I drive a Honda City CVT and was unhappy with the pick up of the car especially the lag that kicks in around 40-70 kph. I did speak to a lot of people getting opinions and suggestions of what can be done..
Another BHPian advised me to try out 'Pedal Tune' by Mithun and Narry mentioning it's more of a plug and play system. So decided to get it installed in January this year (I know I am late in posting this!).

And guys I have to say, this is an amazing product!!
It has removed the lag to a considerable level and improved the throttle response. The car feels much lighter and peppy and, overtaking on roads has become much easier. The economy -2 mode also has a better pick up than stock and improves the fuel efficiency to a decent level.

Although, I would still say there is some bit of lag at mid speeds but I believe that's how the car is and obviously you can't compare to a turbocharged engine.. However, Narry has promised me to look for a solution for this also!

I do not have lot of technical knowledge but as a layman I would suggest this product to people looking for better pick up and fuel efficiency in the car.

Pedal Tune Box Experience in remapped Polo 1.6 GT TDI
I got to drive a remapped Polo 1.6 GT TDI with pedal tune box from Narry. This was my tuners car (Rajiv). Rajiv had come down to Mysore to remap few of my friends cars and Narry was also in Mysore and we all met

Narry offered us to provide demo of pedal tune box in Polo. He installed the box in 10 minutes. I too got to test the box and tested in all modes.

I was going mad and it felt like the car has become much more powerful and fun to drive. Just tap the pedal and car used to fly. Whenever I switched back to stock, the car felt like it was not moving at all. I was enjoying the drive like anything.

Is the Car more powerful? Any gains?
Big NO!!

I did full throttle runs in all modes and it was as good as stock. We did not find any difference under full throttle. So I am very sure that the box won't have any power gains or significant improvement in 0-100 timing.

What does the box actually do?
1. It makes the pedal respond much faster.

2. WOT effect is achieved with much lesser pedal input.

Conclusion :
The car definitely feels fun to drive and at sports mode it just flies with tap on throttle. But we do have to understand that we can achieve the same effect by 100 percent throttle. If the buyer is looking for power gains / good improvement in 0-100 timing.. This box is not for you!!

I had tried pedal tune box from Narry / TTS auto few months back in my S-Cross 1.6. The box did not work and there were couple of error codes and A pedal was dead with non working AC. The culprit was wrong pin outs in pedal tune box connector.

Narry sent me 2 more pedal tune boxes to try and I got to test it today. History repeats and the same problem. I have tried 3 pedal tune boxes from TTS auto and none of them worked, thanks to wrong pin outs. Anyways Narry wasn't sure if it would work and had informed me in advance . I will test the pedal tune box again if Narry tests it in some other S-Cross and confirm about the compatibility.




Note :
Narry had sent these boxes to me only for demo / testing. He has not yet tested this box in any Indian S-Cross before. I was fully aware of the consequences that the box might not work.

Slightly OT, but this post of mine may help people interested in 'pedal boxes'.

I ordered a DTE PedalBox from Germany a couple of weeks back. Landed cost through UPS: About Rs. 21500 including Rs. 6,500 as import duty. I fitted it myself as the Thar's throttle connectors are quite accessible.

The box works phenomenally well on my Thar CRDe, in terms of improving driveability. The Thar suffers from prominent turbo lag under 1,800 rpm. This box makes it seem as though the lag is almost absent. Going through the gears is also very enjoyable now as the revs don't drop. I'm able to stay in the meat of the torque band. Overall, I'm pretty happy with my purchase as it's made everyday driving more fun without me having to fiddle with stock code/mechanicals.

Cheers,

Jay

This is exactly what I'm looking for since i got my Polo GTI! I was driving a 2008 Honda Accord 2.4 before this, i suppose it didn't have DBW and the throttle response was much better. Even my brother's 1.8 Corolla seems to JUMP if you barely touch the throttle! But the lag in my VW is unbearable! Where can i get this in Mumbai guys? Thanks in advance!

