Ecm = ecu ?
Are "ECM" and "ECU" different terms for the same part ?
I have a 2009 Fit with ECM code 83-1 and also P0303 Cyl 3 misfire.
I just replace the ignition coils & plugs.

Those are interchangeable. ECM is Electronic Control Module and ECU is Electronic Control Unit. However, with most newer vehicles including the Honda fit...you have a PCM. Powertrain Control Module. Difference is it also controls the transmission.
