Title: remapping a mk5 golf gti
Post by: natalietaylor91334 on December 09, 2014, 10:37:05 am
I am considering having my golf gti remapped for some extra bhp. it has currently got a miltek cat back fitted. I have been quoted £150 to get it done but I have been told to be careful when getting remapping done pretty cheap. He claims he gets his maps of a franchise called uk chiptuning/regaltuning. Is it likely to get any problems with the ECU after its been done?

Has anyone had their GTI remapped?

I wouldn't personally get a plug and play map (especially that cheap) if there is any weakness in your engine you won't know until it breaks. If you got for a live map they will do a health check and test run to make sure your car is in tip top condition.

Only when the car is good will they proceed to give you the extra power so you can drive away confident that you can floor it without fear of problems.

I know of someone who had a cheap map and ended up buying a new ECU  :sick:.

Hi Natalie,

We get this question coming up now & again and the advice we always give is to go to a reputable tuner which is recomended by the forum. That way you will be getting a product which has been tried & tested many times, which will give the optimum output for your car.

There are plenty of places that offer £150 remaps which are generic files with a few parameters changed to give a bit more performance. I've lost count of how many guys have come back onto the forum saying "i've had my GTI mapped by xxxx tuner and now its going into limp mode" or something similar. The outcome is they then have to spend another £300- £600 getting a proper remap by a reputable tuner.

Have a look in the Performance Modifications section of the forum for feedback on different remaps  :happy2:

As above, get a proper tuning company to write a custom engine map, or at least install and configure a Revo "off-the-shelf" map. As with most things, buy cheap, buy twice. :happy2:

Oh, and once you do a remap, you'll find something else will need replacing, something could do with being swapped... It's a dangerous, slippery slope to poverty and it's start with "just a remap"...

Leave it well alone
200bhp is more than enough in a fwd car especially in these cold damp conditions!
If anythibg buy a limited slip diff atleast that way you stand a chance of putting the power down  :happy2:

What a silly comment. Who on earth buys a Limited Slip Diff for an almost standard car at 200hp when you are nowhere near the limit of grip/traction.  :laugh:

Back to the OP - Stay clear of cheap remaps from franchises that get their maps from 'file suppliers'. Most are shockingly bad. Revo, GIAC, APR all do very good software for the TFSI.

Disagree but there you go!
A diff before more power is the point i was getting at mate although still say over 200bhp is waste of time/money in fwd car
Been there and done it with a 320bhp mk1 focus Rs and ruined the car im affraid

I can't belive the mk5 doesn't have a LSD !!! i swear the mk4 gti did ! (sorry to get off topic)

Does it just snatch the front brake of the spinning wheels or something ?

No Golfs have ever come with a limited slip diff from the factory apart from the Mk7 which has a quasi electro-mechanical LSD.
On the Mk6 you could specify an electronic diff called XDS this is also something you can enable with VCDS. I've been playing around with it lately with good results.

That's because it was a Ford focus. :signLOL: :signLOL: :signLOL:
The focus RS mk1 diff was terrible to live with, well known. Great car but as a daily driver on cambered roads, it's a pain!!
Diff's have moved on.

Mk5 platform can handle the power very well and you don't really need a diff unless you are going above Stage 2 levels of power. Arguably with an Edition 30 then at a Stage 1 you would see some benefit if you drive the car very hard but on the road for normal use it's not that imporant. Throttles are modular after all ;)

Im still driving mine with 530hp on trackday tyres in these conditions fine allthough its not a daily i dont think i would have any issues if it was just to potter about in.

