Idling is unstable

MOTOIKE · October 2021

When I flashed the ECU [2CR-8591A-60] of 2016YZF-R1M, idling became unstable.

It feels like a few cylinders aren't igniting, and the engine stops a few seconds after starting.

The images used are the following downloaded.

- 2016 R1 - 2CR-8591A-60 (US) StockECU.ftm

- 2016 R1 - 2CR-8591A-60 (US) Unrestricted.ftm

What kind of problem can you think of?

Hi,

That ECU you have is from a US bike or a JP bike?

Thanks,

Jason A.
