Afternoon Ladies and Gents, new to the forum and mk7.5 gti performance ownership. had the car 6 months now and looking to have a revo stage 1 map flashed in on my first service (next friday with 7k miles on the clock) decided to do the first service early as will be keeping this one for the next 6-7 years all being well.
I have never had a car mapped before and do 15-17k miles per annum, just wondered if anyone has any long term reviews of having this done with REVO just as reassurance if you like it wont compromise the reliability. I understand ill loose the manufacturer warranty when I get it done so just wanted to make sure its not going to cause any issues further down the line. Any advise or experience would be gratefully appriciated.
Thanks

No reason to expect a Stage 1 tune to cause much drama.
Of course if it does, its on you to sort out.
You'll probably find the biggest problem is that you've got a lot of traction issues and could have clutch ones at some point.
-
Would you say i would have clutch issues even if the car is DSG? (apologies if this is a stupid question)
-
You shouldnt have any issues with DSG, manual choccy clutch is a different story!
-
Thanks good to know! and finally do you go APR or REVO? APR offer DSG tune aswell as engine tune where as REVO just offer the engine tune. cost is about the same just dont know which one is best as it seems not many 7.5 GPF owners have done this yet. again any advise or experience appriciated
-
I cant comment on which one is better for 7.5's with the GPF fitted, but both companies are reputable with lots of testing done on the car prior to release of the tunes.I would personally go APR with the DSG tune. Im sure others on here have views about which is better, you can also use the search function.
-
Have a APR stage 1 on mine with a R600 induction in my 7.5gti pp dsg. No issue with gear box. Car drives superb tbh. I did wonder if I needed the dsg map too but not necessary unless going stage 2 etc. As for traction, as expected, you're spinning in 1 and 2 depending on weather conditions but top of 2 into 3 :cool :grin:
-
I thought the Dsg map has nothing to do with increasing the power capability but was about changing the shift points and in particular trying to fix the thing where it holds the red line for too long in sport mode.

Yes this is correct as far as I know too. All about the points of gear change etc.

Tvs is supposed to be the best for dsg.

I was looking at them, they do a 'driveability' tune for the DSG, supposed to sort a lot of the common problems.

I'm thinking about it too 👍

It is tempting other than causing warranty issues. Seen a few reviews and people do seem pleased with the results.

You shouldnt have any issues with DSG, manual choccy clutch is a different story!
Out of interest, what's so dodgy about doing it on a manual clutch?
I couldn't imagine having more power, my wheels spin too easily :grin: (but could be to do with my sh!tty tyres). On the other hand the GTi has such a linear acceleration combined with a quiet engine so I can easily see why people would want a remap

From what I have read the manual clutch can't handle it, DSG has two clutches to share the burden lol.
I was and am looking to Celtic Tuning. I did buy an Emotion box to plug in and do myself so I could re-flash after service etc but the ECU on my car is a bit newer and would need a tech to do rather than DIY. Once done though they can programme the Emotion box for me. Service this week so I'll look at it in next few weeks.
The CT map S1 for my car takes it to about 365bhp

Doing 15-17k a year should be a big decision maker in the route you go.
I do 12-15k a year and investigated all the options last year. My conclusions was that whilst the REVO SP3 would be easiest due to plug &plug, it would still be better to a get a custom map that was specific for my car due to the stresses and types of journey I do.
I looked at REVO map installer/tuners, but all the numbers and suggestions were pretty similar and none seemed bothered about milage only 'max power'. DMS however were different and was my final decision, so if I still have the car when it falls out of warranty next year i'll be taking it there. They said they could do 320hp and 480nm, but they suggested 300hp and 450nm with a progressive (less 'spike', in my layman's terms) power banding for the remap so I would see good benefits but also remain in decent tolerances for my milage/use. They will also modify the DSG shift speed, paddle reaction speed, line pressure (clamp). They also map target RPM on downshifts for rev-matching etc
HTH :)
-
REVO would supply a lower boost map if you asked them directly. Their standard maps tend to be a bit boosty in my experience. My old Polo GTI 1.8t could spin up through the first three gears before moving more than a few yards in the soaking wet with minimal provocation :grin:
Smoother less ‘spikey’ maps are definitely better for a daily driver. Big torque spikes are fun for weekend boy racer cars but aren’t good for turbo or clutch health.
Clutch pack clamping is a big benefit to handling the extra torque a remap puts through the gearbox so it’s a major reason people go for a DSG map aside from the more user friendly shift points and quicker responses.

