Oettinger Turbo Diesel Remap

[sparky]

Have just got a price of $2400 to remap the ECU in my coming V6 Turbo Diesel by Oettinger--has anyone done it and if so was it worth it?Rgds Sparky

[Treg2]

Would not recommend remapping the factory ECU, it could screw up the ability to report error codes correctly.

A better way would be to used the DP Chip plug and play solution from AWD Technologies. If you are getting the V6 Tdi the DP31 literally installs in 5 minutes and makes a remarkable difference to the of the line performance.

I would recommend you visit this web site and research the product for your self.

where did you hear this?

[bobzed57]

Not to mention that the DP Chip is about $1300

[sparky]

Offered by Volkspower via Ottinger download..apparently okd by my local dealer--see Ottinger site re the results...191KW and 550nm--the DP loom as I understand it generally increases fuel pressure ...understand the Ottinger and Steinbauer systems change a number of variables--hence my question who has tried any?

That's cobblers, none of the fault reporting is affected.

Plug in chipping isn't as sophisticated as flashing the std ECU. It modifies signals between the ECU and fuel system rather than using correctly written software in the first place.

Chipping or Remapping is governed by what type of engine configuration and what modifications you have performed.

I have just traded an MY03 Subaru WRX with cold air induction, exhaust, fuel pump and injector modifications which required a ECU remap.

My newly purchased Touareg has none and most likely will never have any modifications to the engine so remapping the ECU seems unnecessary particularly when Volkswagen Australia most likely would NOT warranty such a modification.

My own personal decision was to use the DP plug in option mainly because a large number of diesel transport vehicles are using it successfully. It is undetectable by the dealers software if I choose to leave it connected, but if I do want to remove it I can pull it out in 5 minutes and revert the vehicle back to factory spec.

As for the error code comment I was speaking from experience, but I must admit it was with my WRX which is a whole different animal to the diesel powered Touareg.

I suppose the bottom line is do what ever you feel comfortable with, perform due diligence to confirm who is going to warranty your engine if something goes wrong or be prepared to cope the cost yourself.

Chip it or not?
If you have a chip installed Vag-com will find out, so I thing the factory VAS diagnostic tool will find it even faster. And if you reprogram it, it will be recorded similarly like in this attached picture.

I personally like original things - not modified.
Put yourself in the manufacturer shoes and imagine that somebody bought your car which you designed and produced. He modified it to get more power out of it with out proper testing and when it is broken down he even demands repair it under the warranty.
Would you repair it?
I wouldn’t.
The manufacturers warranty is the best warranty you can have. Don’t fell for warranty from the chip manufacturer. Wait till the warranty is over and then chip it.

Just to clear up some of the "myth's" in this thread:

A properly tuned ECU reflash (like Oettingers) is exactly that - a fully retuned ECU, changing requested & actual boost, fuel delivery, timing / pulse, load signals (yes -- the load signals that feed directly to the TCU & also take the feedback from the TCU - which protect your transmission). It also transmitss all sensors in their exact, original form, fault codes & all. if your fuel pressure sender gets a fault - its recorded!

A "tuning box" of any brand can not do all this - pure & simple. We sold "tuning boxes" from Germany for many years (and the German ones were about 2k) - We have seen some sold here in Australia in volumes that are made in Indonesia for about a total cost of $75 and then sold on for $1000 to $1500. Tuning boxes were good in the older style motors, but would you use them on a newer style motor? - If you know how your EDC 15 & EDC 16 ECU works in your later VW, you will know how it records & logs data. Bump up the fuel pressure & it records it - purely & simply.

There was a well known case of a Touareg V10 TDI in Brisbane that was fitted with "Tuning Boxes" - the car developed fuel system leaks (lots of them) and was taken in for "warranty" - Of course it was denied and upon investigation it was found that the owner had removed the tuning boxes as advised by the "company" that sold them to him.

Big risk on an expensive new TDI motor.

Of course we sell Oettinger so we know it's effects - and also what written warranty is offered from them (see the website) - and we can also arrange for Oettinger to be installed in your new Touareg via select dealers around the country - complete with 3 year written engine / drivetrain. Feel free to call me if you need any more details. We are responsible for tuning well over 500 VW & Audi diesels in the past few years (07 3392 2980)

P.S. - MR T5 is correct -

Modifications of any sort - Can effect warranty.

