    2012 camaro tries to die on coast

    2012 ss
    maggie making 10.6 psi (3.2 upper 10%od lower)
    kooks 1 7/8
    catted x
    built bottom end
    stock throttle body
    cam 566/576 222/234 113lsa
    ID850
    twin 405LPH (Return style) 60PSI static fuel pressure

    when coming to a stop this car always wants to die and barley catches itself. you can see after WOT the fluctuation (note this is on on the Dyno with the load on 12%)

    here we go. i have also read something about scaling a tune with ID850's. Why is this needed and if i need to do so how do i go about do it? i half to do it to a lot of the Fords i tune due to them seing over 200% load.

    No scaling required on the fifth gen Camaro PCMs for ID850s.



    Definitely needs more idle air.

    idle airflow needs to be adjusted, and also the PE throttle Pedal in lower rpms has around 35%tps

    maybe there is a conflict, between your enabling PE 90kpa and throttle table.

    i got the stalling to go away, now the idle afr is going everywhere. at start up it goes rich then leans out to 15.6ish then after the pull it goes to 14.4 then starts going lean.

    also on a side note is it normal on the 5th gens after a flash to take for ever to come up to 1.00 commanded EQ. it always start at .88 then after about a Minuit if finally hits 1.00
