Attention!

VSI-2.0 DI always installed with MAP sensor/MAP reducer.

Make sure that all wiring connections are connected according the installation manual, with special care for: – VSI–2.0 DI sensor interruptions

– Power supplies

– CAN connections

– Injector interruption

IM location as described in the installation manual because of heat dissipation.

Select correct CAN protocol in case of VAG vehicle.
