    550cc injectors and the KRKTE Value...

    I think my KRTKTE value may be wrong for my injectors, causing the lean top end running, (diagnosed as a fuel pump issue)

    mine are set at 0.0597 where as others are all around 0.0725 which allows more fuelling per m/s. can anyone confirm this? aka Bill/tuffty....

    KRKTE on std 370's is around 0.08 odd (would need to look it up...) 550's normally come in at 0.05 odd from memory... my 630's are 0.04 odd...

    Non wideband are tuned differently to wideband cars on WOT... not done a lot with them personally but FKKVS springs to mind which is a correction map... I believe this to be the one that is dialled in to sort fuelling on APY's as the lambda is only used for idle, part throttle and cruise...

    its crazy as to why it did so poorly.
