TDI-Tuning Instruction Manual

In previous articles we have discussed how easy it is to install a TDI-Tuning Box. In fact, 87% of our customers install the tuning box at home, with the car on the driveway. It really is that simple. But how can it be that simple? We offer over 6000 vehicle variants and we provide detailed and unique instructions for all of them. Installing your tuning box is a simple DIY job that normally takes between 15 and 25 minutes.


How do I install a TDI-Tuning box?

As we offer tuning boxes for so many different makes and models of car, pick-up, boat, and even tractors, we offer a lot of different instructions. As such, every set of instructions is different, this is because the engine layout is different. Below is an example set of instructions, so you can see what you get given when you buy a TDI-Tuning Box.


Every single vehicle install will be different. But you don’t need to worry, as your set of vehicle instructions will be for your exact make and model. The vehicle instructions are sent out with every order, we can also send you a digital version if you would prefer. The vast majority of our installs require you to unclip 2 engine sensors, and connect them to the TDI-Tuning harness. The harness then connects to the tuning box, and you are good to go. The sensors will be in a different place for different engines, that's why we provide installation instructions for every make/model. The installation instructions will clearly annotate exactly where the engine sensor clips are for your vehicle. If you do struggle when installing one of our tuning boxes, you can always give us a message or a call! We don't bite!

Where should I put my TDI-Tuning Box once it’s all connected?

If it's wet, warm, or moving, don't put your TDI-Tuning Box there. No that's not a joke. The tuning box we provide is water resistant, but if it's subjected to large amounts of water, it will stop working and it could damage your vehicle. You should also be careful not to install your tuning box too close to a heat source. It can take the ambient temperature of the engine bay, but it won’t be able to cope with excessive heat. This goes for the vehicle harness too; try and route the harness we provide where other cables are running. This is because, if there are already cables there, it's safe. That brings us to the last tip, if you think anything is protruding on a moving part, such as a fan or a belt. Don't install your harness or tuning box there. Be careful to allow for a little bit of slack for the harness, but ensure it doesn't sag into a cooling fan. It might even be a good idea to run your vehicle with the bonnet up to see what is moving and what isn't. Don't put your hand in there while it's running though! We don't provide strict instructions on where to mount your tuning box. This is because you might want to install it stealthily, or you might want to install it so you can easily access the tuning box. However, you want to install the box, just make sure you don't put the box or harness where it's wet, too warm, or around any moving parts. 


I want more information, is there an instruction manual I can read?

Yes, there is. We provide a detailed instruction manual in a digital format so that you can go through it at your leisure. We would advise all our customers to have a quick flick through before starting an install, as it provides information that will help you along the way. Our instruction manual is made up of questions our previous customers have asked, so there is a very good chance it might hold the answers to any questions you might have.
