    DOD & Variable Cam, Delete questions

    Customer brought me a 2010 truck
    No start

    it has DOD and variable cam physicaly deleted via enging built.

    5pin connector is loose at the back of the motor
    no variable buisness to plug into at the timing cover

    ?do the conectors need to be plugged in?
    ?do certain DTCs beed to be left on or turned off?

    Cranks but no start
    -has fuel pressure
    -has spark
    -PCM commands PW at cranking
    -PCM works great in another truck
    -good voltage at the coil harness
    -all fuses check good

    2010 4x4 1500 6.2Liter 9.2:1CR large heads and cam Whipple charger

    Note:
    changing cranking AFR has no effect on cranking
    changing the crancing advance makes it almost want to hit

    yes the dod needs to be turned off and codes for the solenoids set to no error report,, otherwise the pcm automatically goes into 4cyl default mode, if it would start it would only run on 4cyl's,, seen this many times

    vvt cam should also be set to none.

    Got that already

    DOD = Disable
    Camshafts = None

    DTCs disabled:
    P0010
    P0011
    P3400-P03457

    cranks no start

    probly need to verify the engine build, crank reluctor and sensor and that the correct 4x cam gear and cover/sensor were used, if you didnt build the engine(who knows what parts are in it)

    I have tried:

    -more fuel & less fuel
    -more cranking advance & less advance
    *adding advance almost made it start

    the plugs were visibly wet so backed off off more than a little

    it is not setting any DTCs

    My gut says it has a cam or crank position sensor issue

    here is a datalog of less fuel

    I'm picking up after another tuner has been inside it already.
    So I changed what bugded me in the tune then went into Diag Mode.

    anyone?

    Digging the sig mods :-)
    BTW
    What does your 2010 A6 make at the wheels?

    yes there could be any number of issues with the build
    from wrong parts to runnout sensor reclutor issues

    the customer is in the know about the motor
    proven local Los Angles builder, I have dynoed the builders motors several times
    I can get all the PNs and info if I press the matter
    Motor is built to non AFM / non DOD / non variable cam.

    the connector for DOD is loose at the back of the motor as it has nothing to plug into

    cant hardly see the Timing over sensor parts

    original 5.3 VVT cover is not on the motor
    a standard LS2 timing cover was used
    with a normal high perofmance timing set

    ? isnt the VVT 5 wire and the LS2 3 wire CPS connector?

    in teh scanner try logging Fuel CUt Type, ETC Source, ETC TqMgt Type, Spark TqMgt Type, Fuel CUt TqMgt Type

    that will give you an indication if anything weird is happening

    What I tryed:
    -Set timing for cranking and idle from -30 to +55
    *would kinda fire and idle for a second at +55 degrees
    -set the fuel from stupid rich to studip lean
    *made no measurable difference
    -pulled the injector fuses and tyied to fire it on started fluid
    *it would not fire on starter fluid
    **duplicated the starter fluid test on near identical whipple truck and it ran good like that.

    Next:
    -find top dead center and make a zero timing mark and hit it with a timing light

    ?if there is fuel cut I would have no commanded PW correct?

    here is it almost starting
    @ 55 degrees timing and low PW
    Put it on jumper cables to my Lt1 caprice that has a high amp alt to ensure good voltage

    how about getting back to basics, did you do a compression test and a leak down test

    I asked
    Shop owner refused to do a leak down
    the motor is zero miles fresh from his proven builder
    maybe he will change his mind as desperation set in

    Just for a sec unplug the maf and try switching on the motor. If it works, its sometimes best to start all over again on a fresh new file.

    Basic test: Does it have spark? Does it have injector pulse?

    Spark = Yes
    *jumped a TR6 Grounded to the head with the strap open to .060+ gap

    Injector Pulse = Yes
    *commanded PW responds to min inj PW or MAF or Cranking VE
    *noid light jives with commanded PW
    *cranked w/ plug out fuel and air mixure ejects on the exhaust storke

    Unplugged the MAF
    in MAF mode PW dropps to commanded min. PW as soon as the motor trys to hit...if it trys to hit
    Swtched to VE and then commanded PW jives with cranking VE

    your MAP sensor is reading boost (125kPa) in the log. Maybe that is a problem? Also, you have a lot of ignition timing, 55 deg is a lot!!

    id check one cylinder for compression. if none, id pull the timing case cover to check timing.
    maybe someone has a stock hpt file???
