ADL3 to ECU wiring (RS232)
The following details the methods for connecting the ADL3 to the various
MoTeC ECUs via RS232. In all cases this is done using the serial data stream
generated by the Telemetry function of each ECU.
In the case of the M800, M880 and M4e the ADL3 may be directly wired to the
ECU because these ECUs use RS232 interface levels. On the M48, M4 (pre
M4e) and the M8, a Computer Interface Module (CIM) or a PCI cable is
required to convert the signals to RS232.
M800 / M880
Note:
• The data to the ADL3 will be interrupted while a PC is connected (DOS
software only)
• The 9 pin connector is not used if using the Windows Calibration software.
• Data may be sent to the ADL3 via the CAN bus as an alternative to the
serial connection.
M4e
Note:
• Older M4 ECUs require a different connection method
• The data to the ADL3 will be interrupted while a PC is connected.