The biggest issue & responsible for the biggest number of claims is window tinting - Most people think window tinting is harmless - but often an untrained apprentice will have the job of dismantling your new cars door trims to get access to the windows - Broken clips, rattles, damaged door handle connectors etc.

So tinting your windows can void the warranty on the doors of your car (and has!)

[OilBurna]

well said Guy H wise words, I know which one I woudl be going for... there was also a whole thread on 4 x 4 monthly forum about all the different chips / ecu reflashes etc worth reading.

Let me tell you something. If I go to the dealer to replace broken clip and warranty would be voided because of the window tint:
To replace that broken clip in the door trim the worst thing can happen I pay for the clip and an hour of the labor and I can pay for it with the smile on my face.

But if the dealer would be saying to you after your Touareg was brought to the workshop on the tow truck: Mr. Guy_H you modified EDC module which caused damage to the engine and it will cost you $15,000 and it will take a month because the parts we need have to come from Germany. I want to see the same smile on your face.j:

P.S
You see some things are just not worth it.
It is very competitive market and manufacturers are tuning their engines for more and more power all the time.
Maybe you should give them your number; because they might be interested in your power chips and performance modifications that you are selling in hundreds.;)

What inflammatory statement::?
The tinted window - broken clip voided warranty or the modified EDC broken engine voided warranty.
That's raising awareness of potential danger that you may lose a new car warranty which you paid for. And doing more harm than good. Leaving the legal issue alone.
I know that on this forum is many people who modify their cars and maybe they see it from different point of view.

I don’t like when somebody is using my post and try to make an idiot from me

As the one who started this discussion,its interesting that VW themselves have just remapped the 2008 TDI from week 45 production in 2007 from 165kw and 500nm to 176kw and 550nm....I also agree with Guy H that from my research the O system is the most appropriate way of adjusting performance..it is not warranted by VW but understand they will at least fund it in their finance packages so I am told!Rgds Sparky
Also understand that in the normal course the IS NOT visable during Service!

You are right, but with some minor engine mechanical changes.
I have Transporter T5 with R5 engine and the same engine in The Dakar Race Touareg is producing some 218kW that's 90kW more than the standard R5 engine. And without knowing what other changes were done to achieve such a huge power increase (leave alone affect on the engine durability) I wouldn't chip mine.

Companies who are selling the power chips will not tell you that in order to minimize negative affect on the engine and other components life you have to do some other mechanical changes to your engine to safely get more power from it. That would discourage many potential buyers. And since some modern engines can tolerate some power increase they will get away with it.

It is something like that.
The engines are build for specific output and due to the tolerances in manufacturing process some engines would produce lets say 20% less power, so 1/3 would be less, 1/3 would be spot on and 1/3 would be able to safely get more power output than original specs, so the adjustments are made in ECU (EDC) software at final stages to accommodate that inaccuracy.
So, this is why it is a blind shot when you install the power chip.
Now for myself, I’m closing on this topic.

[gldgti]

let me offer some engineering knowledge to the debate so that we might make more sense of the question of reliability vs performance vs chip ugrades vs other engine modifications, and how they all fit together.

starting with the basics: an engine produces torque. when this torque is multiplied by the engines angular velocity (or rpm) the figure becomes power, measured in watts (which is Joules-per-second).

so if your Toureg produces 550Nm at 1800rpm, then you can find out that the power at 1800 rpm is

P = T*w
= 550 * (1800*2*pi/60)
= 550 * 188.5
= 103.7 kW

and ofcourse, the equation works backwards - if the dakar R5 engine makes 218kW at around say 4500 rpm, then the torque output is

T = P/w
= 218,000/(4500*2*pi/60)
= 218,000/471.4
= 462Nm

now that we all understand that, we can stop talking about power and concentrate on torque, ok? good.

if you want a diesel engine to produce torque, you need 3 things. air, fuel and compression. compression is fixed. so all you can do is play with air and fuel.

if you have a normally aspirated diesel, it is very hard to make a lot of torque, because you have trouble getting much air into the cylinder. thus, normally aspirated diesels tend to be low power units - like the mk1 1500cc engine.

