Troubleshooting Fuel Mapping Issues on a Yamaha Waverunner with Link ECU

[catherine]

Hello,

I am facing some gchallenges fine-tuning the fuel map on my Yamaha Waverunner after installing a Link ECU. The engine runs well at mid-range RPMs; but it stutters at high RPMs and runs rich at idle. I have adjusted the injector scaling & tried refining the AFR targets, but the issue persists.🙃

Has anyone else faced similar challenges on a PWC application with Link ECU? I have checked https://forums.linkecu.com/topic/14142-mixture-map-and-closed-loop-aws developerlambda/ for reference but still need advice . 

 

Any tips / base maps you'd recommend to start with?

 

 

Thanks in advance!🙂

Can you attach the map and a log.
