Mk7 GTD ECU Remap from Carbon Chiptuning! Case Study with Dyno Dynamics plot :-)

[Carbon-Chiptuning]

After extensive development and testing, Carbon Chiptuning are now proud to present to the public our highly developed performance upgrade for the VW Golf Mk7 GTD.



This is a very eagerly awaited upgrade as the latest version of EDC17 ECU used in the Mk7 Golf is installed from the factory with a very high level of security by means of Checksum/RSA protection of the software within.

This means that up until very recently it was impossible to change even 1 bit of data in any of the files inside the ECU without causing major trouble, the only option for tuning these engines was by means of a “Tuning box” or ”Tuning module” which just isn't what we are about.

As most of you probably know we ran a Mk6 GTD ourselves that was used for development and testing and allowed us to offer a very polished product to many MK6 GTD owners over the past few years.

We have now been running a Mk7 GTD since last year and have been waiting in the wind for the Checksum/RSA protection to be worked around so development could begin...........









On 20/06/2014 we were able to successfully read and write the software to our GTD and on 20/06/2014 development began 

It has been a very intensive development cycle with many many man hours spent making adjustments and data logging to get everything just as we wanted it.

As with all of our developments the majority of the work was completed 'on the road' with final adjustments made on the Dyno.

This ethos ensures that what we offer is very 'driver focussed' as the majority of our adjustments are made based on the way the car drives and the data logging we complete in the real world!

We have found our approach gives us the absolute best in terms of drivability and power delivery.





Our own car has delivered a whopping 220Hp and 370Ft/lb (Dyno Dynamics) on completely factory standard hardware. Power delivery is very predictable and well mannered like all of our upgrades.... OEM+

We are delighted with the results on the dyno as well as on the road. The car makes and holds within a couple of % of peak power all the way from 3700rpm upto 4300rpm! And generates over 300Ft/lb all the way up to 3850rpm!

This upgrade is available for both Manual and DSG cars.





Step by step guide to the process:

Firslty, we very carefuly remove the Shear head security bolts that hold the protective cage around the ECU. This allows us to extract the ECU itself.





We take great pride in the physical side of our work as well as the software side of things and as such we make it extremely difficult to tell the car has been worked on by a third party. Please see a close-up picture of the metal cage and lack of any markings where the shear head bolts have been removed. These bolts are replaced with genuine VW items once the work has been completed.





Next we very carefully open the ECU casing giving us access to the circuit board inside.



We then attach our specialist programming equipment to various points on the circuit board. This allows us firstly to bypass the checksum/RSA protection, then make a backup copy of the entire ECU software (all memory areas)

Once we have a full backup we can proceed to analyse the software and make a modified file for your car.

YOUR modified file is then written back into your ECU.

Everything is then re-assembled, including fitting genuine VW shear head security bolts so externally the car is identical to the way we found it.

Now the fun bit – The test drive 

The Price for this service is £475.00 all inclusive

We can perform this upgrade as a discrete mobile service (non-liveried vans)

We allow a 3 hour slot to complete the work

Well this is popular

Shame really as if you were to experience their work then no one would be interested in a tuning box 

A remap will always give a nicer drive over a tuning box 

[Mohsin]

Exactly - this is the sort of thing I would rather have. Something specific and unique to MY ECU..

Like I said on the Mk7 main board, great company and certainly know their stuff  but I think the fact the maps are more detectable now due to the TD1 flags, more people will be turning to the tuning boxes.

[monkeyhanger]

The box does have the advantage of convenience - easy to remove for visits to the VW garage, easy to sell on if you switch from diesel to petrol on your next car, cheaper than a remap. The boxes out there are enabling far bigger power increases too.

For all those reasons I suspect most will go the way of the box.

Just look at the meticulous work that the tuning company had to go to just to apply the map - that map can't be undone without expertise or more labour charges should the car need returning to VW for warranty work or servicing. Commendable work but entirely inconvenient.

I was speaking to Nick at Carbon about that yesterday, and he confirmed as I thought.. once the initial work has been done the car can be flashed as normal through the OBD port.

That's a lot easier than my first impression, so you could have your original map flashed back and VW would be none the wiser about the work that had taken place? Then flash back after you've been to VW?

That would depend on if it can bypass the flash counter

Equally, given how the ECU works, it will be interesting to see the power outputs of a car fitted with a tuning box after 12 months

our Skoda is now 10 months old and is still producing similar figures on the same dyno even with double the ambient air temperature, so I'm not sure why you think customers should be worried after using a box for 12 months..
