Running rich... Even when adjusting my regulator "fuel problems"
That's my build with minds listed for reference. So I have taken my ski out the past three weekend. 1st time in Mi ski was running great. 2nd weekend I noticed my Afr were reading 11-11.2. So as I was trying to make my adjustments I found my self two full turns out and still seeing the sane numbers on my Afr gauge. Later that day my Afr gauge read e8 which mean over heated sensor bla bla recommended replace with new one so I did. Now today I got out on the lake and noticed that my afrs were still reading the same. Now when I was in Mi the weather and water temp were colder which would cause the ski to run leaner bringing me to better afrs. So idk how long this might of been an issue. However my main question is what could cause my ski to run rich at wot and not alow my regulator to make clean afrs?

At what rpm your seeng this 11.1 AFR? What injectors and boost?

check your fuel pressure then Try a different set of injectors. Same problem, you'll need to tune the fuel out.

Basically I see low 11s at wide open throttle, however at 7100 Rpms I was able to see 12.0 so some how I am getting richer.
I am am runnning a rude1 (rated same as x charger)with 42s, so I don't think dif size injectors would be the issue I could be wrong tho. Esp since my buddy with an x charger ran fine.

Are you running a stock ECU? With 42s and a rude one you should almost be spot on in the upper end while rich down below. You'll have cylinder wash and 1/2 you oil will be fuel. A ring catches the wall you're effed.

Well take the regulator apart and see if there is any debris or damage to the diaphram or IF the coil could be binding....Also need to check to make sure your gauge isnt messing up..We can hook my LM-2 up to it and see if it reads the same as the gauge...

You running rrfpr or static ( no ref line attached) ? Run static. Set fuel to say 60 and adjust then according Your low 11 wot will creep up to proper level of 11.9. Ish that where you will have to watch afr and add or take a pound
and add a bigger wheel haha
