We have discussed in length about Pedaltune and have heard/read different opinions about the same. But I have a question: What are the adverse effects of such a product? We know about the tuning box/remap that it affects the engine's long term life, so in the same way what con are we looking at wrt Pedaltune?

Absolutely NONE*. It's just like pressing down on your accelerator faster.

*Unless the PedalTune is dumb enough to go outside the original range of voltages sent back to the ECU. In which case all you'd get is a check engine light, but still without any damage to anything.**

**Unless the Pedaltune is so incredibly dumb that it fries the ECU with a really high voltage due to poor circuit design / lack of in-built protections.

Ill try explain the perceived wear tear situation with equations

• Remap (Re)
• Paidal Tune (PT)
• Normal driver (NJ)
• Aggresive Driver(AJ)

Re + NJ = PT + NJ
Re + AJ > PT + NJ
Re + NJ < PT + AJ
Re + AJ > PT + AJ

Hope this helps.

What wear and tear are we looking at wrt Pedal Tune alone? From the above set of equations it seems that a remap coupled with an aggressive driver is the worst combo (which does make sense), but from the 3rd equation(Re + NJ < PT + AJ), it seems that Pedaltune is worse than a remap (coupled with a normal driver) ?

Also i have read at various online places (Eg- Racechip) that a pedaltune (Racechip calls it Response control) would compliment a tuning box very well, so what will the equations become then?

What will happen to a car engine if driven with a constant heavy foot? for any given road situation speed load etc? Pedal tune with aggressive driver hence would put more stress, in comparison to a remap and gentle driver. Won't it?

Re + AJ = Rt + PT + AJ

So you can say Re = Rt + PT

Well this looks like a debatable topic because of the following points:

1) A remapped car always works at higher than stock limit levels even if its been driven by a non-aggressive driver.
2) What percentage of people are we looking at who get their cars remapped(for performance)/chiptuned/pedaltuned but arent aggressive drivers?

I read somewhere that even a product like a pedal tune modifies driver's wish map, like a remap. So the above equation stands corrected.

Logically power gain is not possible. But I think it can help in 0-100, in gear acceleration timing. On stock settings, the voltage rise graph is linear. But on pedal tune it's not linear, but it meets the stock graph at the end. So this doesn't lead to any dead zone on the pedal.

I didn't find much improvement in Eco mode. Maybe I did not spend too much time there. Been only in Sports and RACE mode. Will drive in ECO mode too and report back. The problem is I just don't feel like using that mode (call me narrow minded if you wish...LOL!)

In gear acceleration and 0-100 timing can be definitely improved with the paidal tune (pun intended akin to Jaggu) as the car feels blisteringly fast

Besides the above point, ToT quoted a ridiculously high price of 34K and I have used the tuning box in the past and I can't say I have any complaints and its been enjoyable to use them with no effects to the engine over a 60,000kms usage

I was ready for a remap and Pete acted little high-handed (lackluster response to my enquiry) and their discounted offer was also taken off so I decided to go back to the TB route

The deadly combination of TB and PT will be installed over the weekend and tested on ORR by me and Anurag and we'll come back with all reports of our tests

What is the point of these equations? Keeping the driver constant above equations don't make any sense

Remember a normal driver will most likely not go for any modifications such as the PT & TB

How? More often it eases load on engine with more fuelling et all and reduces stress, compared to an engine which is tightly tuned for emissions etc

2) What percentage of people are we looking at who get their cars remapped(for performance)/chiptuned/pedaltuned but arent aggressive drivers?

Now why are we doing statistics? and what makes it not applicable to Paidal tune?

I doubt it changes anything more than throttle input.

This is not for you, was explaining matters to someone else my friend. :P

What's a TB? Tuning box? I wasn't talking of tuning box, I am talking of a remap. A tuning box is a more sophisticated cheat device. It takes value from 2 sensors and changes that coming out of the ECU.

A remap is changing the map stored inside the ECU which can alter throttle.

A tuning box is a box that changes values going into or out of the ECU thereby fooling the ECU and making it compensate.

A pedal tune just changes the throttle position value going into the ECU and makes the ECU behave accordingly.

[Dr.Naren]

Be it normal or aggressive driver, pedal tune box can't put any extra stress on the engine. Logically the box can't increase the power and all it does is cut the lag and make the throttle super crisp. I am still little skeptical and I would buy the box only if I am happy with 0-100 / in gear acceleration.

With remap, you increase the fuelling above stock across the revv band. There is more power/torque and obviously more stress on the engine. I am not saying remap would kill the engine, manufacturers do keep a good safety margin.

There's something called drivers wish map. Making changes here could result in better throttle response. But I doubt it would be as effective as pedal tune. Its not an easy process with remap. There are other limiter maps too. All need to be tweaked and made to work in harmony.

Also, Remap vs Pedal Tune is not even a topic to debate. Both work differently. Pedal Tune works well even in remapped cars. Frank is running his GT TSI with remap, pedal tune and DSG T Box.

Yes, with a remap you would feel that engine is less stressful. But what we feel is not the same what engine would "feel". Remap = more fuel = driver happy and would feel engine doesn't struggle. But more fuel = more EGT (in a diesel) = Engine, turbo charger wear and tear level increase .We can't feel that

Also how does remap make power?? Yes, you tweak many maps. Ultimately it's the injectors and turbo charger which is put under stress ( say more than stock). If you change fuel rail pressure map.,even CRDI high pressure pump is put under more stress.

Not true. You are now driving with more throttle than what is needed. So now normal acceleration is rapid. This will put more load on the clutch and also inject more fuel thereby it's like an aggressive driver driving all times.

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

What I was trying to say is that "Pedal tune box cannot inject more fuel". I am taking about the Max IQ(Injected Quantity. Also the ECU looks at accelerator pedal position and requests certain amount of fuel. Pedal tune box should work within the safety limits set in ECU maps. This is the reason why at full throttle, pedal tune box effect is same as stock.

Some users have reported better FE too. Let's wait for further updates from Avinash. He should have been exploiting the box fully

Who said it will inject more fuel? There's no connection to fuelling so there's no way to inject more fuel than what the ECU is mapped to.

But it will always run higher throttle than stock. This is what increases wear. The car will be at higher throttle than the stock at all times. You need to then compensate that. Plus it will mean more braking.

Point is not engine wear and tear alone but overall mechanical wear and tear to clutch, brakes and other components.

[blackbandit]

Dr. Naren. I guess you misunderstood Vid6639. What he's trying to explain seems to be the wear and tear generally caused by employing aggressive driving which would happen even without pedaltune when vehicles are driven pedal to the floor continuously. He's not implying any additional stress or load. What he's trying to say is that pedal tune would translate even a normal driver to an aggressive one.

I had mentioned in my post that Pedal tune box won't put extra stress on the engine Since the fuelling is within safety limits set by ECU, pedal tune can't do anything here.

Regarding mechanical wear of other parts, I would partially agree.

Be it a normal or aggressive driver, he would expect something by pressing the pedal. Say the driver wants 60 percent throttle effect, he will get it by pushing the pedal harder without pedal box while the same effect he would get early by pressing the pedal lesser with the box. With or without the box, the driver is going to get that throttle response. Once the driver is used to pedal tune box, he will adjust his driving style and obviously use the pedal lesser. We can't say that Pedal box can make a driver aggressive.
