CAN BUS Compatibility

---

The E46/E39/E38 the M54 originally came in communicated with the rest of the vehicle via CAN BUS. VEMS 3.9 supports this CANBUS

16/12/2022 -
• E36/7 - compatible with BMWs of similar vintage
• E46 - compatible with BMWs of similar vintage
• E39 - compatible with BMWs of similar vintage
• E38 - compatible with BMWs of similar vintage
• E85 - compatible with BMWs of similar vintage

Options at ordering

---

Not everyone is going to need or want the same thing with their ECU conversion.

Ignition outputs
• Stock coils - jumpers in the ignition driver set to IGBT
• Smart coils - jumper change in the ignition driver to TTL and customer will install their choice of ignition coils using stock BMW coil wiring


ECU Model
• VEMs 3.9 : 0 Analog inputs are spare, 0 Digital input is spare, 0 Low side outputs are spare, 6 high side outputs are spare, 1 Relay output is spare.

Injectors
This is a selectable option so that the webstore doesn´t incorrectly calculate shipping cost when customer wants bigger injectors
