In case you're unfamiliar with numbers and math, that is 0.075 second. And the time is less than that.

Shall I dump the data to an excel file with timestamps too?

This is what the car's ECU sees. Therefore there's absolutely no delay in the pedal. The pedal is a pair of hall effect sensors, not the complex circuitry you are suggesting.

Do you still believe in promoting your snake oil SGREENLYN?

Would you like to see the graph from my 2013 Hyundai too?

And before you suggest using "Torque", their displays are heavily overdamped to make gauges look pretty as they move.

If you'd like to see the data from another source I can communicate with the vehicle using proprietary protocols too.

But I think we're done here...

Go back to whoever is paying you to do this and submit your resignation.
Yes that's all well and good having hard facts and evidence - but have you seen the You Tube videos???

Even better, have you tried it? When I select the economy plus map, the Jag takes over 10 seconds to 60 mph.

You said throttle maps make no difference.

So 12+ seconds is the same as 4.8 seconds?

What???

So, you've proven that the device can make the response slower. Nobody is disputing that.

That does not mean it can make what is already NO DELAY faster than NO DELAY. Can you comprehend this please?

Time travel is not possible in your pedal gadget.

ZERO time is the best you can do. It's already zero. There is no negative time.

I've owned one of these devices for years on another car.

They do indeed have the ability to add delay or alter the linearity of the pedal output.

But the car can not be made to go faster by "removing delay from the pedal"

Repeat after me: There is no delay to be removed.

It is 100% bunk. Period. End of topic.

Mods please lock this thread, because this is ridiculous now.

You're arguing against yourself again. If the problem is in the pedal, a different ECU map won't help. I didn't reflash my pedal. I reflashed the ECU. Software changes won't alter hardware.

Whoever said that is misunderstanding what was actually done, and has the same comprehension of throttle mapping as you do.

"Throttle mapping" sounds technical though, like something someone knowledgeable would say.

Of course these devices can make a difference for the worse. According to the diagnostic gear results above the standard pedal takes less than 75 milliseconds to register WOT. Dropping that to 20 milliseconds is not going to make a difference to your 0-60 times but making it 5 seconds will of course but why would anyone want to do that? I already have Winter mode on my car if I want to pull away in a more controlled manner.

My accelerator does have a built in delay and it is called my right foot. If I mash the pedal in to the carpet from standstill with the traction control off my rear tyres disappear in to a cloud of blue smoke. 550bhp has a habit of doing that. I therefore have to ease the throttle to take off cleanly. Making the pedal register WOT 20 milliseconds earlier will have no effect on that. You have a lot more traction available with AWD but a few milliseconds here or there is going to make o difference to your 0-60 time.

As mentioned by others the device can be configured to make the throttle more or less responsive but it won't affect your 0-60 times. The only way you can do that is to make changes in the ECM because that is where the delays and torque limiters are.

What???
When you set to economy plus and log data, what do you see for throttle position?

OBVIOUSLY that means another throttle curve is faster. You've finally seen the light!

So now that we all agree that throttle maps are both slower and faster, let's move on to my question. Which device is best suited to the F-Type?

I have a Sprint Booster in my tuned BMW 135i before Terry Burger's legendary JB4 tune embedded throttle curve re-mapping in a firmware update a few years back. For the record, I do not recommend the SB over others I have tried.

Sooo...Notice how we have to rely on the Sprint Booster to indicate which setting is the actual OEM response rate? None of these demonstrations provide before and after installation results. Clever high tech shell game.

Doh...I promised myself I’d stay out of this. Sorry guys, couldn’t resist.

Nope, because the throttle curve is in the ECM not the pedal which is why people pay for tunes. You are arguing from the point of view that there is some sort of delay built in to the throttle pedal and it has already been conclusively demonstrated that there isn't so your argument totally falls apart at that point.


The best you can achieve with your device is to get to 100% WOT a few milliseconds sooner which will have zero impact on your 0-60 time because it is the ECM that is taken the throttle input and using its maps to decide what to do next. Which bit of that don't you understand?

I see now we've moved into the advertising part of this. Casually we're all going to be tricked into conceding that the one he's paid to promote is the "best", since it makes the fewest fraudulent claims. First get the eyeballs with controversy, then the "oh look at this one, hmmm..."

Unless you can accept the fact that 1) the pedal has no delay and 2) that your entire premise is completely wrong, you have zero credibility here, just remember that.

This is like trying to teach economics to a toddler.

I'd be interested in some premium blinker fluid. Can you please direct me to a seller?

Speaking of fluids and YouTube being the only viable reference source, these appear applicable to the subject matter of this thread

So now you are going to argue that throttle curves make all the difference in the world??

Anybody using one of these? It's one kind I haven't tried?

I suggest a break in the festivities and have OP show some photos of his IRR f type.
