Kit includes parts to add GPS to a MoTeC ECU equipped Mercury watercraft. The RaceGrade OTC-M converts serial data stream from a MoTeC L10 GPS into the M1 CAN Decode format. The serial connection will directly connect to a MoTeC L10 (38,400kbps) GPS device. This serial GPS data is converted onto CAN starting at base message ID 0x680 for decode by an M1 ECU. Additionally, the OTC-M provides the correct 5v power supply for these GPS devices.
