1.12.3 ECU VGI 4 Cyl. AEB MP 48 OBD
Multipoint 4-cylinder timed sequential injection control unit with OBDII function
The VGI AEB MP 48 OBD control unit with LPG sequential injection and OBDII integration are one step ahead of
the current control units installed on modern vehicles with indirect sequential injection.
These evolved control units allow information to be received from the original petrol control unit via the OBDII
diagnostics outlet, pursuant to the protocols of standards ISO9141 and ISO15765. Thanks to this connection, when
running on gas, the AEB control unit is able to monitor vehicle carburetion parameters constantly (thanks to the
petrol control unit correctors), thus keeping the parameters at optimum values.
This integration means:
•
better engine performance;
•
guaranteed top performance even when the mechanical components of the gas fuel system age;
•
automatic adaptation to the different gas qualities available on the market;
•
more information available to the installer regarding vehicle function which makes tuning the system easier.
