    Default LMM-3200rpm fueling discussion

    Many are aware of the 3200 rpm fueling anomoly that occurs. Nick posted a curve in another thread that shows it. HERE The lambda table does not extend above 3200 as he also pointed out. Perhaps this discussion could serve to discuss ways that have been succesfully used to tame this. Since shifting occurs at this rpm under hard throttle conditions, the transmission needs the relief IMO. The mics open.

    Never seen this before in my logs. May have to go back and look. What happens when shift timing is changed to say 3400rpm?

    I'm not sure if you meant this to be the problem but remember on all tables the end axis value doesn't mean the table doesn't work beyond that (or wrap around), it just means it uses the value in the 3200 RPM cells for 3200 RPM and up. So you loose control beyond 3200 but a value still exists.
    I no longer monitor the forum, please either post your question or create a support ticket.

    If I can add to the discussion with logged conclusions, I will. Not clear on what the issue really is.
