Your opinions on this? Am planning on purchasin it this week. Talked to their tech support about it,name will ask world Motorsports about it when I go in tomorrow for my Rado FMIC.


The VR Tuned team is proud to introduce you its brand new kind of add-on box for the Mercedes-Benz C 250 CGI W204 . With a brand new outlook, a durable and absolutely waterproof shell, this new product will please you. This add-on box will be delivered already set according to your vehicle details so that you will get the announced power. By external adjustments, it is also possible to choose different modes depending on your desires. This provides a unique feeling for all kinds of driving.
The Evolution Programmable ECU VR Tuned is provided with AMP plugs (high quality plugs used by the automobile manufacturers). To improve our add-on boxes reaction time, these Evolution boxes use the last generation ultra fast microcontrollers. Those microcontrollers transfer immediately the data to the ECU.

Within a deceptively simple unit, both in terms of look and connection, the Programmable ECU VR Tuned encloses state of the art technology and materials especially formulated for the constraints of automobile use. A thorough approach for maximum efficiency all VR Tuned units are equipped with connectors that are OEM compliant. If the connectors are not available direct from the manufacturer, they will be made in compliance with specifications that are every bit as stringent as the constructor's.

Unlike some other competing products, computer connectors are never used, as these are not suitable for the demands of the automobile sector. The VR Tuned connectors are secured, i.e. you cannot possibly connect them the wrong way round.

This VR Tuned connects between the original engine control unit (ECU) and your car's injection system. The VR Tuned intercepts data from the ECU, optimizes it and then sends the newly modified parameters to the pump. Only the amount and the duration of the injections are modified, and NEVER the injection or turbo pressure, which remains set at the standards laid down by the constructor. Of course, connection is carried out using OEM compliant connectors, and does not require any adjustment or soldering. If the VR Tuned electronics detect the least operating problem, the system will immediately return to the original configuration. So rest assured, your engine never runs the risk of stalling.

In addition to give you added driving pleasure and flexibility, the add-on unit, in the same driving conditions, reduces your vehicle's fuel consumption. Due to the increased torque, to reach the same speed you don't need to press so hard on the accelerator, so your consumption naturally decreases.

It goes without saying that with VR Tuned, all of the other functions of the control setup (ABS, ESP, onboard computer, etc.) remain active.

Turbo protection along with all other original safety systems remains operational. If the Programmable ECU VR Tuned electronics detect the least operating problem, the system will automatically return to the original configuration. The injection pressure continues to be regulated by the original computer, in compliance with the engine speed, and therefore the accelerator pedal. The turbo pressure continues to be regulated by the original computer. The turbo is therefore never subjected to mechanical stresses any greater than those of origin. To ensure discretion, once you remove the unit, no trace of it will be found in the motor or the original computer memory. The VR Tuned only connects with original connectors designed for the automobile market, and never using computer connectors. Correct contact and sealing are therefore guaranteed.

Can this tuner detect different ethanol levels? Such as the difference between 91 or 100 octane? Do you know if E85 would be an option?

Are there any tuners that also increase boost even by a little?
