Not sure, TDI tuning boxes are a brand so could be any engine. On a personal level, I want to squeeze more from mine, but really don't at the same time haha

 

A car ceases to be a car when the engine blows.

 

Saw a really nice looking 2009 Octy estate recently adorning some poor sods driveway with an unfixable 2.0 TSI lump that had liquidised its innards, he wanted a grand for it, which is a lot for a front garden ornament!

Just a little update for you all. TDi tuning are a brand. Not just for diesels. 

I fitted my box on Friday, immediate difference. Especially low down. It plugs into the supercharger map sensor, and the manifold map sensor. Boost gauge has been monitered on every one of the 7 settings and the most it sees is just under 2.6bar (absolute) so just under 1.6bar boost. So hasn't pushed it too far, performance feels good and nice and linear. On the dyno tonight after work to test all 7 settings for figures, not that I care about numbers, but will be a nice reference. The box claims 221bhp as their figure, we shall see. 

221BHP ........

 

How much was this box ???

They're 300 something for the box and fit yourself. The figure I saw was smaller than that though.

 

Would be interesting to see how its split over the 7 settings.

Well, figures aren't brilliant.... But the AFR was good throughout. It still made decent power don't get me wrong, but not what was stated. 

It made 202 bhp and 295Nm on settings 1,2,3 then 4 made 206 297. 

5,6and 7 all made 209 and 299.

With the box unplugged it made 174 and 237 so a little bit down on stock but a gauge to work from. 

Thanks for the update, look forward to hearing what its like to drive, if you can feel any difference between the settings under normal part throttle operation, also if it does not throw up fault codes.

There's no fault codes, but it's very well maintained anyway. Power is nice and smooth, no flat spots, seems good. Really noticeable in the low down and mid range. See what time brings. 

So do they offer a partial refund if it does not do whats stated ?

 

It's almost like false advertising.

Crazy talk, dyno figures aren't accurate anyway, a twenty percent increase for £300 is entirely reasonable.

To be fair its much closer to the claimed figure than I would have expected than anything be it box or remap from any company, they all exaggerate and if you dont join in then you wont get the sales.

 

A rolling road will never be accurate enough to give accurate readings, an engine dyno would be needed, as the baseline figures were less than the manufacturers ones (& they cheat as well!) then I would say the power gain is what was advertised.

Might be crazy, I never claimed a figure and failed to produce it, they did.

Real question: is it worth what you paid for it?

Is this a joke ? 2.6 bar ??? I have a 300+ bhp vrs that runs 2-2.05 bar maximum and that’s on water meth

Yep, absolute pressure. Read the post mate, 1.6 bar of boost. 1 bar of atmospheric, 2.6bar absolute pressure

1.6 bar of boost is a lot on a standard turbo for such a little gain  , baring in mind mine is running 1.7 bar and maxing out the standard injectors

Not necessarily. The amount of air a turbo will push is a function of the turbo size as well as the boost pressure. A big turbo at low boost can push as much air as a small turbo at high boost. That said, 2.6 is pretty high for any turbo to run; it would be interesting to see where that sits in the turbo's compressor map.

1.6bar of boost..... The other bar is atmosphere, I must of written it wrong clearly, 1.6bar of boost..... Equating to 2.6 absolute.

So?! It's happy enough. 

You wrote it absolutely correctly, you could not have been more clear.

 

Some people see what they want to see.

I'm well aware of the difference between absolute and gauge pressure thanks!

Are we pretending that the standard engine doesn't run on high boost anyway for a 1.4? Lol

Any update on this? Not melted your engine yet?

There is some real guff in this thread about using a tuning box on a 1.4 TSI / 1.4 TFSI 132-135kW Twincharger.

Loads of information on what not to have or do from those that never had one or did anything with them.

 

Plenty members used the 3 wire TMC box or the BlueSpark box on CAVE & CTHE's before remaps were available and totally issue free. (The South American TMC was a problem.)

A Stage 1 remap might have been preferable but many never went that way and then the REVO stage 1 map was crap.

Telling it like it is as always.

I have used tuning boxes in the past.  In my experience, they can throw up fuel rail pressure errors when cranked up to the max, not consistent errors, but more inopportune random ones which require turning the ignition off and back on again to clear.

 

ive had an 2014 A6 tdi which never threw an error.  I’ve had a 2016 Discovery Sport that never gave any errors, only to have the box reset for a 2018 3.0discovery that randomly gives fuel rail errors.  The 2014 fabia 1.6cr also gave fuel rail errors.

 

the boxes were from a long standing diesel tuning box specialist that has featured in many magazine reviews.
