Okay, I'll own up to being a woman. And a numpty when it comes to engines.

I've seen various threads on here referring to 'remaps' but have no idea what they are. I suspect it has something to do with changing the settings that run the engine, so that it performs more efficiently - but I'm not sure.

So - please please, can someone write a beginners guide to remapping for me. Thank you.

[I've googled but don't understand most of the information provided]

just get in touch with Martin at pendle performance and he will tell you all you need to know,and if you have done you wont be disappointed,its still the best money i`ve spent on my bus in nearly 2 years.*<:)>*<:)>

I'm afraid that remaps are 'mens business.' We'll promise not to ask about 20 denier stockings, low calorie salad dressings, and how to remove cheese stains from tablecloths, if you promise never to ask about engine tuning again.

But then i've seen a couple of threads where things have gone wrong after a remap.

What kinds of settings get changed? Does it 'soup up' the engine? And is a remap legal? Does it put undue strain on an engine that's not designed to run in the remapped way? Does the engine wear out more quickly if it is remapped?

[See what I mean ? - a COMPLETE numpty!!]

you're no numpty. They are all valid questions. I am sure I don't have to remind you to garner as many opinions as possible and then decide the answer for yourself :)
If you search this forum and read all the relevant threads there's a start.
The answers you won't find will be implied. Nobody tells you that tyre life will suffer, 25% more torque tells you this.
Enjoy you're xmas reading.

Your far from being a numpty it's a very good question. Hope you get sound advice i did but i'm not going to mention the company i used. Theres loads out there speak to a couple and you will get a feel for them and if they know what their talking about. Merry Christmas & Happy Hunting. *<:)>

It could become an interesting thread, this. I'm looking forward to some replies.

Changing the algorithms inside the chips, aka remapping, is re-programming the computers that run the engine.
It can be done by anyone with a laptop and a connection lead.**
VW boffins decided on the best all-round settings for performance and economy, to suit everyone buying a T4... but you can delete all that and instead choose your own settings. Most, but not all, go for all-out performance and hang the economy.
Some suggest that you can save fuel because having more power means driving it less hard.
But most remaps just chuck as much fuel into an engine as possible in the hope it will get made into more power. Look at the black smoke of unburned fuel coming out of the exhaust as evidence. I cant see that idea averaging out as any real fuel economy over a tankfull?
My brothers T5 didnt - it drank fuel (and kept on defaulting to limp mode) when he had a cheap remap done.

** Lots of people own a laptop and a VW connection lead.
Most of them read forums and web pages.
Some of them sound like they know all about it, many will know more about it than me and you.
They might have saved, or found, chip settings that suited someone elses T4 engine once upon a time.
They want to overwrite your chips with those settings, as long as you part with £150 OR SO?
I wouldnt let any of them anywhere near the carburettors on my beach buggy, (new engine £200?) let alone mess with my modern finely tuned T4 turbocharged engine (replacement £1000+?)
Look very carefully at anyone who wants to mess with your engine, and in my opinion if they do not possess a rolling road Dyno, a well equiped workshop and are fully insured as engine tuners do not even pop the bonnet catch.
Too much money at stake.

Thank you for a very informative post, which had made it much easier for me to understand. I wasn't planning on remapping my engine, but had read so many threads about it that I was beginning to think it was something that should be done. You have reassured me that it doesn't, and that it is actually risky to do so. Besides, my insurance is tolerant of any cosmetic changes made, but not of changes which affect the performance of the engine.

Well wrote and I totally agree.

If you read one of the neighbouring posts you might be excused for thinking a remap is just and excuse to throw toys out of the pram and get involved in a futile game of 'my dad is bigger than your dad' :rolleyes:

Dear Impis,

I too am a numpty when it comes to remapping and I am a bloke.

Sometimes I wonder why don't VW, and all the rest, bung out the increased BHP in the first place with the claimed economy savings.

It may be that VW have an eye on, or are constrained by, EU Emission Regulations or by Insurance companies who don't want too-lively vans on the road. A vehicle with commercial underpinnings and 100 mph potential could be a handful in the wrong hands, (probably mine).

What is going on with this forum? Has it lost it's sense of humor? Just because it's his first post it doesn't mean it wasn't meant tongue in cheek :*

Too many serious people taking comments and life to serious. lighten up it's Christmas.

Impis, a re-map can be very practical if done correctly and is not always used for performance as some might have you think. I can be a very good way of gaining a little extra power for towing, hills or just for general day to day driving which can of course add a few extra miles too those very expensive fill ups :(

I know GHE tuning has his BMW re-mapped for economy and now sees well over 60mpg, my best advice would be do some homework and have a read of some of the threads on here and contact a few of the good companies like Martin @ pendles or Gareth at GHE tuning and ask questions, they would be more than willing to help T: Also if your engine is in tip top shape regardless of mileage then you have nothing to worry about if it's economy you want.
