What neat fuel ? It has been atomised by a fuel injector and at least partially combusted.

Unlike your "rocket science" ?

I got a puncture today, can I sue the mapper as he made me drive further and faster than I would ever dare to in a standard car ? ? ?

Well, I'm as confused about the claims here as all the major manufacturers are .... they have dreamed of the day they can produce a 550 BHP car which returns 30 mpg .... with absolutely no downside whatsoever!!

Even the cost of the re-map doesn't come into a new build ..... so, it's win, win, win, win!!

What some are saying here is, take an Impreza Turbo ... price, what? let's say £20,000 ... get a hobbyist to re-map the car for £650 ... and, 30 minutes later **BANG** you have a fire breathing monster capable of amazing feats.

Hell, why stop with the Impreza - why not ask NASA if you can re-map their space shuttle? ....... I mean, for little cost humans will be in and out of a black hole and stop time, returning 2 minutes later having burnt just a thimble full of rocket fuel

Come on, you can tell Uncle Peter ..... what's the trade off?

Pete, you remind me of the 'know it all' **** that used to sit behind me in class when I was at high school. Day after day he would disagree with the teachers and 'try' and show his superiority. Thing is EVERYONE knew he just liked to argue and disagree so he was told to sit outside of every class from then forward, at his own little desk in his own little world.

All of the professional mappers has answered all of your questions and have taken the time to explain to you in great detail about remaps. Take the information on board and stop your childish bickering.

You said you were an engineer - please explain what expertise you have Pete because for the life of me I see no evidence of you having any understanding of engines or combustion and a complete lack of ability to learn when presented with clear information and facts. I thought that was what engineers excel at - obviously I was wrong.

You have also had several offers to prove it to you in person yet you turn these down or ignore and still bleet on about how it is not possible to produce more power with less fuel. It is not only possible but it is fact and is easily proven if you will open your eyes.

I understand you are just trying to wind people up - that's fine if you have nothing left in your life apart from trying that. I am, however, sure that no-one here is getting wound up so please try harder.

Far from winding anyone up, I am asking what the downsides of producing 550 BHP and 30 mpg out of an Impreza with a re-map are?

The only downside I have been offered is the cost of the re-map .... this cost would not stop Subaru doing the same (as the different map is no extra cost to them).

If a re-map had no downsides, only upsides, then we all know that the car manufacturers would be producing 550 BHP and 30 mpg vehicles ... why wouldn't they?

Imagine what a re-map could do if applied to, say, a Diesel FORD Fiesta ECOnetic 1.6 Duratorq TDCi 90ps DPF? which would normally return 76.3 mpg at 90ps.

I have chosen a Ford just incase the Subaru Mappers really don't have a clue as has been said here. I assume that the Ford Mappers may have a better idea?

Subject that car to a re-map and one could reasonably expect 95 mpg couple to a power of 180 ps ..... what stops Ford doing that?

Driving fast doesn't wear brake pads out!

Braking does!!

I was taught to drive with the idea that I had a raw egg under each pedal, I honestly rarely brake .... reading the road ahead with skill will make your brakes last a good while.

coasting down when approaching a roundabout or junction is good roadcraft, but an extremely boring way to drive, i sometimes drive my boring workvan boringly, coasting down etc, but i drive my scoob with a little bit more excitement, sure i'll clean the brakedust off more, and replace my pads more often, but hey, life needs a little excitement.

My superb roadcraft is inbuilt, I'm afraid, .... it's very difficult for me to drive like a **** in all honesty.

I get a lot of pleasure driving my car properly ... I estimate that my driving style and experience is equivalent to an extra 50 BHP for you kiddies?

no doubt when i'm really old, and my eyesight is not so good, and my reflexes have seen better days, i too will embrace 'roadcraft' and reverse into shopping trolleys, and drive with a hat on, hell, i may even put some cushions on my parcel shelf and a box on kleenex in between them.

And you would have every right to do that ..... it's a great way to operate in all honesty.

You kiddies get all hot and bothered racing around at speed, but getting nowhere fast

You get to the back of the next queue 10 seconds before I do ...

Well he is not called the Drivel-meister of SN for no good reason.
65 K out of a set of break pads and the guy owns a Subaru - really tells you all you need to know, doesn't it?

Come on, you can tell Uncle Peter ..... what's the trade off?
You can't turn a WRX into a 550bhp monster with just a remap. You will need to spend thousands of £s on uprating many other components from turbos to brakes etc. A Subaru that expensive just would not sell in huge numbers. How many T25s do you see day to day?

