Default P0152 engine code after dyno tune cam pipe install?
I have the PO152 code rich rear cylinder code pop up after about 60 miles of have having a cam, dyno, tune and khrome werks 2 into 2 install. I’ve tried looking what causes up on here and nobody really has an answer. I cleared it and hasn’t came on but what would cause this? Was it the tune, oxygen sensor damaged during install? The bike runs good. What are the odds it doesn’t come back? It was tuned with a power vision. Anybody else get this code before ?

If it's a problem with the tune, it will most likely come back. I would ride it more and if you get a code, take it back to the guy that dynoed it.

Usually a Rear Rich cylinder, Try swapping to a different tune.

I called the dealer and said they’ll look at the file and adjust it. I guess it’s rich down in the lower rpm at some point. Hopefully they can see where it’s rich at. It happened when I was coming to a stop one time and going down a hill the next. It happened twice in 150 miles. It runs perfect other than throwing the code out of nowhere.

It happens sometimes after a dyno tune. Usually it will clear itself after some miles and not come back. I would not worry unless it comes back.

ok thanks I’ve rode it about 140 miles and it came in twice on me. I didn’t know if it would quit after I put quite a few miles on it or not.

I would give it a little more time. If it continues then I would take it back to tuner who did work.
