Hi all,

Been quite some time since I've posted but I was just curious as to what these engines and gearboxes can take stock? Stage 1 map safe? anyone with experience when it comes to mapping this platform?

Just a post for a little bit of advice really, stage 1 is around 370bhp and 383ft-lbs, would the gearbox and engine cope for the miles to come if paired with a TCU tune?

Thanks,

Renox
 
Dsg or manual?
Manual clutch as std don’t last very long!
But can get a low torque map!

Dsg is ok if serviced and can be remapped to match ecu software!

For full stage 1 ECU sw the stock TCU sw will not hold at all...
Maybe a soft stage 1 tune will work but then what's the point of tuning.

Also remember. A proper TCU tune is not raising only clutch pressure and torque limiter.
Also the driving dynamics is change to suit the new power and torque curve...
Go to some known companies like APR and get a complete sw package on the ECU and TCU. This way you will be safe and also most likely happy

Good luck.

Transmission is DSG on mine (DQ250)

I was thinking of going for APR stage 1 HO 98RON ECU paired with the TVS TCU Tune Stage 3 which will be ready for stage 2 if I ever decide to go that far.

Do you personally have any experience with this engine and transmission stage 1?

Cheers

Get the engine and gearbox remapped at the same time, it will mean the tuner can release the full potential of the engine tune.
With the engine you know what to expect. When I had the ECU and TCU remap both done at the same time the DSG tune really impressed me, it made the car much better to drive.

Check out TVS Engineering’s website for the details on the gearbox tune.

Have you tried the APR TCU tune at all?

Hi, I’ve run APR stage 1 HO and stage 2 HO which is about 420+lbs on my mk7R 2014 model paired with TVS tcu tune. Engine, trans and turbo no issues in 80k km and almost 7 years tuned. That’s same engine and dq250 6 speed trans.

I’ve had the usual water pump and haldex failures but nothing to do with tuning. Just known faults in VAG cars.

Just in case you didn’t know APR no longer do stage 2 tunes so if you’re looking at going further than stage 1 you will need to look at others like revo, custom tuners like MRC, unicorn etc

Thanks for this information, really appreciate it, just overthinking about the longevity of the transmission and engine however with what you’re saying that shouldn’t be an issue.

Regarding the TVS TCU map is there anything you’ve set that you don’t like? Also apparently we have to state what rpm you want the transmission to change at (not sure how true this is) if so what did you say?

Cheers

I got my tune 6 years ago. It’s Harding perfomwnce tune which now I believe is rebranded TVS which they have updated on website over time. That’s in Australia. I didn’t pick anything other than back then stage 2 tune which I think is same as what the TVS stage 3 is.

There might be options now about picking more features but for me there is nothing I would change. The gear changes are pretty much spot on in D for both cruising and adjust to moderate throttle and in sports mode revs out hard to red line but happily goes into 3-4-5 gears so you can use it and just have car super lively in the torque power band entire time. It was like giving the car a brain to actually use the right gear to driving circumstances rather than just racing through gears to save fuel or stay in second forever in sports mode.

Thanks for the response, how was the gearbox etc holding up when you went stage 2? I believe there's not much power between the two stages? Is it worth the money to go to stage 2?
 
This is power at wheels last dyno run. My trans is handling it no issues at all.

There isn’t huge difference going stage 2 in top end power. It’s definitely noticeable with increased power and torque across entire rev band and basically removes any turbo lag at all. Whether it’s worth the cost it’s personal, if you love modding car, want extra exhaust note, induction sounds and keeping car long term it’s worth it. If it’s just going off numbers and you’re looking at intake/inlet (recommend on stage 1 anyway for max results) DP, and upgraded IC then it becomes expensive.

If you’re going APR tune they don’t do stage 2 anymore so something to think about. Best value is stage 1 HO with inlet and either modified stock intake with panel filter or if you want induction sounds aftermarket intake.

For most people stage 1 is more than enough anyway. I liked doing the mods in stages anyway. Stage 1, then I take 6 months later. 12 months after that was next was TCU tune, inlet, TMD and boost pipe kit. Then pedal box.

Then DP and stage 2.about 12 months later again. After that bangs and pops tune. Then added res delete to enhance that.

Some handling upgrades- rear arb, later eibach springs. It’s a slippery slope once the mods start. I’ve spread it out throughout 7 years of ownership only finishing late last year when I swapped to open style intake and apr ignition coils.

For me low end torque, sharp throttle response with nice exhaust note and lots of Induction sounds was my goal for car but everyone different.

When you say extra exhaust noise does the APR Stage 1 ECU tune make the pops and bangs louder?
 
APR have a pops and bangs file at stage 2 not stage 1. Where is increases them. It’s not too over the top and only activated in sports mode.

Again it’s not option anymore as stage 2 APR discontinued due to emissions in USA.

If you’re going to stick stage 1 only APR good option but if at all thinking stage 2 then you’ll need to look at other path. Whether Revo, custom tunes etc.
 
The best bang for buck is probably what I've done to mine, that is: intake, uprated intercooler, stage 2 custom tune. Stage 1.5 if you like. Exhaust side is completely stock. This gets you nigh on 400 break and lbs foot. Its not that much more in terms of cost (about an extra 1200 quid) but does give a decent power / torque hike compared with stage 1. More importantly the uprated intercooler means it keeps performing just as well in hot weather or under sustained ragging. I've never noticed any power fade unlike with previous turbo cars
You can get a bit more out of it with a full stage 2 but that gets expensive and I'm not sure its worth the extra. That is: downpipe with sports cat, full exhaust. You are looking at probably 2 grand for that lot fitted, for maybe an extra 25 break? If you care about exhaust noise then yeah maybe go for it, but I didnt and wanted the car to look and sound stock which it almost does. The remap has made the exhaust note sound deeper which is nice.
having a free flowing exhaust side would allow the boost to be pushed up a bit more which is why full stage 2 people are seeing around 420. Although I'm kind of happy with mine running less boost than its capable of, thus not totally ragging the turbo, but still giving very decent figures.

btw - extra pops and bangs with a stock cat will destroy it. so tuners wont do it unless you have something else in there