You answered your own question earlier as to the downsides. That is the increased wear on most of the moving parts. We all accept that we may have to change parts a little sooner, but it is a price worth paying for the extra drivability and performance.

The standard Subaru map has to conform to strict noise and emissions regulations which are tested at specific rev points. A remap will not be restricted by this. I'm sure it is legal, but possibly morally questionable.

Some would consider the inability to spell as a greater crime ....

But maybe that's all in the past?

I really don't think that you SSU are in a position to criticise others peoples spelling mistakes do you?

You have great pleasure in pointing out spelling mistakes in other members posts but when I pointed out 3 spelling mistakes by yourself in more or less consecutive posts you ignored them.

Are you so far up your own ar$e that you can't even acknowledge your own errors but try and embarass and humiliate other members whenever possible.
You cannot win your argument end of story, I just wish you would accept what everyone else on this thread accepted a long time ago - that you are totally clueless and are desperately trying to 'mix it' with some of the best people in the mapping business and you have just made yourself look like an idiot.

Let's look at the facts shall we?

1. A re-map can increase the mpg by up to 2 mpg - but only on cruise/light throttle.

2. If the power is used then the mpg drops to the floor - into single figures.

3. A re-map carries no warranty whatsoever, if your engine blows you are on your own.

4. A re-map will not result in any improvement unless other mods are carried out.

5. Due to 4. above - it is impossible to answer the OP accurately on whether mapping improves mpg .... I suspect that it does not, on it's own, improve mpg.

6. A re-map will shorten the life of the components on your car, of course all most Mods to increase power will .... but a re-map most certainly will.

7. Car Manufacturers employ top mappers, skilled engineers, they know their business, they know their subject .... I will let them decide what the best state of tune is for my car.

8. Yes, sometimes these Manufacturer mappers get it wrong - it's human nature to make an error ... their errors are backed up by a fantastic warranty - things will be rectified.

9. In the very same way that re-mappers can get it wrong ... with disastrous results. Disastrous because you are on your own, no rebuilt engine, no repayment of expenses, no warranty to fall back on.

I don't mind anyone tuning their cars, getting excited in their garages about the latest KockLink design or generally enjoying their hobby .... I think it's great!

What I don't agree with, and feel the need to question, areme of the myths and outlandish suggestions posted here ...... and there is such a load of tosh spoken that the non-engineer can be misled and ruin their engine.

1. No. The average could increase by 2 mpg. Not many of us drive all the time at cruise/light throttle (except you), but still notice better mpg.

2. A standard car's mpg will be in single figures at full power. A remapped car's mpg will not be massively worse.

3. That's why most people wait until the manufacturer warranty has expired. You have no warranty on a 4 year old car, mapped or standard.

4. No. The PPP is basically a remap and the removal of a small cat. This gives an extra 40bhp. I don't think this is all due to the cat removal. Put this cat back and I'd bet you'd still get 30bhp over standard from the remap alone.

5. I'd bet a remap alone would improve mpg, but wouldn't be worth the cost. A 2mpg improvement would take around 50000 miles to pay for itself.

6. Most of us own Scoobs for the pleasure they give us. If you can get supercar performance from one without spending supercar money, then why not? It will still be more reliable than your typical Italian exotica. If you want a sensible car, you buy a Toyota Corolla.

7. If you are happy with your car, fine. We are happy, too.

8. See 3.

9. I would hope that if your engine blew up on the way home from mapping, then there would be some comeback from the mapper. It may involve court action, maybe. Would be interested if anyone has ever felt their engine blew up as a result of a poor map.

10. Can't believe I'm bothering to reply.

I waited 13 months before i finally had my car remapped 2 weeks ago. I am not taking any sides on this debate, but do you think i got the remap done to worry about how many mpg its going to give me. NO NO NO .I got it done so the car can hit 125 mph in 4th and if it drinks fuel like an alcoholic at a free bar the so be it.Also if the engine goes bang ,then its me driving it at the speed i choose to ,so why would i want to go and see the mapper
I also have a 2001 honda civic 1.4 i that returned 88.4 miles on the £10.00(8.76 ltrs) of fuel i put in this morning which is the car i use for work - i can not believe people can buy a subaru and then worry about mpg - wtf

Oh good, SSU has posted up the same repeated claptrap that he has before.

I first had the 'pleasure' of reading his posts when he was stating that he didn't feel it fair that a garage was or had charged him for a diagnostics check, as I remember he was in a minority of one there as well.

I suppose that ignorance really must be bliss...
