Remapping the mk6 GTI

[Teutonic_Tamer]

I think there's a usable limit to a front wheel drive car, my car's gone off today, REVO are hoping for some decent gains so we'll see what the end of the week brings.

Very true. IMO the MK5 chassis can just about handle it so the MK6 should be more than up to the job of more power through the front.

But the Mk6 GTI IS the Mk5 chassis! 

mk6 chassis has XDS, mk5 chassis does not.

WRONG - the actuall Mk5 & Mk6 chassis are identical.  As are the front and rear subframes, and firewall, and floor pan, and suspension mounts, and suspension geometery.  Yes, the Mk6 can have the XDS, but this is an expensive £700 option, and is ONLY on the suspension.  It has cock-all to do with the 'chassis'!!

XDS isnt worth it, aftermarket suspention mods will do a better job for far less money.

Regardless if thats true or not, thats not the point I was making. The 5 and 6 chassis is not the same.

Sorry, but you have been listening to way too much BS from the VW salesmen - because the chassis ARE identical!

I think your getting mixed up with XDS diff and ACC.

Note the part where it clearly tells you its only added to the new gti. They are clearly talking about the car's chassis and its clearly not the same as the mk5.

Your talking about ACC which is a £700 option, not XDS. It has everything to do with the chassis !

and heres me going away for a week,

my moneys on T_T and rhyso

I'll take you money chuff

affraid TT is wrong on this occasion... XDS is not a optional extra. Its std on the Gti, and probably confusing it slightly with the ACC optional extra. Although I imagine he is correct about the chassis being the same. 

[ub7rm]

The chassis (platform) is exactly the same.  XDS is, I believe, clever trickery with the brakes to emmulate a true mechanical diff.  Its pretty clever and by all accounts pretty effective but as T_T states, cock all to do with the chassis

Oh FFS - READ MY SIG!!!!  I'm an independent technician (and a highly qualified and very highly regarded one too) - and NOT some fcuking marketing consultant paid to dress up a turd.

If you are adamant you think you know better, I suggest you read 'Hilliers Fundamentals of Motor Vehicle Technology' a formal academic textbook approved for all UK colleges and universities, including the UKs leading Automotive Engineering unis.  And - based on what is taken as long-established FACTS, the Golf 6 and Golf 5 CHASSIS are identical.  This is backed up by data from ETKA - Volkswagen Groups official parts catalogue.

Next, for the record, it was NOT me who confused XDS with ACC - read back through the thread, and don't try mis-quoting me!!! 

Onto the nitty-gritty.  Yes, the Golf 6 GTI does have ACC and XDS (optional or standard is a moot point), which were NOT available on the GTI - but both these have absolutely jack schit to do with 'chassis'.  So I'll state again, from my very learned point of view, which is backed up by every athoritative source - the 'chassis' on the Mk5 and Mk6 are IDENTICAL - end of!!!! 

Onto the specifics - ACC is simply an electronic add-on to an otherwise identical Mk5 suspension, with the only real hardware difference being the dampers (aka shock absorbers).  Instead of having just normal suspension oil in them, they have a magnetic-type oil, which basically has iron filings in the oil - these respond to electric currents, which makes the fluid change its viscosity, and therefore its damping rate.  In all other respects, the Mk6 suspension is identical to the Mk5 !!!!

And the XDS - this is NOT, as VWs website claims, a 'differential lock' - but is simply an extention to the software code of the ESP unit.  The actual mechanical differential is just a conventional old skool 'open differential'.  If you actually read page 12 of the printed GTI brochure (which is a legally representational document, unlike completely unregulated websites) - it clearly states that XDS is just an ESP 'tweak'.  It is NOT some fancy real LSD like Audi use in the new B8 S4. 

Get over it, or am I pi$$ing into the wind!

Why do peeps keep on changing their handles?

Although I imagine he is correct about the chassis being the same. 

Weather I got bogged down in what is/was option vs standard is a moot point  - the crucial issue is that neither XDS or ACC are part of the 'chassis'.

Exactly, thanks.  

XDS is, I believe, clever trickery with the brakes to emmulate a true mechanical diff.  Its pretty clever and by all accounts pretty effective but as T_T states, cock all to do with the chassis 

You nailed it.  It just applies the brake to the inside front wheel when turning and accelerating, which is just part of the ESP, in exactly the same as EDL and traction control.  But I don't agree that it is particularly 'clever' - because applying the brakes whilst accelerating is a tad contradictory.  VW would have been far better to bung a true Torsen or Quaife in the front axle - but that costs money - whereas a 50 pence tweak in some software code in the ESP map costs peanuts (probably explains why this is a standard feature, not an option)!
