    Default Decel lean spike/IFR table limit ?

    Played with RTACS a little this weekend. Still get the spike in the VE table on decel that I see when just doing AutoVE. Could this be related to the fact that the Injector Flow Rate table does not extend to this kPa? Don't know what value the PCM is using when you go off the table(more than 80kPa vacuum/less than 25kPa MAP). If it extrapolates with a slope as per a stock 04 tune, then that would explain it. My table is flat due to my modified fuel system(see sig).

    If so, is there any possibilty of extending the table further?

    No it is disabled. Should have mentioned that.
