Reducer/system pressure adjustment
After mounting a new reducer and during maintenance always adjust the
Idle pressure according target pressure!
– Go to: [Diagnostic]>>[Service]>>[Target pressure setting]
Always adjust pressure with warm engine
Correct pressure adjustment is key for optimal performance!

Installation requirements
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.