[zebanaff]

So Frank hooked me up with the pedal tune box for my Skoda Rapid 1.5 TDI, and my mind is blown. Just did a Mumbai-Goa-Mumbai trip with Race mode +1 and it was just the smoothest, must fun drive of my life. You don't really feel the difference until 3rd, 4th and 5th gear. At any point over 1500rpm, she just flies and revs like a petrol engine. It's absurd! I don't think I can ever go back to stock again!

[satyahanspal]

Hey! Can you connect me with frankmehta? I'm looking to buy this.

I had a friend call me at 8 something in the morning recently asking if I could install a pedal tuning box on his Isuzu Dmax. Now those of you who know me, know i'm not a morning person, so I was a bit confused as to what he was on about. It took me a few moments to register what he meant, all this while him telling me that it will take 5 mins and he will gain a bunch of torque.

I started to explain to him that it’s just a gimmick and does not actually work any better than a patient in a medical trial being administered a placebo. Still not convinced, he started telling me about friends who installed and were shocked with the increase in power and torque.While they may have been shocked, trust me, their shock fails in comparison to mine upon hearing this.I then understood how partial information or deliberate misinformation propagates, and people with little to no understanding about how the Control Unit of a vehicle functions, “Pedal” goods to make a quick buck

So here is the most oversimplified explanation that I put together for my friend, as to how and why a pedal box cannot make ANY more power or Torque. It CANNOT increase 0-100 or ¼ mile timing either obviously.

We first need to understand how the Stock car works and what exactly happens when one presses the pedal. Please understand, I have oversimplified the process for the sake of this article and omitted a lot of irrelevant information.

Driver Presses Pedal-------> Ecu looks up “Drivers Wish Map”------> Determines how much torque-------> Converts Torque to Fuel Injection-----> Filters this value through Various Limiters-----> Injects Fuel-------> Driver Smiles.For the Purpose of this article we are interested in only step 1,2 and 3.



So let us look at the drivers wish map, fortunately or unfortunately the Isuzu Dmax has a very simple and linear Drivers Wish map, expressed in %torque.Here the:-

X-Axis is Engine Speed in RPMY- Axis is Pedal Position in % (0-100)

Area bound by the Axis is %torque request.

Important Note: The pedal position is determined by the TPS, ie throttle position sensor. It is an Automotive Rotary Potentiometer which outputs a voltage between 0-5V (actual working range varies by manufacturer and application.There are also two or more sensors which read inverse of each other, to ensure sensor failure does not result in ecu thinking 100% pedal) after taking a 5V reference Signal. For Ease of understanding,

Let us assume 0V is 0% pedal and 5V is 100%. This means 1V=20% 2V=40% 2.5V=50% 3V=60% 4V=80% and 5V=100% or 20%=1V and so on and so forth.

On the Stock Car if the driver presses the pedal 20%, the TPS sends a 1V signal to the ECU. On our Isuzu with Transton Engine management this relates to 20% torque request, regardless of engine rpm. This %torque is now looked up in our Injection Table which correlates engine speed with %torque request and then decides how much fuel is to be injected.

If we press the pedal 50%, the voltage signal to the ecu is 2.5V. If we press the pedal 75%, the voltage signal to the ecu is 3.75V

What the Pedal box does is it connects a signal amplifier, between the accelerator pedal and ECU, this manipulates the signal to the ECU.Lets say on its “race” setting ( I think #14) the box adds a amplification of 50% while capping voltage to 5v thanks to the 5v reference it is piggybacking off of. Now when I press the pedal 20%Voltage out of TPS =1V Voltage intercepted by pedal box =1V, this is amplified by 50% and then sent to the ECU. Voltage received by ECU = 1.5V. ECU interprets as pedal press of 30%

Now when I press the pedal 50%Voltage out of TPS =2.5V
Voltage intercepted by pedal box =2.5V, this is amplified by 50% and then sent to the ecuVoltage received by ECU = 3.75V. Ecu interprets as pedal press of 75%

