Sorry to revive a “Dead Thread” but wanted to share some info. I was doing some research into these tools since I was curious that’s there’s not really an OOB solution for the TR-80 transmission. I was really wanting to hope that these boxes worked as implied.
It appeared that these devices are made by one company and rebadged to the dealer who wants to sell them.
In this case you’ll find that DTUK, JF Automotive, and TMC (all UK companies) sell this device, the unit and “security hologram” look exactly the same with the exception of the logo. And on the three websites you’ll notice that the drop downs for the variants of Audis is pretty similar.
I found it odd no one wanted to share how this device actually worked and how it was undesirable and no one who read back the transmission found any changes.
This led me to believe that all this device does is reset the adaptation, which can be performed though VCDS/OBD11 or even with a manual procedure, and a TCM adaption reset would give you improvements.
I reached out to JF Automotive, who I appreciate for their honesty here, I asked them does this device actually change the shift map, or just perform a reset, they confirmed it was a adaptation reset.
I’m sorry to say you’re paying £300+ for a device that does one thing that could be performed for either free or through a $100 OBD11. While the adverts for this product didn’t necessarily lie in terms of what the product performs, they sure implied it did a lot more.
