The kit is based on the original VW engine management system which has been heavily re-engineered making installation into earlier vehicles as easy as possible while retaining the all its advanced features.

Custom ECU software for the original VW ECU has been developed in house to allow the engine to run correctly without the need to have all the other vehicle systems such as the dash, immobiliser and ABS in place while retaining all the required sensors and safety systems and increasing power output from 200bhp to 255bhp.