How are people having issues stock :s

A stock mk1 is probaly worse then a 360hp gti

I can't believe mk5 Gti doesn't have a lsd either, ive just sold a 1986 escort Rs turbo that had lsd fitted for god sake  :grin:

A stock mk1 is possibly one of the best fwd hatches of all time mate, as said earlier a ruined mine by mapping it etc but even with 317 bhp and 360ftlb torque it still put the power down better than a stock gti in all conditions

As said in another recent thread im either selling my Gti and going all out mk7R or sensible option could be fitting a lsd to mk5
Title: Re: remapping a mk5 golf gti
Post by: Pikey Motorsports on December 09, 2014, 02:10:02 pm
I drove one years ago briefly so couldnt really comment but arent they not known for huge torque steer and poor traction? my mk2 rs running 450hp was probaly worse then my big turbo gti now

Get a 7r if you feel its to much hp, a lsd wont make no difference on the road really

A ford focus it may be but still worth twice a mk5 Gti for a minty one  :grin:
The diff in the mk1 was epic if let at standard power, just takes bit getting used to and need taking by the scruff and actually being driven properly  :driver:

Couldn't disagree more about the mk5 golf platform handling the power at stock levels never mind stage 1 or 2  :rolleye:
Sold my mk1 focus Rs and went for the mk5 Gti as wanted a more usable everyday car that i could enjoy especially with our 1st daughter on the way when i sold it in Jan this year etc
Mk5 is great in lots of areas to live with but when it comes to even a mildly spirited drive in even mildly damp or cold conditions i absolutely hate the thing lately

All of above posts are only my 2 pence worth and no offence intended!
Think maybe im just done with fwd cars and need some 4wd action  :congrats:

Got the wifes mk5 Gt tdi 140 for the sensible booring drives

Sorry if you've already said @Matthewsimone (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=10426) what tyres are you running?
Title: Re: remapping a mk5 golf gti

Michelin ps3 mate  :happy2:

Post by: dansmith180 on December 09, 2014, 02:42:36 pm
Oh... Strange you're having such problems, I'm running 260bhp and 1st and 2nd gear are a bit pants in this weather but that's to be expected however 3rd and above are fine, maybe a bit of spin or torque steer occasionally but its not a problem for me.

As you said though each to their own and that's just your experience.

As I've said in numerous threads, linear throttle mapping and linear delivery (with decent tyres) makes 300+bhp totally usable.

Linear throttle lets you drive on the limit of traction with ease, stock throttle mapping makes it tough to modulate power and stop he fronts from spinning up  :driver:

@RedRobin (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=13) has "only" ~260bhp, yet with an LSD and decent handling mods he had lots of traction and a great all round package -despite having a K03 turbo which IMHO is much more difficult to get traction with than a K04  :happy2:

If you haven't got LSD money (like most) then Anti lift kit and superpro engine mount with a quality linear map should give you plenty of grip at a fraction of the price.

If you do get it mapped GO TO Rtech in Hinckley the best around, I got on a stage 1 255bhp with 310 nm of torque (approx figures).

....Yes and no.

Anti-lift kit and engine mounts (all three! as the rear mount is the most important for traction) will certainly help traction but a LSD goes a big step further when putting down power in the corners. It's in the corners where an LSD delivers its advantages.

The type of remap will help but really the bottom line is how you use your right foot when you are talking about traction. Remaps are simply how the power is offered to you - The bottom line is how you as an individual driver use it.

Although I am very happy with my Revo Stage 2 by JKM, I would recommend R-Tech too.

All in my opinion.

4wd for the win  :laugh:
Yes you lose power through transmission blah blah blah but the simple answer to that is just run monstrous power and easily transfer it to the road  :driver:

At the end of the day, people's driving style and personal preferences always differ, so while one person likes a 500bhp+ FWD car, another won't. Personally, I'm happy keeping my GTI down at about 260bhp, more than enough for daily duties and driving around London.

I do think there's a strong association with power levels and type of roads around where a person lives. Since moving to London, I've stopped wanting big power in favour of a comfy interior and better ride.

So getting back to the original question, a decent re-map from a respectable tuner is the best advice if you want one, but perhaps consider spending the few hundred quid on other things you may enjoy as well (lowering springs, better stereo ect.). Have a look through the Mods section (link along the top red bar) and see what takes your fancy.

@RedRobin (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=13) definitely wasn't implying that they'd be as good as an LSD but for about 15% of the price they'd make a good difference, didn't know about the rear mount though, you might have just cost me money  :laugh:
