rb26 over fueling

Hi My GTR 32 is overfueling. I have Apexi fc management. We checked afm and oxygen censor. stil nothing. stock ecu and still did the same
any idea guys?

coolant temp sensor might be faulty

change that already including afm aswell . Can the exhaust sensor have anything to do with overfueling

Have you checked your fuel pressure?

Are you sure it is over fueling and not perhaps running lean?

yes if your lambda is faulty that will affect fueling

you can turn off the O2 sensor in the PFC

I did turn off the co2 on the pfc. Still the same. So far I replaced water temp sensor afm. Lamda sensor checked all boost pipes. Thought problem was on pfc but changed to stock ecu still the same.

lol hit and miss......maybe its your fpr, vac leak?
