“ Very good communication with the customer. All inquiries will be answered quickly with a solution. That's service! ”
“ Good support for self-installation, system functions, better performance with low fuel consumption. ”
“ I was at the company and the installation was without problems. A test drive then showed the subjective performance boost. After a year with the box my fuel consumption has not increased (fuelbook logging). So all is well! ”
“ Product is top! It delivers what it promises! ”
“ Was very satisfied with the fast delivery, and I also was very well advised by a technician over the phone and could therefore install my components without problems in my vehicle. ”
“ My car is now great. I'm very satisfied with the tuning. The installation was easy. The delivery was the next day with me. I had a technical issue that could be resolved over the phone. I'm very satisfied with the product and the support ”
“ I now know my car barely. I never thought that it works so well. Will naturally recommend it. ”
“ I use DTE Systems products already over 7 years. Always have always received exhaustive information, regardless of which contact I have chosen, phone or mail. The products PedalBox and Chiptuning in my opinion are the best you can get on the market, the products have never let me down and do what they promise. ”
“ Expert advice, fast shipping and the quality of products (chip and pedalbox) I can judge well as a former car mechanic. I use both and the difference in acceleration dynamics and performance improvement is tremendous. The chiptuning and the pedal box harmonize together perfectly. I'll also need 1 - 1,5l less diesel. My vehicle has almost a motorsport feeling and I can not imagine driving without them. Great company! ”
“ I deliberately chose a tuning box of DTE Systems, because the increase in performance remains in a realistic magnitude and a certificate of conformity was included. The installation was relatively easy. Just as the acceptance by the TÜV. Was actually quite happy with my performance. However I lacked in some situations more pressure out from below. After installation of the box, the torque increase already in the lower speed range is appreciable. The fuel savings are in my case about 0.5l per 100km. The default setting of the box has not been altered by me. After 2000 km so far there were no problems. The shipment of DTE Systems is very fast. The service is very good, although I hardly had to use it. ”
All Features and Information
DTE have developed a multi-map tuning technology which can optimise up to five different channels, all in real time. Whether it be common rail pressure, boost pressure, turbo pressure, intake manifold pressure or air mass volume, DTE’s PowerControl is able to control them all. Even the latest generation and most technically demanding engines are effortlessly controlled, all within a multi-dimensional multi-map environment. The driver is able to select from 3 different programs: Sport, Dynamic and Efficiency.
The Adaptive Sensor System scrutinizes all the relevant engine data and after detecting its respective load state, will provide more power when necessary. Should the driver demand more power, for example, when overtaking, the system will automatically switch on. If the additional power is not used, the system will gradually reduce the power, all power changes are seamless and dynamic.
Not only are the best performance yields based on engine load state but also on road speeds, that’s what DTE’s adaptive tuning technology offers, more power with less fuel usage.
This innovation allows DTE’s tuning products to learn the unique characteristics of your vehicle. During a short ‘learning’ phase, the chips memory function records the engines injection cycle data and optimises the reloaded maps accordingly. Standard vehicle tolerances are taken into account and an optimal tune is achieved – all without any complicated driver input.
A whole new range of new safety standards are introduced with DTE’s new Engine Protect+ feature. This function has the important task of continually monitoring the ECU’s signals to the engine and safeguarding them against any overloads. The protective functions of the ECU as well as air fuel ratios remain intact and within specification, ensuring complete peace of mind.
The installation of an additional control unit represents a structural change that can result in the loss of warranty and/or loss of insurance cover without registering a parts approval certificate in the vehicle documents. The represented product has not yet been certified with a part approval. Warranty claims against the seller and any warranty claims against the manufacturer may be omitted through an increase in performance via chiptuning or an additional control unit. Before usage outside Germany please inform yourself about applicable national road traffic laws which might restrict the usage to private roads, race tracks or offroad. We will be glad to provide you with detailed information.
