When I worked at an authorized Honda dealer in 2018 I did see our techs use the proprietary Honda diagnostic computer the dealership owned to reflash 2018 DCT Goldwings that exhibited stalling. The software in the diagnostic tool is continually updated by American Honda and authorized for use by dealers.All this "reflashing ECU " by your dealer ... I don't believe it.
For enthusiasts, this is intended to improve the vehicle's performance. From what I know, it is quite an expensive operation with PGM-FI parameter adjustment, often with a complete replacement of the factory ECU software, thorough testing and the addition of additional engine control and regulation devices.
I do not think an authorized Honda dealer and technicians would get Honda's blessing for such modifications, especially during the factory warranty period.
I just bought a new 2021 NC750X DCT. I have over 400 miles on it and the bike has stalled on me 5 times now. Today after riding 50 miles on the freeway, then riding in stop and go traffic, taking off from the light the bike will either hesitate, or stall. The more miles I put on the bike the more it happens. It has stalled 5 times now. I took it to the shop, the mechanic said it is all computerized, there is no adjustments. WTH... Does anyone have this problem?
The dealer scan tool in motorcycle or cars does not have the capability to check or debug software.. The question is, can modern Honda diagnostic tools diagnose defective ECM/PCM software?
It was a rhetorical question taken out of context here, which is:...The dealer scan tool in motorcycle or cars does not have the capability to check or debug software...
Hi there Ron!Unfortunately I don't know what type of reflashing they did on mine. But Tom the Service Manager at Honda Metuchen NJ would know for sure.
I will call him on Tuesday to let him know bike is running well now .No new stalling issues after 230 miles today .
Hope this helps.
And to think I had people on here just a couple of weeks ago telling me this stalling problem wasn't happening to enough people to be deemed a significant issue........Just to update this thread, Honda has announced a full safety recall on 2021 NC750xd (dct) models worldwide to address this issue. The fix is mainly a newer ECU program (via flash update) that several owners seem to have already received. Honda will contact affected USA owners after the first of the year via letter.
Mea culpa. To my credit I did say if it is deemed a problem like the 2018 Goldwing was it will be addressed with a simple software update.And to think I had people on here just a couple of weeks ago telling me this stalling problem wasn't happening to enough people to be deemed a significant issue........
Not sure if this was directed at my response which I closed with:And to think I had people on here just a couple of weeks ago telling me this stalling problem wasn't happening to enough people to be deemed a significant issue........
I worked in Warranty for many big brands including Mercedes Benz and Honda and I have never heard of a dealer charging for warranty work, especially as he was unsuccessful in solving your issue. As I am sure you know Honda now accept there is an issue and a recall. Contact Honda about a refund for those charges.They should not be charging you anything if the bike is still in warranty.......shady dealership....
Absolutely true, but it is just a commonly used anachronistic word like “dialing” a phone. However we all know what is the intent.I worked as Aftersales Technical Trainng and all manufacturers have updated software for a long time . It is a long time since they flashed ECU’s. The last time I did flash one was in 1984. At that time you took the eprom out of the ECU and fired a flash gun at it to clear the memory and then reprogram . Now you update software the same as your computer.
