I have a 2020 Ninja 650 ABS. I put a K&n air filter, and a two brothers s1r full exhaust system on my bike. I flashed my bike with FTECU (bike side harness) unrestricted file for my Ecu number. Everything was good except it was running a little lean. So I went and had it tuned at a local dyno shop. They did great job tuning it. It feels so much better than stock. Smooth throttle, sounds amazing, rides fantastic nothing wrong with the bike... But the little orange check engine light. The light came on when they were all done tuning the bike. They called ftecu and spoke to them and they have no idea why a 3A code is popping up. My bike is a non-California model. So in other words that's one code that my bike shouldn't be throwing. My bike doesn't have the purge valve on it.

Tried reflashing the bike.
Tried clearing the code with a code reader
Tried clearing the code by just riding it.
Tried leaving the battery unplugged.


I'd like the light off so I know when there is a actual problem.

If anyone has any ideas it would be appreciated.

Hi Daniel, did you manage to get rid of the code? I'm having a similar problem and there's not much out there about this.

Thanks!

Ii wonder if the ECU has just gone kaput and is throwing a false code.

It could be, but I'm not confident about it. My bike also doesn't use a evap system so I believe that's why the code is triggered, since I also bought an ecu that came from a bike that had the evap system installed as per local laws of emissions.

Well then, maybe there's a way to fool it to think it has one. Maybe a vacuum hose needs to be opened or pinched closed???

Hey man.. I'm currently still having this problem(my ECU is not a California model). My bike has been flashed and tuned but it wasn't until days later that the light came on. The shop I had the work done couldn't get the light to turn off. They flashed it back to stock and tried to clear the code but that didn't work either. Feel like the flash and tune scared the ECU. My solution for the past year and a half has been electrical tape and checking the codes before and after I ride. It's kinda become second nature. However if anyone can shoot me a real solution I'm all ears. Bike runs great though. So I'm going to keep riding! 😁
