing and speeds you will find extra speed by adjusting this dial differently.
In general somewhere around the 6-10 second range is where you want to be (the count in seconds is only visible from the castle data logs)

It could be that for your 120 speed, 6 seconds works great, and for 150 mph speed, an 8-second setting works best.
You could change lipos and then need a different setting yet again.

As Raz says , it must breathe. (Motor)
Need to match the throttle duration rate to the distance you are running. In theory, if the space is too short, it never breathes. PP still has some more Throttle input to reach. The data logs should show that you reached 100% sustained power somewhere in the PP timed throttle duration. Every setup is different. Trial and error.
Check out Raz's videos in regards.

You just want more than 2s at top speed to get a good run with the highest possible speed. There is typically no more acceleration after 2-3s at top end, and you only eat up ground. Getting there with minimal stress but within visual and RF distance is the trick besides exploding tires, bumps in the road etc.

It is just so hard to do in reality when the road runs out of length.
At 140+ mph the car is eating up road fast. I cant go beyond 7 secs with the road I have.

The higher torque motors would probably shave off some required distance.
And Probably why dual and quad motor setups are getting the Best PB's?

As everyone has said it’s all relative to speeds/cell count/distance etc.
I myself do not use a perfect pass. Although I have gotten a few for friends to setup in their cars and have tried it testing and I don’t care for it honestly. Up until recently I had no aids on throttle but now that I have upgraded my remote the throttle speed can be adjusted to soften my throttle inputs/remove some of my throttle jumps and I’m more than happy with that. I recommend learning without a perfect pass because it’s going to make you a better driver imo.
Here’s my 183mph 6s pass, once car was locked in straight I steadily increase on my own pace and the numbers speak for themselves

Wow, that log shows you have one steady throttle finger there.
I find that even Radio Thr. EXPO helps much.
But most any decent radio will have Channel Speed control settings. Basically what PP is.
