The way i see it, is that tuning companies, such as JBS in Chesterfield, have approached specific talented software writers, to produce a unique piece of software that is designed to improve the efficiency of the Vw TSI engine.
The software was fully tried and tested, before it was ever allowed to be used on customers vehicles, and i have not read any negative reports from Up Gti owners who have used JBS services.
Milltek, the respected exhaust manufacturers, thought that the small Up Gti would be an ideal vehicle to experiment on, with the design of a cat back system for the car.
They used JBS, and had nothing but praise for how it transformed the already fun GTI.
Its all up to the owner, to make their own decision, on whether to have their cars engine retuned, for peak efficiency.
If they are ffraid and have never had one of their vehicles remapped before, then at least visit a respected tuning business, and discuss their worries or concerns.
If they still feel uncomfortable about the process, and are afraid about invalidating their warranty, then wait until the car reaches its third birthday.
Its a bit silly preaching to members here, about the dreaded pitfalls of blowing up your engine if you get it mapped, unless you have prior experience of such a calamity.
The Up Gti is my fourth vehicle to be retuned or remapped, and in the future, whatever car i decide to own, i would gladly remap it.
If you have concerns, then simply do not do it, but if your still interested, then at least discuss your concerns with people who do know what their talking about.
All i can say, is that i am more than happy with the JBS results on my car, and can recommend the company to anyone thinking of having their car tuned.
Just to try and help you to understand the basic concept of what remapping actually is, first of all, you’ll need to understand that there isn’t any software writing involved whatsoever. It’s about editing a dataset, with certain key parameters, mainly boost pressure, being determined according to the feedback from various other variables.
With regards to your suggestion that a fellow Up! GTI owner could decide to have their engine “retuned“ for peak efficiency, and with this comment I assume you are also of the misconception that the remap you had carried out has increased engine efficiency, this is also not the case. (Note: volumetric efficiency and engine efficiency are two completely different things.)
The modification you paid to have carried out on your vehicle (despite misunderstanding what you were paying for) has increased boost pressure, and also fuelling commensurate with that increased boost pressure so as to increase the charge volume and hence volumetric efficiency. This despite one of your previous postings in which you informed us that a man employed by or representing your favourite “tuning” company told you that they haven’t increased the boost pressure.
I’ve yet to read any replies preaching to members here of the “pitfalls of blowing up your engine if you get it mapped”, but would be interested to read those if you can point me in the right direction.
Another misconception you seem to have is that the only reason someone would choose not to have their car remapped is through fear ! - Fear of catastrophic engine failure or being faced with a bill they can’t pay.
Everyone has different priorities in life, and although I chose to buy an Up! GTI, I have absolutely no interest in having it remapped and as I have commented before, would not do so even if it was free, and it didn’t invalidate the warranty. It just isn’t something of a priority or that I am desperate for, although I know that may be a little difficult for those who have an insatiable desire for more power to understand. If I wanted a car with more power, I would have bought a car with more power.
With the above being said, I have absolutely nothing against remapping, although I’m well aware that there are many who are excited by the prospect. My comments regarding warranty and insurance implications are simply made with the intention of better informing those who are desperate for whatever additional power increases they can achieve and who may be looking through rose tinted glasses without properly considering all implications. One such implication that has yet to be mentioned with regards to remapping and other modifications is the negative impact on the resale value of the vehicle, which is rather surprising as this seems to be such a hot topic at the moment.
Before the flames start, of course it doesn’t require a great mind to understand why a nearly new car that is void of manufacturers warranty because it was invalidated by the owners obsessive desire to go faster is of significantly lower value than an unmodifed one of identical condition and mileage. However, I would imagine that those who are unscrupulous enough to withhold such information from their insurance company would also omit to declare their remap to a prospective buyer, for reasons they know very well.
