    Default Real lean at WOT or WB ?

    hi all,

    well i posted last week after noticing that my wb was leaning at WOT at certain points, i though this was a problem with the injetors so they were changed (they were at max duty anyway with my head and cam setup)

    ok so here is the log

    loj_inj_run2.efi

    you'll see at most points when i initially get on it that its is ok sometimes and lean others. Im beginning to think this is NOT real and is something to do with my WB either the cables or the WB itself ? Whats your oppinions ??? Its not at same place and the car obviously runs fine at WOT

    [please excust the rich running, just put injetors in and increased VE to be on safe side to check all was ok]

    just a thought....I've re checked the log myself and where it 'leans out' the NB are still at 900+ mv. These would see a lean if it was real...?

    Most likely... try another LSU4.2 sensor.
