The board design is very modest and seems to prioritize light weight and simplicity over robustness.
: Take as much care as possible when troubleshooting in and around this module.
: A professional-grade application of dielectric grease around the connectors seems advisable.
:* '''NOTE:''' Ensure that the entire connector and pins are clean and dry before applying.
; Performance and Lockup
: The board communicates with the bike's other systems via [[Wikipedia:CAN Bus|CAN Bus]], which is a 2-wire [[Wikipedia:Multi-master bus|Multi-master bus]].
:* This means that multiple nodes on the bus must initiate a transfer.
: The board also has limited memory, I/O dispatching, and computational performance.
:* So, it can get clogged with requests for data outside its designed parameters.
:* So, running any telemetry while in drive mode through the OBD-II serial console or using the Bluetooth transmitter will meaningfully increase the load on the board.
:*: In some cases prevent it from acting on rider inputs, including safety interlocks like the cutout switch or kickstand interlocks.
: Reportedly, 2017 and newer models have increased performance and doubled memory capacity.
:* This enables an onboard upgrade with an atomic swap of versions by holding new and old firmware versions simultaneously.
:* There's no known means of using these in older models.
; Electrical Vulnerability
: The circuits connected to the pins seem to lack significant protection against shorting faults, which could be a source of breakages while dealing with connected systems.
; OBD-II Serial Output
: The use of the non-standard OBD-II port most easily draws power from a very limited internal circuit.
: The OBD-II port as a result is typically not usable over a long cable without an external power supply and good quality connections.
