Engine remaps

The Guvnor

Just curious as to the potential benefits of having this done?

I'm not to fussed about the performance aspect although the standard would be to take a 130bhp passat to 163 and a 225 Touareg to 270.

Was simply curious as to the increased fuel efficiency? I've been told for example to expect say 3-4 mpg on the touareg or going from 26-30 etc when on motorways.

Is this realistic or a bit optimistic or even pessimistic?

I was warned against it by a couple of mechanics. They ain't good for the turbo.

Thanks Pappy!
Net result could fcuk up the turbo, I assume?

I made this point on another thread recently, a lot of mechanics are scared of ecu mapping because they don't understand what it is.

If you have a car mapped then in turn drive the ring out of it because it's faster then maybe you might damage components but generally speaking they are fine for the car.

OP you will see slightly increased fuel economy if your driving style stays the same, depending on the car you will see increased mid range torque and power

It all depends on what mechanic you ask. In my experience, mechanics that don't know much about remapping will advise against. those that know a fair bit about them will advise that the car can handle it..as long as it gets a decent map and you don't drive it like you stole it I have ben led to believe there is no problem.

edit: was beaten to it!

Plus cars are delibrately held back by the OEM because they know that not everyone will service the car when they should, because they know not everyone wants a performance car, because they know people will cheap out and buy the oil thats 5 euro a litre cheaper...

Cars to most people are a way to get from A to B. To someone like the OP they obviously have an interest in cars and are more likely to maintain them at proper intervals, use the best oil etc so things like that are safe.

If you do anything to a car like small bolt on mods you should get the car mapped to make use of these.

OP I looked into it last week.

It seems most likely with a VAG TDI the only negative impact you will have is on clutch life if all mechanics are in full working order.

I have sided against getting it done in my case due to the high mileage on the car and the fact I am thinking of changing in 6 months time anyway. I just don't want an unnecessary expense like a clutch change before the car goes. Then again I may end up keeping it longer I just don't know.

The mechanic said it should be fine as long as you get it done correctly and don't try and tune it to too high an out put without upgrading other parts to handle the power.

Thanks Lads.

I was looking at a CO in Ballymena Auto-Tune - £200 plus VAT.

It was really just a thought to perhaps get the mpg on a thirsty touareg from 26 to 30 for motorway driving at your typical 60-80mph.

The Touareg has a 22 gallon or 100 litre tank and an extra 4 mpg would be noticeable.

Potentially increasing the range from the 550 miles to about 650 miles.

The gent in Auto-Tune said they are cautious and would increase the bhp by 30-40 in most cases which does not seem too much.

I presume something like a 3 litre Touareg would be an ideal car to have something like this done in terms of seeing some benefits.

As I said - this thing is a truck - it'll never be quick and will never be driven enthusiastically - I did this in the UK and the mpg was painful - 8-9-10mpg!:D

The Guvnor

The clutch makes sense.
The Touareg has 32k on it atm and would suffer mostly motorway driving which should help.

Gary ITR

Where are you based? I work with Joe Power @ TDR and his rep speaks for itself, just take a look at vagdrivers, I can get you a price if you like?

they prob would do a good job as they have a good rep on some of the northen forums but my best mate has had an absolute horror story with those guys over a £200 map.

Wont go into detail as a legal case is pending, but if anything goes wrong or even it just needs tweaked it would be better to get this done closed to home in my opinion!

What about so called low pressure turbos? E.g. Saab 9-3 2 litre, petrol, it's marked as 1.8t (150hp). From what I know, there is exactly same engine with same turbo (marked as 2.0t) but factory software squeeze 200hp out of it.

I theory, given the remap was done properly, there shouldn't be any major risks for such?

The Guvnor

Thanks again lads!

Onkle a price would be great.

Has Joe a website if not will check out the feedback at Vagdrivers but if you vouch for him that's good enough for me mate.

I got my BMW 318d remapped last week and I am very happy with the results so far. Gone from 143bhp upto 180bhp. More importantly though the torque has also increased making the car more responsive from take off and through the lower gears. I'm not a traffic light grand prix merchant but I know that I have enough power to overtake quickly and safely if needed.

What kind of car is it op? And which variant? I'll get you the price tomorrow

http://www.autoremap.ie/ is another site.
They actually have a forum on http://www.bmw-driver.net/forum/ and can tell you what you can expect to get from a remap etc.
I'm thinking of doing it to my BMW 520D....it will increase the hp from 163 to approx 190 but more importantly the torgue so better acceleration in 2nd gear and higher etc.
You'll also get better fuel economy depending on how you drive it.
However you need to be aware that it could affect your warranty and you must tell your insurance company.



apologies..I didn't see Onkle's post..

The Guvnor

Thanks lads.

Onkle - 3 litre v6 tdi touareg - 2006 October reg - se spec fwiw.

Thanks.

It's the fuel economy I am after but having said that a bit more torque is always handy.:)

Hey Bazz

Interesting that you got the remap. Just wondering if it really makes a huge difference? Would it affect the MPG as well as BHP and torque? Are the people around Ireland with a good reputation for remapping? Cheers
