What is an ECM on a motorcycle?
An engine control unit (ECU), also commonly called an engine control module (ECM) is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance. The fuel injection system has the major role of controlling the engine’s fuel supply.
How to find the ECM code for a module?
A: The ESN must match the ECM calibration code family/type. For example, if the ESN is for an ISX CM871 but the ECM Code requested is for an ISB CM2150, this message would appear. Please verify the ESN and ECM Code. Note: Enter the ECM calibration code without the ECM Code Revision. Q: My module is ROM booted, how can I find the ECM Code?
Do you know the ECM code for cm2150?
A: The ESN must match the ECM calibration code family/type. For example, if the ESN is for an ISX CM871 but the ECM Code requested is for an ISB CM2150, this message would appear. Please verify the ESN and ECM Code.

When to install a new ignition or ECM on a Harley Davidson?

When do you change the password on the ECM?
The TSM/TSSM and ECM have “learned” passwords that synchronize the control module with several other components. Once you remove a component from this chain the module shuts down and won’t start. This is reported to only occur with EFI models but the new 2004 carbureted models demonstrate the same shut-down when changing the ignition module.