Now when I press the pedal 75%Voltage out of TPS =3.75V
Voltage intercepted by pedal box =3.75V, this is amplified by 50% and then sent to the ecu. Voltage received by ECU = 5V ( The Reference 5V limits the output crossing 5v, irrespective of amplification)Ecu interprets as pedal press of 100%


So as you can see here, all that changes is the pedal position input to the ECU, after the input lookup, the ECU will jump to the exact same cell in the fuel Injection table.For all pedal positions of 75% and up, ecu will only read 100% pedal.

Since it is not possible to go above 100% pedal or 100% torque, the car DOES NOT make any additional power and torque.The “ Increase in power and torque” is purely psychological and is only felt as one feels that the car “flies: with minimal pedal input, when in reality that signal is being skewed and fed to the ECU. One would get IDENTICAL results if one was to just press the pedal more.A very good non technical analogy would be imagine two cars with identical music systems, only difference being, one had volume control from 0-30, and the other had from 0-10If one was to play both systems at volume 5, most people would think that the second system is “louder”. It is this misconception and misrepresentation that the pedal box industry thrives on.All the pedal box does is rob you of throttle modulation

[Tassem]

I'm just tired of theorists giving the Pedal Tune so much flak. So far, of all the critics, I haven't seen one person who's actually used it except maybe for a test drive or in most cases just reading up about it or looking at the packaging. I've been using a Pedal Tune on my Isuzu for over 2 years now and let me tell you, I'm never going back to stock. I can introduce you a lot more people who are regular users of the pedal tune and they will tell you exactly the same. The only thing the pedal tune robs you of, is the nannying. As for throttle modulation, it gives you a lot more. The difference is in how fast the throttle body responds to your inputs.

The issue is that some people love to stick to numbers while others go with what they feel. If a car feels faster, it doesn't matter if it isn't faster. What matters is that the pedal tune will 100% bring a smile to your face everytime you drive it. Every single time.

Think of it as a sports mode button that just tightens everything up. No extra power, but sharper throttle. Also, it's 100% linear. You can keep the RPM at any number as you please. So the assumption of ECU reading 100% at all inputs above 75% is not true.

Also, the thought process that just pressing the pedal mode will give you similar results is again hogwash. Unless you're the flash and can move the pedal at the same speed as an electrical signal. Also, no matter how fast you can stomp the pedal, it will simply not respond the same way.

People only talk about the race modes. But the pedal tune also has eco modes that reduce responsiveness to give you much more finer control over throttle, especially in tricky off-road situations. As for race modes, you have to drive it to believe it. My remap came to life after the pedal tune was installed.

Oh and one other thing which hardly anyone mentions - Pedal Tune also works on lift-off. This means that less fuel is used to smoothen your pedal inputs while decelerating which directly translates to more mileage. Yes, more mileage. If you look at the way the RPM rises and falls when on race mode, you'll know exactly what I'm talking about. This does make the drive feel less smooth in stop and go traffic. But hey, why use race mode in stand still traffic anyways?

A pedal tune works because it removes the illusion of throttle control and gives you actual control. Ever wondered why your vehicle feels peppier after a spirited highway drive? Wish maps. The pedal tune makes your vehicle feel like that all the time. If we have a show of hands on how many have actually used WOT on their vehicles, it'll tell us why people feel they're suddenly generating more power. It's because you're taking the pedal places it's never been to before!

I keep wondering why people talk about increased BHP and Torque. I don't think the manufacturers are to blame here. The ONLY thing it improves is the responsiveness. Almost analog feeling. No Nanny.

There are hundreds of other videos on YT from real world users. Just search for sprint booster, throttle tune, DTE pedal box etc.

https://www.youtube.com/watch?v=Bbn7hI1kpA0

A product shouldn't have to be the recipient of hate because users don't understand it. It's not a gimmick, it's not a placebo. I'm yet to meet one person who's used it and did not come away impressed. The issue in India is that we have a lot more wannabe tuners than actually tuned vehicles.

