I really don't know too much about remapping apart from adding more speed.
Long term dose it wear the engine more ? Would someone be so kind to post the pluses and the minuses.
Also dose it affect the warranty and is their a remap VW recommend.
Thanks for any info.
There is loads of information about remapping, both pro and con on the internet. Most remappers will have a reasonable amount of information on remapping on their websites too. This will give you an insight into what it involves.
I'll quickly run through some of the major changes on a turbo car: Increased turbo boost, increased fuelling inder load and optimised fuel and ignition timing (well, no ignition timing on a Diesel but more emphasis on the fuelling there).
Does it wear the engine more? Yes, if you drive it hard a lot.
Does it affect the warranty? Naturally; you're putting third party software into your ECU. Is there one VW recommend? No. VW Racing have semi official support with a third party stand alone warranty. In Germany Oettinger used to have a semi-official status, I'm not sure if that still stands and won't be recognised by VW UK anyway. So no. But many dealers won't dig too far unless they think they have reason to.
The most noticeable and most useful benefit of remapping is the increased mid range performance, it really brings the car alive and sharpens up the throttle response. Fifth and Sixth gear acceleration is much improved and you will often find fuel economy slightly improves if you don't drive like you've got a company car BMW all the time (ie. a tw@t)
I've had at least eight or nine remaps on my previous cars and not had any problems so far. Mind you I don't tend to keep my cars that long or drive that hard. It's all about the vastly improved mid range response for me.
