    If you have the Ducati ECU vs Bosch ECU, then you'll likely find ongoing ECU problems with the former ECU brand. CFMoto eventually went with Bosch on the later models ~(2015/16), due to the unreliable nature of the Ducati ECUs used through the CFMoto model range. I've replaced my Ducati ECUs on my 650TR (TK) and Jetmax maxi scoot, when both Ducati ECUs died. FYI the Ducati and Bosch ECU aren't interchangeable so the Ducati ECUs will remain an issue, as can be seen on some of the OZ motorcycle forums - guys seeking advice with 650NK or TKs suffering dead ECUs on the older models. I didn't think that the ECU internals would be repairable or know of anyone capable. Didn't give the ECUs a second thought, but now that you've mentioned it, maybe it's worthwhile bringing the ECUs outside of China and taking them to a company like ECUnleashed or similar. Let us know how you get on with this. I'm back in China in Jan '20 so I may very well carry the ECUs out with me to a shop in either SEA or OZ I'll report back on how I get on if I do.
