CR1 chipbox is digital device designed for diesel cars that include a common rail injection system (CR).

CR1 chip should be plugged into cars electrical system what causes the modification of the data exchanged between the computer ECU and each engine component when it comes to:

fuel injection,
fuel amount,
boost pressure,
air temperature,
air density,
engine speed,
throttle position, and other variables.

Chipbox increase power up to 30% - power increase depends on the engine volume and cars power output - it may result in 20 horse power more in a small engine or even 50 in bigger diesel engine.
Chipbox increase of torque from 30 to 50 NM.
Car reaches higher maximum speed, better acceleration, better dynamics and responds better for the gas pedal.
In diesel engines decreases fuel consumption by 0,5 to 1,5 liter per 100 KM.
Eliminates so called "turbo hole" in cars with turbine.
The electronic circuit of the chip is flooded with epoxy resin, waterproof, perfectly protected from moisture, dust, oily coating.
It has a motor protection function (this function prevents overheating of the engine under heavy load - a very dynamic driving).
Digital chip is made from good quality materials, and the wires are placed in the heat-resistant ducts - made in SMD technology.
It doesn't cause excessive fumes emanation.
After removing the chip the car returns to factory settings

Fast and easy installation „PLUG&PLAY” - takes only a few minutes.*

(* there are some cars where the plug is located behind the engine or any other hard reachable places what results in much more effort to perform the assembly. Sometimes there is mechanical help needed because for instance the battery or air filter has to be removed to reach the plug - such models are very rare ones).

You will receive the device ready for installation with detailed instructions!

The device has an additional adjustment in the form of adjusting screw, which helps to conform the device for operating the engine - use it only when necessary. Please contact with us before use additional regulation.
