Regarding this my bike S1 FZ6N
May i know the difference between this two ECU
5vx-8591A-00-00
And
5vx-8591A-20-00
Are this two interchangeable?
Im looking a new ECU for my bike
Ive found a brand new ECU but it has the (20-00)
The S2 FZ6 incorporated the O2 sensor that the S1 did not have. Between that and possible pin configurations, I would say stay with the series made for the bike.
