1.12.4 ECU VGI 8 Cyl. AEB2568D OBD

Multipoint 8-cylinder timed sequential injection control unit with OBDII function

The VGI AEB2568D 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.
