Prins AFC software Licenses

Make sure you have the right software licenses: – Diagnostic VSI-DI – Activate VSI-DI LPG ECU

VSI-2.0 DI software licenses can be installed for existing Prins accounts. Install new licenses, go to: [Info]>>[Licenses]>>[Install new licenses]>>[Check online].

New trouble codes are implemented in the software. – Go to: [Help]>> [Trouble codes], to find the complete list of all

active system trouble codes and possible diagnostic solutions.

New implemented trouble codes


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!

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.
