Hi all,
I'm new to the forum, own a standard mk5 2007 Golf Gti, am interested in a remap, but a friend says this will decrease the life of the engine, he says that if increased performance/fuel consumption could be easily gained with no negatives, then the manufacturer would roll them out like this from the factory.
What are your thoughts, are there disadvantages to remapping? grateful for any answers

Your friend talks sense.
Think about an f1 car, it will run within 99% of it's limits because each engine is only supposed to do a few thousand miles tops before it craps its pants and gives up.
The gti however is probably built to do 100,000 miles over the course of 8 years (total estimates here). Its not just the bare engine block youre stressing when you map a car, its all the related components. These are engineered within a tolerance level - when you map it, you are getting closer to these tolerance levels.
Having said that, you will *probably* be fine, as you arent exactly gonna be sitting in an f1 car after the remap, and these guys generally know the ins and outs of the car so well that they understand where there is safe room for more oomph.
Just my 2pence.

cheers Maxp,
it's an interesting topic

it is an interesting topic that i thought long and hard about before going down this route. personally i am planning to keep my car for 5 or 10 years so the last thing i want is problems. after reading up a lot about longevity etc i decided i would take the risk and make sure that i dont thrash my car all the time but open it up occasionally. i commute in my car 50 miles a day and normally aim for 30-37 mpg's because im poor! im no expert but i would say if you start to mod your car you need to be prepared to pay the extra insurance and get it serviced regularly. my car came out of the factory at 230ps and i have added atleast a ton on to that but i know that i need to keep my common sense about me all the time. i check my oil every week and warm the car up and cool it down after a blast. at the end of the day you make your choice dependant of a number of factors but the cars come out of the factory ready to be thrashed for 100k and if you map it but look after it it should last much longer. well at least im hoping mine will! :smiley:

As above poor maintenance and cold thrashing is more harmful than any remap.
I tend to find the type of people who are interested in tuning are also interested in looking after their cars so in general an enthusiast driven remapped car will last longer than one owned by someone who doesn't know how to check the oil level.

Seconding this. For example, my last two Ventos. My first was owned by some farmer who didn't really care and it was in poor shape and got poorer quickly. My current Vento was owned by two enthusiasts before me and it is flawless. 16 years old with 90k miles and not a single hiccup.

How do you cool it down?
-
Stay off boost for the last mile of your journey and let the engine idle for a minute or two before switching off.
-
I suspect on the balance of probability it has too. Working the same engine harder will concieviably reduce its lifespan subject to "normal" maintainence etc. However, you could be talking about the difference between an unmodified engine lasting say 250k miles without rebuild with the modified lasting 200k miles say which may be more than the car will ever do.

Whats the verdict then guys?
re-map or not to re-map?
:)

Remap dude!
You know it makes sense! Mota will be just fine if you service it properly, me - Revo n never looked back, car runs perfect and i cane the sh@t out of it - it jus comes back asking for more, but I don't abuse it if you follow me!
cheers

Awesum!
How much would a re-map be on my 56 plate GT TDi then?
-
£250 if i do it.. probably double that if you go with one of the companies that has to pay tons of overheads.

I always thought idle = no movement :. no air to the rad :. water(+engine) temps increasing and possible oil pressure reduction.
Im sure im being a thicko here. :undecided:
The only other thing i can think of is constant low revs, so you are cooling/settling the parts that arent directly in contact with the engine coolant?
-
the engine is bullet proof.. the turbo is not :wink:
-
The GTI is held back on bhp to meet VW corporate mpg allowances.
You are expected to remap it.
Lets VW off the mpg hook, cheaper to tax, faster. You would be daft not to.

What BHP increase do you get? Also better fuel economy?
Also do you just plug in a laptop??
Thanks! :)

On this point i thought it would be worth mentioning that manufacturers are obliged to keep perfermance / emissions within certain constraints for thier production group as a whole i.e taking into account every model they sell, and so may not be able to have the performance quite so high. Also each car is aimed at a different group of the market and so they would have the gti's rolling off the production line out performing the r32's etc.

Obviously more power will stress the engine more, although when done properly it will all be with in the operating safety parameters.
The Vag engines are great and can take the extra power,
You will be looking at about 240 ish with GTI remap and better mpg while cruiseing, i had an extra 80bhp from my mk4 golf 1.8t which i ran for over 50k with only the DV needing replaced (£50).
I wont be getting my Mk5 mapped for another year yet, but when i do i certainly wont have any worries about doing so, an upraded DV is a good idea too though, as well as an intercooler even at stage 1 IMO, revo recommend this also

valid comment here and in agreement :wink:

exactly :afro: and tbh if someone who drives a car doesn't know where the dipstick is or check the oil level and say's i just let the garage do it!! well they deserve to have engine problems :evil:

Remap and don't worry. In 2003 i bought a brand new VW Golf PD130. At 900 miles on the clock i mapped it. When it reached 80k i fitted a hybrid turbo which made the car make 220bhp.. I sold it a 200k. The engine had absolutely no signs of wear at that mileage. I had no failures whatsoever due to the modifying. The only weakness was a slipping clutch which was rectified with a sachs uprated one.