however, by utilising a turbocharger, we are able to force in more air. this allows us to add more fuel, and thus we see an increase in torque output.

now consider that when you do all of this compressing, burning, expanding, your highly efficent diesel engine uses about 40% of the fuel energy to make torque. the rest is turned into HEAT.

there are 2 main exits for this heat - 1 is though the cooling system, and the other is the exhaust.

when an engine is designed and engineered to go in a car, so is the cooling system. all things work in harmony to produce a net life expectancy for the engine, for which the manufacturer bases their economics, and thus warranties.

NEW DIRECTION - if you want to increase the output of any diesel engine, all you need to do is increase the amount of air and fuel you can squease into each cylinder. so if you run higher boost, you add more fuel, and you produce more torque.

you also produce more heat, and since the cooling system will not remove much more than it already does, the rest of the heat must go out f the exahaust system.

ASK ANY DIESEL ENTHUSIAST about performance tuning a diesel and the precautions required, and there is ONE thing at the top of the list - EXHAUST GAS TEMPERATURE.

so what does this mean? when you increase the torque output of your diesel engine, without changing anything else the exhaust gas temperature increases. ALWAYS.

now, it depends how much overdesign in the cooling system and the old exhaust system there is, and how restrictive your turbocharger setup is as to what power increase will result in what change in EGT - however, the more air and fuel you put into the engine, the higher the EGT's, UNTIL one day driving up a big hill with a load on, your piston melts and wont slide in the cylinder anymore, or your turbine gets so hot it breaks apart at 200,000rpm and causes you a big headache.

so the logic is that if you want to increase the torque output, it should be done with EGT's in mind, and hence you need to do things to remove the extra heat produced by the engine.

firstly, your super silent stock exhaust is the most heat restrictive piece of equipment on your car. i'll bet a lot of money that the R5 dakar treg would have a mighty big exhaust with NO mufflers at all.

secondly, if you are running your turbocharger faster and harder to get greater boost pressures, then the temperature of the inlet air becomes REALLY high, REALLY fast. which is why any performance diesel needs an intercooler - and the more power you want, the bigger the intercooler you need. at just 12psi boost, inlet air of 25deg c will be typically 135 deg c once compressed.

most new tdi's with VNT turbochargers will hit 30-35psi at times, depending on the ecu mappings.

finally, your stock turbocharger has an efficiency range of rpm against pressure ratio. small VNT's like are fitted to new TDI's are typically designed to hit high boost pressures for short periods of time - like hard city traffic acceleration. but the longer your tiny turbo is at super high rpm, the hotter it gets, as well as it prolonged use at high rpm. already it is a given fact that VNT's seem to wear out faster than the wastegated turbochargers of old, because they rev so much faster, the bearings simply wear out.

so back to torque and power - if get an ecu flash or DP chip box or whatever, that increases your max torque right through the rpm range, including a big increase in max power (torque at high rev's) then you can expect that your turbocharger is working super hard to give you the air required at those high rpm.

Now ofcourse, Oettinger know about all this. they will have factored it in already, but the fact remains that if you use all that peak power, you will be shortening the life of something - probably your turbocharger.

in my experience, people want something for nothing with new cars - "what chip should i get that wont void the warranty?" or "what chip gives me the safest power increase?"

the simple answer is none of them - unless you are willing to put a less restrictive exhaust, a larger intercooler, a bigger radiator, larger turbocharger's etc etc etc. its all relative. a 10% increase may not make any real difference to the life of the engine, but a 20 percent increase will definately have more of an effect and so on.

in turning my 55kw 1.9TD into something which now would be pushing 75kW, i have already had to take this into account - fitting an intercooler has already happened. but i know that its not safe for me to increase the fuelling much more, or increase the boost much more until i upgrade the exhaust aswell, because if i dont, i'll end up without a car to drive at all.

the bottom line is this - if you want to increase the output of your diesel by any really noticable amount without causing yourself future headaches, a chip wont do it all for you. you will need to sacrifice something else - quietness, comfort, money.... something in order to allow your engine to remove the extra heat.

and if you wanto to go all out and make your v10 treg produce 2000Nm and 500kW, then i i reckon you might want ot think about selling the kids... :-)

[Transporter]

Ok, let’s not forget that when you build the engine one has to calculate how strong the components have to be. And because weight is an important factor the engine has to be as light as possible.
Of course new materials and science will help with this, but nobody will make the components stronger than they have to be and waste money in case one day somebody wants more power from that engine and decide to install the power chip. Instead when you buy the car you can choose the model with the stronger engine which is a much safer choice since the suspension and the brakes will match the power of that engine (you see it is safety aspect as well).

