Yamaha fx cruiser svho wont pass 6k rpm


#1

Hi,
So I’ve been having a problem with my 2016 fx cruiser ever since I installed stage 1 for it. I keep getting 5 error codes on my map tuner regarding RPS, the APS and the TPS.

I took it out of the water to do some research and see if I could figure it out. Something I found was the pipe connecting the cooler to the throttle body was off, so I reconnected it and ran it for awhile to see if it would clear the codes. No luck.

Just wondering if anyone has any advice.

Thanks.