Try the pedal tune once. I'd be surprised if you didn't buy it.

P.S Let's not talk about forced DPF regeneration etc because of the highway example. It's just the closest example I could think of.

[Tassem]

Here's a real world (not so scientific) video on the impacts on 0-60 times.

The thing is, even on performance modified vehicles, we're simply not quick enough with our inputs. Look at driver input data for race drivers and you'll see how much more aggressive they're with their inputs. The pedal tune simply fixes the lag both in our input and in how the throttle body operates.

And here's how wide your grin will be once you try it out for yourself:

Hello Fellow Bhpians

Was considering throttle controller for my BS6 Endeavour 2.0

As it's just a one year old vehicle, Is it advisable to install the controller considering warranty void issues.

Any experiences with the warranty claims....

[nTorq]

Does anyone know where I can get PedalTune in Bangalore?

[BODHI25]

Reviving this old thread again after a very long time.
There are new similar products on the market, like the Pedal Tune, which are slightly more advanced but, at the end of the day, does the same thing that PedalTune used to do. The two most popular products right now on the market are GotBoostPro and WindBooster, both of which cost somewhere around 17k these days.

I'm curious to know who all is still using PedalTune to date. Did anyone face any issues with this device? Let's discuss, and let's also have a long-term review.

Avi has mentioned he sees the fuel efficiency reduce. The clutch will get a beating cause there's no gentle use of the clutch.

So it would follow that you believe, for example, that those highly responsive pre-CRDe Scorpios (2002-5 ish) experienced a lot more accelerated wear in clutch (and as many are claiming here, drivetrain, etc) than the otherwise mechanically identical (but more sluggish) CRDe versions of 2006-onwards? In fact the opposite was true.

And owners of those vehicles, being that the old Bosch VE mechanical injection pump was indeed pumping in a lot more fuel a lot earlier/ quicker, were for some unknown reason unable to use their clutches gently?

Many here are forgetting that poor throttle response is a function of aggressive emissions controlling, we are not building race cars here, or attempting anything more than returning response performance levels to what they were earlier.

I'm sorry, but practically 100% of clutch wear in any car stock or modified occurs when it is not fully engaged, i.e., when foot is still applying pressure against the pressure plate's springs and there is some slippage occurring. Some people (incl. my father-in-law, who finishes clutches in about 20k km's) are notorious for delaying / extending the time for clutch engagement, either "half clutching" (even 10% would do), or giving too much rpm, or both.

And owners of unresponsive Thar/Scorp/other CRDe's tend if anything to need to slip the clutch more, to compensate for that low/delayed fuelling situation off the line.

If your throttle responds quicker, good - you simply adjust your clutch pedal release time/ pressure accordingly. Any driver who is in tune with his vehicle's operation and behavior would do this easily and naturally.

I've owned and driven plenty of modified cars in a spirited manner, never have had a premature clutch failure.

This is just more worrying about nothing.

The easiest and cheapest way is to have a throttle body operated by a cable or levers. Interestingly enough that is exactly what Jaguar chose to do on its 400BHP, 4.0l, supercharged V8 XJR/X308.

I’ve experimented somewhat in the past with various of these boxes on both petrol and diesel engines. Always left me underwhelmed. If anything, I found that the simplest of ECU upgrades where able to produce far better drive ability and throttle response than whatever box you add. And a lot cheaper too, for most cars.

As you mention a lot of our current throttle response is a function of emission controls. These boxes won’t fix that, a simple ECU tune will.

However, here in the west either modification is likely to incur the wrath of the respective manufacturer when you bring in your car for a service. BMW, Mercedes, Volvo dealers won’t touch your car if you bring it in with a modification. You will have to pay them to undo the modification before they will even look at your car!
