Got a  DTUK tuning box same as this one

from a friend with a DSG seat cupra, same engine Cuna/cupa 2.0tdi 184 bhp.

So allegedly/apparently the sane engine, and wiring loom is correct for my Octy vrs.

Anyway, tried several programs on this box with mixed results, from it intermitantly bogging down and being flat/ laggy. or other times seeming to make the car feel faster?

But inconsistantly, and more worryingly intermitantly buggering the car up all together.

Has happened several times now, that whilst running different programs on this box, it has then thrown the car into limp mode as described above.

so as of today Ive taken it off and gone back to standard.

 

Just wondering if any other octy or vrs octy drivers have had similar problems?

 

Sounds like the box isn’t programmed to your engine. The Cupra doesn’t come in a diesel for a start, only petrol (I’ve had 3 Mk 3’s, current one is R) so the program for the petrol will be completely different. I run TDI Tuning boxes on both my Cupra R and my Octavia and they are both seamless, giving a noticeable improvement in fuel consumption and power. The DTUK box will need to be reprogrammed to your specific engine - their website gives costs I believe but it will be worth it because it makes a significant difference. 

I cant find my msgs from the facebook seller i bought it off so cant check what he said he had it on, but know it was def a SEAT 2.0 tdi 184hp dsg

so maybe a Leon? he also checked the engine was also a cuna/cupa engine for me.

So I was probably wrong in thinking it was a cupra.

 

I will check, but it came with original box and paperwork, and I thought i saw on the box  "for VW golf mk7, Seat something or other and skoda octavia vrs poss an audi too" but i might be mistaken.

 

Have to say that I am not suggesting re this thread that I think DTUK are to blame or are no good.

But just simply keen to find out how other OCTY VRS owners went on with them?

Im wondering if its worth ordering a new boost sensor as ive heard the mk3 had probs with these.

But preety sure a poor performing or bad boost sensor would not cause a low fuel rail fault code

 

this is an interesting/worrying read

Can't help much but I went for a JF Automotive tune instead of a tuning box in case the system didn't agree with the car for some reason. i.e. they can tweak it to make it bespoke for the car whereas tuning boxes are standard for the engine code.

 

Hope DTUK can help out as I believe they can reflash the box with ease if you send it back to them.

 

You'll enjoy the finished article, makes the car feel a lot more lively and how it should be from factory.

Thanks,

Why not give DTUK a shout, see what they say? From their FAQs page, it seems that their tuning boxes might be more specific than you'd expect.

I wouldnt want to bother the DTUK guys with an enquiry about a 2nd hand box.

I know boxes are car specific as in a box thats been on a bimmer is no good for a Octy.

But im not having it, that a box for a VW group car, with same engine,same gearbox,same ecu and same BHP is going to be different.

donor car was a 2.0tdi 2015 plate DSG @184bhp from a cuna, and recipient is the same.

You only need to look under the bonnet of any skoda,audi,seat etc and you can see same parts Say oil filter under there if the engine is same size / year for example.

I refitted it today for a laugh/experiment, ran like ****e in a few programs/settings.

But seems fairly good/happy on 2.0 or 2 -1

will see how it goes and if it throws up an error /DTC or if coil light appears.

 

P.s.
