Tigger73's 125TSI Tiguan Build Thread

[Sharkie]

As Transporter, said at least you will now be happier with your Tig

To be honest, and not slagging other tuners (much anyway), if you see the actual time and effort spent by APR Australia developing and "localising" each piece of software and hardware they sell (and mostly on cars APR actually buys to do this development on) then you would never go anywhere else .....

Nothing gets released until it has been tried and tested locally, no software from overseas loaded straight onto a customer's car without extensive testing.

I've known and used APR for well over 7 years locally in Australia and have never had bad service or a product that did not meet my expectations. Others may have different views, but there are many many non-APR horror stories out there and I have never met another person who have had a legitimate issue with theur APR products.

Hopefully my last post addresses your wrongful intimation about our software development.

Whilst I agree this is not the place for it, unfortunately your post does nothing to make me feel more comfortable. Far from it. In fact if you read it carefully, my post addresses the extensive development APR puts into each and every tune (as a confirmation to tiggy73 that he is on the right path IMO going forward) and not any perceived lack thereof on your part.

Excellent thanks for clearing that up Sharkie. I wouldn't want anyone reading this to think what I thought your post meant. And Tiggy73 and I too think this is the best path for him on his particular car. I'm the first to tell people if we have the best tune for a given vehicle. I am too the first to tell people if we don't. Simple fact is, as it stands, I suspect we are not putting out as much power as APR on the 125tsi variant - and Tiggy73 was after that from his car.
It's not an issue - any tuner would be an idiot to think they have the most power out of every single model they cover (and also have in mind some tuners do not develop tunes to give the best outright power). Some people of course don't want the dyno day champ - there are many other reasons why people chose different tuners.
I'm happy with the new ranges of tunes on the Tiguans - especially the 147 and 155, but if the 125tsi is not putting out more performance then clearly our 125tsi can have more work done. I have data from competitor tunes on my dyno back to back and know the higher output variants are competitive. I haven't back to backed a 125tsi though so I'm waiting on Tiggy73 to let us know. It will take us time to develop the 125tsi further here if that's the case - and -if- APR can already do it on this variant, Tiggy73 will be happy with his new tune and that's great - whatever the outcome.

Cheers

I'm still not totally discounting a hardware issue with my car - possible rear section of exhaust causing problems???

However putting on an APR tune file which has fairly well documented performance will tell me whether my slower 0-100 and suspected reduced power/torque outputs are tune or hardware related.

The difficult thing that I have had to work with is the lack of any benchmarks with the Viezu tune as the current files are pretty new and not many Tiguans (other than a couple of 147's) are running these. Other than the recent dyno day in Adelaide and posted/claimed 0-100 times from people running various tunes, I haven't had much else to benchmark my car against to know if I'm getting the expected performance/output.

I suspect my car is missing 15-20kwaw and this is what I'm chasing.

The thing I haven't done and probably in hindsight should/could have is put the car down the 1/4 mile. But then again this won't tell me whether I have a tune/hardware issue or if that's all I'm going to get from the stage 2 file/hardware.

Hi Tigger, what is your 0 100 value from APR and Vezu, I am sure if you did not launch the car it will not be very good value. Also I heard even though people say 125 , 147, 155 all same engines I heard there are considerable differences in performance when under tune to get same power levels.

non-launch 0-100 times have been relatively consistent - around 7.1-7.2sec. I ran a 7.2sec with APR file today on a 30degC day.

I have done a couple of launches with my "old" Viezu file and got 6.2sec which is quite a way from the mid 5's most people with APR tunes are achieving.

125TSI should be tuneable to the same point as 147/155TSI as hardware is identical. However it will depend if the tuners have done the work to develop the 125TSI files to the same point.

Would be interested to hear times from 125/132TSI with APR (both stage 1 and stage 2). Obviously there's also going to be some variation in terms of timing equipment etc that people use also. I've done mine using my autopolar FIS+.

Hardware is always a difficult thing to go through - however insofar as the exhaust is concerned - the DP is a slightly tweaked Golf R DP from VARdesign which has great results, and the catback is very close in design terms of the first generation VARdesign catback for the GTi 6 Golfs - which were putting out some savage power in testing, and coupled to the new vTracks are just ridiculously fast - so your exhaust should be doing what it should be doing. What we could do with is some other Tiguans down there - I'm happy to fly down and make it worth their while with pricing just to make it happen. Could do it at a dyno day and live tune it with Technical online or something.

If it turns out to be nothing - normal - We're looking to drop a GTX onto a Tig up here as part of development - maybe you should just jump in feet first and do it I'll come down again for you and tune it and install some other development goodness whilst I'm at it

I'm almost certain it's not the exhaust as I was getting similar 0-100 times before the catback exhaust went on. I'm just going back to what has changed on the car.

But then again it could be that performance I'm getting is "standard" for a stage 2 tuned 125TSI.

Still looking for some comparison data as to what I should expect.

We'll probably organise another dyno day early next year. I'll let you know when it's on if you want to come down - interstate visitors are always welcome to our monthly events.

Hmmm tempting... but I need to get to the bottom of current tune file/performance/possible hardware issues first before looking at doing anything else.

[tigger73]

Now I know car tuning is a touchy subject with people aligning themselves with various brands. However I'll say this upfront that this is not intended to start a tuner war. If you want one of these just start by posting something a little controversial in the tuner thread and wait until someone bites. What I'm looking to do here is document my experience over the last 18 months with getting hardware/software to tune my 125 TSI Tiguan.

I have gone down a path with Simon/Viezu Australia who was looking to develop hardware/tunes for the Tiguan (as well as a host of other vehicles). The reason I went with Viezu was because they offer great value for money and were the only tuner prepared to invest in developing stage 2 Tiguan hardware (exhaust systems in particular). This has actually encouraged tuners like APR to develop solutions for stage 2 Tiguans which has only benefited the end users/consumers. Without this competition, people would be left with the only option - to go and get a custom exhaust made.
