Hidden menu - CO adjustment - fuel trim

[BurrFabrication]

I just found all of our phazers can adjust the fuel maps for each cylinder. I have been fighting Sluggish response, fouled plugs and fouled o2 sensors.
Mine was +40 on both cylinders. With the rapid bike pullin out huge fuel

What are the boosted phazer guys running for fuel management and what are your CO values for C1 @ C2.

Do the dealers set this up when we buy our machines new, for the intended altitude???

What is your altitude and settings???

Has anyone adjusted their fuel trims?

Yes I believe way back I leaned it out a little.

I'm new to the forum so forgive me if i'm misposting this or something, but how do you go about getting to the hidden menu on the phazer?
do you need some kind of scan tool?

Hello, and welcome to the forum! I think you'll find a lot of great information here. Anyway, I'm sure there is a more direct tutorial on this somewhere, but I can't remember where I've seen it, probably in the Phazer service manual. For now though, hopefully this link to another thread will help a bit. The procedure is down towards the bottom of the page. Good luck!
