2019 Norton Commando 961 won't start

Just a wanted to give you a quick update on my none starting bike. After much help from this forum I eventually had to send my bike to the expert that is Stu Bodycote at Motorvated. As always he gave me a great service with the bike and declared that the ECU is faulty. He has kindly lent me an ECU why he endevours to get mine repaired which is, as always, a first class service. I want to thank all of you for your help and support with the problem.

You are welcome Sir .
 
Yeah unfortunately it's an ecu fault...looking like being a processor concern.
I spoke to GEMS & also Omex, the two companies behind the development and manufacture of the Donington euro 4 ecu...but unfortunately Norton won't let them deal with me. So, whilst we work on repairing the ecu, I've loaned Tony a 2022 brummie-Norton 961 re-release ecu, to get him back on the road. Once we've sorted the original ecu, and played swapsies, we'll start work again on cracking the firmware/gin file of the Brummie ecu.

Stu, very nice of you. Is it running any differently with the loaner ECU? Start-up cold and hot, idle, fuelling at below 3000 rpm, full power curve behaviour?

To be honest, cold start and cold running seemed very much improved when compared to another ecu on the same bike running a like for like spec calibration file. Idle speed was very steady, albeit a little low at 1,000rpm hot...but keep in mind I was unable to set the tps, due to a mismatched gin file. For me it felt a little flat at the top end by comparison though.

Thank you! Do you have an explanation for why it felt weaker at the top?
 
My 2015 Sport did the same thing. Junked the original starter for an afternarket Sportster starter and never looked back.
 
It's a processing fault within the euro 4 ecu....and repairing it is proving hard work.
