#77724, "just got wideband insatalled...need help tuning"


          

i just got it installed today and for some reason i idle in the 14's at 50psi fuel pressure. i thought i should be rich during idle with the secondary fuel pump, but i cant get it to go rich at all. even through boost it stays around 13-14. after about 5500rpm my boost starts dropping off and it finally starts to come down around 11-12. ive tried adjusting the bleed valve to not bleed of as much but so far it hasnt done anything. any suggestions to get it to run richer. i didnt think it would be a good idea to turn idle fuel pressure up much past 50. i dont have a fp guage to see what im at under boost. thanks. i trie searching and got like 1,000,000,000 results so i thought i would just ask and see what you all think.

your ecu sets the fuel at around 14.7 while driving. WOT you should see between 11-12 AFR. your sensor is right on what it should be.
