Tuning for VW 147TSI (2011+ Jetta)

[davodinkum]

oooh yeah, specially in the mid-range.
normal driving there is not much difference. but punch it, and u'll feel the wowness!!

exciting stuff to hear! that's what i'm looking most forward to

Theres a fair jump in power going from stock to stage 1, expecially in torque on the 2.0TSI motor. You will definitely notice the difference.

As a rule of thumb, with a stage 1 tune you will end up with your stock flywheel power at the wheels. That might sound confusing, but i mean that your car has 145-150kw from the factory (at the flywheel), and a stage 1 tune will yield approx that same figure at the wheels. So you will end up with around 180kw or so at the engine.

All the 2.0TSI engines i have seen dyno readouts for are making about 150kw at the wheels with a stage 1 tune.

i'd be happy with that if all goes well with this tune, a down pipe would definitely be on the agenda!

I used to have a Bluefin hand controller and sold it about a year ago to a guy on here with an Octavia vRS and it worked fine on his car. His car was almost brand new at that time so it would have been a similar age to your car.

That was me, and its still working.

mines a 2011 147TSI CCZ motor (yes I know it says TFSI):

^ yep this guy.

hi guys, just an update.

john from DNA just came around with the SRS controller and it looks like my ecu is one of the new ones. He's going to double check with the guys in the uk but its not looking good

might have to consider a bench flash or go with apr

Bugger....although im not surprised. John can do the bench tunes (as he did with my brothers Skoda TDI) so you are lucky you are close by so its not too much of an inconvenience.

does your brother still have warranty? if so, did he have any concerns about voiding the warranty before making the decision? I've still got just under 3 years left. I know about the whole them having to prove a tune was the direct cause of fault if something was to go wrong but it's still always a risk.

Also, with a bench tune, what happens in the event where the manufacturer (in this case vw) do a upgrade of software to the ecu? Does it wipe what's on the or does it restrict them from doing this?

Thought I might ask on here before I chat again with John.

Cheers

Avoid the problem and get serviced outside the dealer network. They can flash over the OBD.

Going with ANY brand of tune is more than likely writing off warranty on most engine and drivetrain components. Although in saying that, he has had his car serviced several times since the tune by the dealer (he does alot of km's, and it had its 45,000km service just a month or so back and its only 10-11 months old) and it has not been mentioned/been a problem.

The car may well have been checked and the dealer has noted it as being tuned, but he has not had any issues with the car so nothing has come of it just yet. Mind you, he was aware of the potential warranty issue prior to tuning.

Same here, i have taken my Golf into VW several times for warranty items and there has been no mention of my tune or aftermarket intakes, dump pipes and other parts. Mind you, my warranty claims have not been mechanical so this is probably the reason why it has not been an issue. My car is most likely flagged as being modified/tuned etc in their system.

And yes, if the dealer does an update of the software on the car it can/will wipe your tune and revert back to the stock tune. This happened to a friend here in Newcastle a few weeks ago and he had to get the tune loaded back on. This is only a quick process and most tune providers will either do it for free or for a small fee (or buy them a 6 pack etc).

This is a decision you have to make if you are thinking of tuning the car. You warranty may be compromised if you have a engine/drivetrain related failure. For me (and many other enthusiasts), this was a risk i was willing to take.

^ thats another option.

[Ideo]

I have 83,000 on my car with an intake and tune. I did get it serviced a few times inside the dealer network with no drama, but now go indie.

My only "warranty" issue was a fix to the creaking door seals, so unrelated to engine.

bluefin came back to me today and said 'it probably wont work' with my car. they're not 100% but i'm not going to take that risk. I'm glad John from DNA is sending me the SRS controller to check my ECU before commiting to buying. He's been fantastic to deal with.

my jetta is a 2011 (MY12) model so fingers crossed all goes well!

Hey mate as I have been MIA from this forum, tried to catch up on most of the posts and came across this thread.

I can confirm BLUEFIN will not work on 147tsi models. Been down that path and had to wait couple of months for a refund. Our MED 17.5.2 ECUs (new gen) seems to not allow 'communication' between the OBD II port and the ecu. Even after attempting the bluefin bench flashing method, that didn't work out too.... I believe this was to do with the bluefin tune 'not spec'ed' for our newer ecus found within the MK6 147tsi Jettas... Spent almost 12 hours trying to crack it with the dealer but to no avail...

It is to my understanding however that if you wanna tune a 147tsi.. The only option is to bench flash them... There are a few options out there today...hope this helps mate?

[Guy_H]

I probably could have saved you and your dealer 12 hours....

You are correct, bench flash only. The ECU part number tells you that so don't waste time trying to do it other methods.

you cant really generalise like that.

I have a 147TSI and my Bluefin worked fine. no bench flash required.

its only that ECU type (and i guess others too) that lacks the capability of a flash via the ODB port

[parso_rex]

There are different ways of communicating with the ECU's even though they may all be MED17's there are now I think 5 (or 7 versions) or encryption that you might have to 'avoid' and then there is the bluefin enable process too. It would certainly be on their list of things to do if hasn't been done already. I know there were a few updates very recently for their stuff and my own - which can certainly do this

I think the time was spent trying to access the processor so they could patch it for use via OBD - I'm too lazy to bother doing this