But the bottom line is this. If the engine is built for max power 128kW and 400Nm torque plus some safety buffer. It means you cannot increase the torque over maximum torque allowed, if you do, something will fail.

i have ignored this factor due to the simple fact that vw diesels have always been much stronger than required, and that any trouble caused by making more torque from a chip upgrade will come from heat long before overstressing the engine internals becomes an issue.

I agree, but also consider the torque the transmission can handle, isn't the 5 spd in the t5 the same as the v10 :? In those circumstances I can't see a problem with increasing the torque and hp in a t5

[T Rex]

Hope you don't mind a new chum joining in.

Having test driven the 165kw/500nm V6 lTDI ast week I could only describe the power as ample and the torque as awsome. And yes, when mine arrives it will have the 176kw/550nm but I can't help thinking that the engine in the car I drove was great and more than up to the job and if fiddling with the ECU affects reliability and/or the warranty it is a rather pointless exercise.

I think you'll find most of the people using of considering this chip are driving the R5 with the smaller engine. I to test drove both, and while the R5 responded to the throttle as I expected, the v6 exceeded my expectations. If I had a 2nd hand R5 out of warranty, I'd consider the chip

Hi David
I agree. I only made the comment because the original post referred to a new V6 TDi. Many moons ago I bought a brand new 3.9 Range Rover and as soon as the warranty was up did a 4.6 conversion which was great for the following 15 years. Mind you. both those engines were asthmatic compared to the modern TDi breed.

Just to put another spin on this thread, whether you chip or remap is totally up to each individual but one thing that does concerns me is the quality of some diesel fuels.

With the high price of fuel today the practise of blending fuel could be tempting to unscrupulous retailers wanting to make a better profit margin.

Dodgy fuel will kill an engine far quicker than modifications and the manufacture has no responsibility to repair anything.

Pity there's no black list on line that we could identify these outlets.

Agree with this one. Just returned from a trip away to country NSW and fuelled up at the only servo in the town. I normally use BP diesel (local to me and I have a BP card to use) this servo was an independent but a well known one (not that I remember which one it was). There was a notable difference in the response to my vehicle. Fuel economy dropped by about 1.5ltrs per 100km and I would guess 0-100 times a fraction of a second out. And to top this off 5 cents per litre above the Sydney diesel price.
I have since run a tank of my trusted BP diesel and the vehicle is happy now.

Yes be careful on what fuel you use.

Yes that's 100% truth, bad fuel will kill engine faster than chip but chiped(modified) engine using bad fuel would be worst of than stock engine and would be killed even faster.:)

Difference between R5 engine in Touareg and The Race Touareg2.

Touareg R5 engine:
Power: 128kW
Torque: 400Nm
Cylinder head with 2 Valves per cylinder.
Turbocharger with intercooler.

Race Touareg2 with R5engine:
Power: 209kW approximately
Torque: over 600Nm
Cylinder head with 4 Valves per cylinder which allows better gas flow rate.
Two stage supercharged system with turbochargers and intercooler installed longitudinally behind front suspension.
Engine also has a better cooling.

Remap is better than chip.
Simple things to consider.
Stability control is not just nipping the brakes - stability control is also about reducing engine power at the correct time.
Tuning boxes are adding power and torque that the stability control system (and ECU) knows nothing about. Thus you have no or at best uncalibrated stability control. Day to day no issue - but if you need stability control then you will have issues aka loss of control (I speak from experience here).
Tuning boxes were originally developed for prime movers (big trucks) and do work very well. Similarly they work well for older diesel vehicles with no stability control.
Remap is the only safe option for the Treg or any modern vehicle with stability control.
