    Misfires when cold only?

    Hello every one,
    I have some issues and I'm at a dead end. I installed aftermarket cams and have been chasing misfires since, they only seem to occur during first "cold" start up the car seems to run fine after and off idle it seems normal.I have included a recent auto scan and some pictures of blocks 208, and 209.

    Code:
    Chassis Type: 1K (1K0)
    Scan: 01 02 03 08 09 0F 15 16 17 19 22 25 42 44 46 47 52 55 56 65

    cold values read: block 208 Engine speed 760/phase position 121/intake cam offset -3.0KW /Adaptation 00100001
    block 209 Engine speed 760/phase position 73/Exhaust cam offset -1.0kw/Adaptation 00100001

    normal operating temp while driving/ coasting all the same except the exhaust cam offset is at 0.0 kw and both adaptations have changed to 00100101

    Im kind of new to all of this so bear with me please

    Thanks in advance Chris

    Thank you for posting a full Auto-Scan.

    How do the spark plugs look? Are they the correct plugs for this engine?

    With the engine at idle, what are your readings in Measuring Block 032?

    Block 032 are as follows
    Idle adaptation bank 1 sensor 1 -0.2% Adaptation Partial bank 1 sensor 1 6.3%, adaptation bank 2 sensor 1 -0.9% Adaptation partial bank 2 sensor 1 3.9%

    The 2 dtc"s for Catalyst system below threshold is due to the Cats not being present this is not a new change

    Do you have the ability to flash to stock or second controller which is stock to verify the cams are timed correctly?

    Many times I have seen people install cams incorrectly......
    The tuners are in addition sometimes at fault........ due to have deleted the cam correlation DTCs or changed the threshold negating the report of a problem.

    Many request this being to lazy to take the engine apart.

    Jack,
    No I do not have a stock ECU. My tune is from United Motorsports and it is an Adaptive ECU tune and from what I understand it "accepts" changes. If the cams were installed incorrect wouldn't I get poor drivability through the rev range? hiccups? why do the misfires go away or seem to be ok once I drive it for a while. I found a DIY for Vr6 timing on the web and it mentioned TDC on the countershaft sprocket also which I did not do nor did the bentley manual say so.I will ask UM if they change these perimeters any other thoughts ??

    This photo includes goofy looking multiplicative fuel trim that Chris sent to Support via email so I figured I'd post it.

    I have contacted the tuner ( UM) and they said the cam correlation and DTC's for cam errors have been retained and therefore it would show any of those errors. They also said blocks 208,209 looked perfect.

    Indeed Multi.....
    In my experience........... never trust.......verify everything.

    I would be looking real hard at MAF, ECT, IAT and air leaks cold.

    It is possible they are sealing as heat of expansion is observed, specifically at intake to head or injectors..... and don't forget booster signal, verifying diaphragm.

    All,
    Just a quick question if it was MAF,ECT,IAT< etc why would only 1 cylinder misfire and it also run poorly off idle??