Revo have DSG software... https://www.onlyrevo.com/product-details/software/volkswagen/golf-vii/182/dsg-software-stage-1
-
Most tuners have dsg tunes but I think if it was me id be going with what's regarded as the best and that's TVS.
-
I've been running REVO stage 1 since about 2 weeks old and currently over 4 years old and 25k miles with no issues on a manual. I do have the manual map with slightly lower torque though at 450NM and 370BHP. All good here... :wink:

I've had the DMS engine and DSG maps for a while now, and they're perfect IMO. Progressive is the right word; it feels stock, it's linear in the power delivery and finds a really nice mix between instant shove, and almost diesel-like in-gear flexibility thanks to the torque.
The biggest difference I've noticed with the DSG map is the clamping force, with much less slipping than the stock map. The stock DSG map would ride the clutch at times and you could feel it doing it; the DMS DSG map doesn't, and combined with the torque of the engine map makes it really flexible and easy to live with.
And yet at the same time, it doesn't have move when you poke it!

Really, really want to get this done, but I'm on finance (PCP). I'm 90% sure I'll be keeping the car at the end of the term, but I'm just not 100%, and that's what concerns me. If I were to get it done, and then traded the car in (at VW, which even if I do change the car is unlikely) what is the process for hand back? Would something like this show up?
-
Unlikely they'd spot it on hand back.
If you actually hand it back to VWFS it goes straight to auction after a visual inspection.
I'd really suggest never handing a PCP car back if you can help it though, there is almost always some equity.
More likely though on PCP you are still in warranty, in which case it *could* be picked up on a warranty claim and then VWFS will also get shirty with you.
-
Sorry, when I say hand back, I mean trade in (part ex, whatever)
I didn't get the car brand new - it's now 3 years old and I have a year left - no more warranty to worry about, unless I'm very much mistaken.
Car was registered October 2017, I got it in June 2018. Warranty therefore finished in October 2020 as I understand, and my deal ends June 2022
These cars _do_ have a 3 year warranty, right?
-
I've part-exchanged remapped cars in the past and I've been honest about it, and never has the dealer complained.
But if you get the remap done by a reputable company, most of them will offer a service to revert back to stock if you need. It will still be detectable technically, but only with very close technical examination of the ECU software which is highly unlikely. More realistically is a test drive as part of the trade highlights the car feels very different, which prompts quesitons if you don't disclose it.
-
That's kind of what I expected, I thought you'd switch back to stock and they wouldn't dig deep enough to find it.
And the warranty? Mine is already up, right? 3 years from registration?
-
It is technically possible for them to discover either ECU reflashes back to stock OR the use of plug in tuning boxes.
Whether they do depends on who is looking and they won't look unless you are claiming for something relevant and expensive...
Yes, 3 year VW warranty from day 1.
-
Ok, my warranty is up then. I thought so.
I already have a JB4 on my car, as it seems up in the air as to whether they can detect tuning boxes or not (I gather it's more from looking at engine logs, rather than a straight up yes or no flag), so I've already taken that part of the risk! Took it off when it went for a service and they never mentioned anything
-
I'm never quite sure what a proper map gives you over the box? Something I presume but what is it?
-
More power, but more importantly I think it gives you more low down. You have to really push on to the top of the rev range to get the most out of the box, I think. The map changes way more parameters
-
Boxes tend to trick or fool the sensors into thinking something is happening where a proper map has actually adjusted engine parameters. I'm sure someone more technical will come along with a full explanation. JB4 is the only box worth having and don't get me started on dtuk rubbish they sell :grin:
-
I know there is a slight difference in the components, but back in 2015 I had the S3 saloon and I had the stage 1 map through Revo which was about 350-370 and I did 20,000 miles of absolutely thrashing the sh!t out of it constantly as I was still a bit irresponsible as I was only 20. I never had any issues with the engine, the only thing that did get too hot sometimes was the Haldex coupling and I would have to turn the car off and on again, otherwise I was driving an S3 with front wheel drive only, which was quite fun actually and surprisingly fast about 4.9 - 5.0 seconds to 60mph with FWD only, obviously it was around 3.9 with the 4WD. Never had any engine issues.
I also had a REVO stage 1 on a fiesta ST and I battered the crap out of that too. I swear by REVO. I'm currently running a £175 map on my GTD and although it is nippy, it is a bit lumpy and a bit inconsistent. It feels like it makes it mind up as to how much power it gives me, sometimes stockish power, then when its in a good mood it feels more like 225-230ish and occasionally has a flat spot in 3rd and then a big surge in 4th. I have learnt my lesson about sh!tty maps and will be visiting Devil developments or Revo when I have a bit of spare cash
-
Oh and the S3 was DSG btw :grin:
-
I think we've learned as much about your driving style as we have about Revo! :grin:
