CB1100 Idle speed instability problem

I'm not sure if any used ECUs listed for sale would even be known as "updated", which is where we could play the guessing game forever.

Potential next steps for me:

1. Find someone with a known good ECU to test with on my bike

Or

2. Bring my CB back to stock, store it in the corner until it's time to say goodbye.



Both the 13 & 14 have been updated to a new part #- which could only mean new software. No way to know what the changes were...but odds are....


I'd say the unless your dealer really knows for sure if there was a specific update to fix the idle issues, it's still 50:50 on it if will work, and for how long. I asked the parts guy who was supposed to be the best one at the dealer, if he knew about any updated part numbers on the ECU for the 2013 and 2014, and had no relevant information. The only thing he confirmed was that the 2013 has its own ECU and other years will not work.

If only the dealer was nice enough to order a brand new ECU specifically for testing... but I guess it doesn't make sense to do it for a some random dude with a 10 year old bike.
