Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 An idiots guide to M3W ECU's

I do not have Protune or the skills to do the tuning myself so I did get help from a local custom motorcycle workshop.

If I understand this correctly they read in a M3W map in the new unlocked ECU and then did the tuning of fuel/airmix that was not working before. With Protune you can live-tune so you get the response directly in the engine while testing. Interestingly they did the tuning driving on real roads as the could not get the M3W on their rolling road.

I bought the ECU from the motorcycle shop but here is a link to a US company selling the ECU: https://vtwin.parts/supplier/ss-cyc...cycle-ss-cycle-ss-vfi-module-kit-55-5090
