The RICA i-Power unit connects between the original engine control unit (ECU) and your car’s injection system. The RICA i-Power unit intercepts data from the ECU, optimizes it and then sends the newly modified parameters to the injectorsystem. In some cases the manufacture can see that the car have been tuned ( even if the car is programmed back to stock with the original software ) With the use of the RICA i-Power unit, this is not the case since the original software is remain unchanged. The RICA i-Power unit will also not be effected in anyway by software updates performed by the dealer. Of course, connection is carried out using OEM compliant connectors, and does not require any adjustment or soldering.
