    Default P0171 & P0174 SC 2010 Camaro

    E38_0012.efi
    Tune.ctz

    Mods:
    LS9 cam
    2" TSP LT's
    Whipple 2.9L w/ 4" pulley
    3 bar MAP (1bar tune AFAIK)
    JLT CAI (110mm ID at the MAF)
    E85 flex sensor (issue happened before adding the sensor)

    I've reinstalled the supercharger twice in case a ring seal was broken or twisted, and I cannot find a vac leak anywhere!
    No WB yet, my lm-1 seems to have kicked it.

    Thanks

    Does your FPR have a manifold-reference hose... if so remove the hose and check for presence of fuel (i.e. FPR is leaking into reference).

    What is your rail pressure (measured with reference hose temporarily removed)...?

    Are your injectors leaking...?

    Are you injector tables correct for your injectors...?

    For your wideband, you also have to log EXT.AD1/2.

    Your log does not contain HO2S11 and HO2S21... I want to see these.

    looks like 1 bar sd tune based vve, but full time maf for fueling, yikes.

    I think you need to look at doing a 2bar map sd tune by disabling the maf.

    i also hope you didnt pay for that tune.

    Here is a log w/ the added PIDs with the exception of the ad1 which will be a fuel pressure sensor and the wb02 both of which I have not received yet.

    No, its the stock Camaro SS setup w/ a ZL1 pump and should be set @ 58 PSI
    The injectors (Siemens Deka 63lb) and tables are from the tune that come w/ the Whipple kit.

    I have not made any changes since I currently do not have the proper equipment (its in the mail), however the tune was 'made' for this setup and so should have been corrected.

    Measure it (at the rail) anyway.

    Thats the plan, just waiting on the sensor. The Whipple has a port for a sensor but no valve for a quick check
