Hi all. Im sure this has probably been covered before so apologies if im covering old ground. Also before I start I am aware that a bonafide remap and DSG remap would be outrightly the best option but I'd want to keep the warranty intact and a tuning box is the safest bet.

Basically has anyone on here put a decent tuning box (something like a DTUK) on their DSG equipped CR 170 and if so what improvements did it bring? Anyone rolling roaded one to see the max power and torque outputs?

Concious that the DSG is soft limited to 258lb/ft so I assume that thebmax torque output wouldnt change, just power output and points at which max power and torque are developed.

Id consider a tuning box at some point if the general consensus is that they are worthwhile even on a DSG equipped car with the soft torque limitation.

Be interested to hear from anyone with such experience.

I would avoid the box at all costs to be honest, I have used one on other cars and they are rubbish when compared to a proper map.

You are better of going with either the bluefin or waiting for the new Shark device. these devices allow you to remove it from the car when you like.

Yes it's more expensive but in the long run it will be much better for your engine.

depends where you get the map done, the dsg can be mapped too to up the limit, hold gears longer etc, Shark performance do DSG maps aswell as a normal map may be worth contacting them

Why not get a handheld unit with a specific map for your car on it? I got one from chippeduk for myBMW. There is also bluefin. Probably other do it aswell. All the benefits of a cutom map with the ability of removing the map come service time.

Why would you want to remove the map come service time??, the dealers will know its been mapped not matter if its a tuning box or a self tuning unit.

How will they?The one i had wiped the ecu so it didnt show that the map had been re-written?

Thanks for your responses guys but by and large youre all missing the point. Reason I want to avoid a "proper" remap is that it will by its very nature invalidate the cars warranty. Firstly the ECU has to be opened up to get around the encryption, so immediately cover for the ECU (probably the 2nd most expensive under bonnet component after the engine itself) has gone. Also any tech worth their salt would pick up on it being remapped and a dealer would sensibly argue any related warranty claim. Also a dealer is likely to overwrite a remap at some point which means revisiting the tuner, opening the ECU again and remapping, admittedly they probably wouldnt charge for that but its an inconvenience having to take the car back.

With a box, its removable, yes if a tech went to the trouble of data logging the car they might notice increased historic boost and fueling pressures but they wouldnt look for those sorts of things and it would be v difficult for them to prove as there would be no physical evidence of it being on the car.

If my car was older (its only two months old) my view would differ but as it stands i dont want my ECU physically removed and opened up and I dont want different software on the car right now.

If there are no positive views of any tuning boxes on a CR 170 DSG ill likely just leave it standard.

Dont think you read my post. The remap i had was a handheld unit plugged into the OBD port. I had this done on my last car which was a 58 plate BMW. It was a specific map for my engine that the tuner emailed to me and i uploaded onto the hand held device then transferred to my car via the OBD port.

The only reason this wouldnt work on your car would be if this method wasnt possible for some reason but i couldnt comment on that but im sure others will know if there any reasons i.e encrytpion etc.

Granted it would still invalidate your warranty but my point was the dealer would never know so whats the problem?

My car is a 2013 model with a tricore encrypted ECU; as far as I am aware it is not possible to ODB map one of these. In any case such a map is 100 percent traceable and not what I would want right now.

Fair do's. How are they traceable out of interest? Must be something that newer ecu's are capable of that the ecu in my beemer couldnt do.

I run a TMC box on my 1.8TSi DSG (7 speed). Admittedly not the same beast in either way but I can vouch for the effectiveness and reliability of their products

There is a counter that gets incremented each and every time the ecu is written to; some tuners say they can reset this but im not sure in reality that its possible. Basically if youve written to your ECU it will be quite obvious to a Skoda tech if they had reason to look at it.

How will they?The one i had wiped the ecu so it didnt show that the map had been re-written?

Jeez!! your living up the last part of your name fella!!

They will see how many times the ECU has been accessed and written to, they will see the car or more the engine going outside its normal parameters set by the manufacturer.

THEY WILL KNOW!!

Now the next thing is finding a reputable remapper that can map the car so it doesn't go way way over those paramaters and personally i feel Shark do that well, Despite Ben's cheery tone!

It was this counter that got reset each time i changed my map so that it always looked like the ecu was untouched. This was a specific feature of my map and one of the reasons i chose it.

Im wondering if a plug in box leaves a tell tale trace on the ecu then? i.e does it show up as a fault or something.

Jeez!! your living up the last part of your name fella!! Ask a simple question and get a bell end response.

THEY WILL KNOW!! Very informative.

I suspect that if the engine is running beyond the original parameters, error codes will be recorded (nothing showing by vcds on mine). With a plug in box the signals between the ECU and sensors are tweaked without altering the map/ECU in any way so the BHP/lbft gains are not huge, presumably because of this, to ensure the engine cannot run outside the limits set on the original map. With a remap, these limits can be adjusted so a better, more effective, map can be generated but equally this could enable the inexperienced mapper to run the car beyond safe limits.

If you had a 58 plate BMW, it would expect that it would have been EDC17. Once EDC17 has been modified it can be traced even if the map is put back to standard with a handheld unit. The only way to erase this is to open the ECU and reprogram the original entire backup file (not just the original map).

SEE......shark_90 never misses a good remap posting.....

I have the same car mate and I researched this the same as you. You do indeed need to physically break into the ECU in order to reprogram it.

Most mappers will tell you they have done loads of em and never had an issue with warranty however I for one ain't risking it till warranty has expired.

Christ one guy on here has had his warranty voided cos his engine was playing up he booked it in but left a photographers card in his car for a race day and his car was on their website lol. I'm jussayin I don't think its worth it till no warranty on car.

My 2 cents.

thats my main worry about a remap on my Octy. I remapped my Fabia using one of Shark's STS units (which was awesome by the way) but my car was way out of the warranty at the time so i didn't worry about it.

Cheers for that TheWood1978 would not consider a remap until it was well out of warranty...at which point i suspect id have panicked about it going wrong and had replaced it anyway.

Im still not sold on the tuning boxes but a good one sounds a pretty good bet, plug in and get a stronger power and more even torque curve without physically (other than the wiring of course) changing any of the OEM hardware or software. I dont really think the car needs more than 258lb/ft of torque but it would benefit from more power and a flatter power and torque curve; i do wonder whether the attempts to increase the torque output would upset the gearbox and throw it into limp home or bring up a gearbox error? Also 500 quid is alot of money to spend on something that could do more harm than good i guess.

Part of me does still wish i'd said balls to it and bought a TSi but i know id not be happy with the higher running costs or much poorer MPG if I had.

Its not just never misses a good post he gives the right answer and no wool is pulled over our eyes.

I like a straight honest business.

"i do wonder whether the attempts to increase the torque output would upset the gearbox and throw it into limp home or bring up a gearbox error?"

The 1.8 TSi puts out 250nm as standard, as does the Twincharge 1.4 on the Fabia. The 7 speed DSG is used only in applications up to 250nm but mine is putting 300nm through it and some of the mapped fabias, much more, without problems. I'm sure there must be others with the 6 speed DSG that have mapped/ tuning boxed their cars well beyond original spec without issues or I'm sure it would have been posted to death on here.
