Throttle Response Units…. Thoughts?

Man. Arrogant anecdotal circumstantial evidence continues to be posted here by folks poo-pooing throttle controllers.
I disagree with your opinion that the right foot can operate the throttle exactly the same, if I hypothetically knew how to operate my right foot “correctly”.
I’m aware that what boosters do is alter the throttle input signal sent to ECU. Alter, meaning, increase the speed.
“That makes the throttle feel more responsive but it does nothing to the responsiveness of the vehicle”
Square that statement circle for me..
It does affect the responsiveness of the vehicle; via throttle response time.

Y’all are trying to make me feel like I’m taking crazy pills, but I’ve driven my damn truck before and after a throttle response unit. It’s different, for a reason.

 

Seems like it takes about an hour for the thing to move sometimes

 

Deleted my other so I could reply to this one but you cannot decrease the lag inherent to the system by adding a logic controller. Any perceived improvement is just a placebo related to the controller sending a wider throttle signal earlier in the curve based on your throttle input but the signal itself can't get there any faster.

Even worse, the controller must increase the delay before the ECU responds, even if only by a few ms, because you're adding a logic chip to the circuit. If the signal is delayed from the sensors in the pedal, you aren't sending them any faster to a controller and if the delay is with the ECU response, it's not going to respond any faster because the signal is coming from the controller.

 

100% incorrect

 

Thank you for this continued valuable contribution to the conversation.

 

Just making sure people aren't getting the wrong/bad information you are providing in this thread.

 

The signal is just a voltage (well multiple, parallel voltages for failsafe). Electricity over a wire travels at nearly the speed of light (it varies by environment but it's faster than is important) regardless of voltage, but electricity through controllers is constrained by the processing speed of the controller. The controller reads the input voltage, looks up the new value, and outputs that voltage on the wire. By the laws of physics, that process is going to be longer than just allowing the original voltage along the wire even if it's nanoseconds. It cannot be faster and thus, cannot decrease the lag.

 

These units are not useful to me. I think my 4Runner accelerates just fine. They may be 99.9% safe but I also don't want to leave anything communicating with the vehicle computer when I am trying to drive.

 

Incorrect

 

Would you like to elaborate? I've got some CE PhD friends that would love to hear your dissertation on the topic.

 

I have a sprint boosted but would love to do a tune. Last time I checked I would have to drive across border to USA to get it tuned. So if there is any tuner for a 4 Runner in Toronto area please let me know, I will crawl through the ridiculous traffic to get it done.

 

Throttle controllers do reduce the lag time, that is one of their biggest benefits. They do not increase hp, anyone who says otherwise is incorrect

 

How? Spare me no technical details.

 

There is Lots of information out there on how they accomplish the reduction of throttle lag.

 

Dude the whole reason throttle response units exist for sale is because they do a thing. You seem to be arguing they don’t do that thing. There’s no placebo. There is misconception by owners about what the unit is actually doing and not doing, yea.

 

It's ridiculous isn't it? Too many internet posters that don't have a ......... clue. Smh

It's funny, all I can find is marketing sheets did you have something better?

They do a thing, but it's not what people think it is. Vague marketing claims are a hell of a drug.

"Throttle response" does not mean it makes the ECU respond faster, it means that for every degree you push the pedal, you get a greater value forwarded to the ECU. Instead of sending the signal for 25% at quarter throttle, you instead get 40% or 50% or whatever it's programmed to send. It's "increased response" means you are getting more power at the same pedal angle, but there is zero difference between that and moving your foot to send that throttle angle manually.

 

@2016Pro That is true, but I will day the whippersnapper isn’t some kinda poser at all - we just may have small disagreements on particular things sometimes.

 

He's a hopeless dolt this one lol. Smh

 

Yes, not him the other...... well you know

 

Great write up by @Agent_Outside

Don't you have an unattended bridge somewhere or have you finally rubbed enough brain cells together to contribute to the conversation?

 

Derek:

Lost Woods: They do a thing, but it's not what people think it is.


right.

 

At this point it's entertainment lol. What a happless dolt lol

 

I'm confused are you saying that I'm right or wrong?

 

Haha

reminds me of Ben Shapiro’s funny use of the term “dolt”, and phrase “that is correct”

 

Yeah fuck me for trying to stop the piss poor information that radiates from these threads.

 

Right, in that you’re agreeing with essentially exactly what I just said.
Wrong, in my opinion, in how much of an expert you and your genius friends are.

 

Yes, what's that saying? You can't fix stupid.

 

The problem is that people are talking about two different lags.

1. Lag between pedal push and message to throttle
2. Lag between pedal push and some acceleration threshold of interest.

Any controller in a causal system (i.e. one that can be implemented without time travel) has non-zero processing time, so a controller can not get a message to the throttle any sooner than the system did without it. **

However, the characteristics of the engine are such that despite the throttle getting the message a hair later, a well-designed controller can enable reaching the acceleration threshold of interest sooner for the same pedal input across a wide range of pedal inputs.

** Note - a tricky controller could allow the unfiltered pedal message to reach the throttle undelayed and send an adjustment instants later. Under that circumstance tricky controller could tie the unmodified system for first message and for an instant system performance of the modified and unmodified systems could be the same. This version of controller would also just result in behaving like a regular gas pedal if it failed.
