    LMM sluggish/smokey once hot at 2000rpm

    All I'm saying is that a new set of any other reputable injectors can buy a lot of crow.

    LMM sluggish/smokey once hot at 2000rpm

    Weird, maybe I'm the only one who has had white smoke from a broken piston, bent rod, or a bad turbo. But in this case he said it clears up, which I would not expect from a whole set of crap injectors, which is why I think more data is needed

    LMM sluggish/smokey once hot at 2000rpm

    I'm not sure there is enough data here to jump on the bad injector train. Nobody asked if the truck is making a big change in fuel quantity when this starts to happen, or pulsewidth, or timing, or what the desired vs actual vane position is doing. These are all relevant variables. A crap turbo...

    P0880/no start after tune upload

    you should probably start by getting a pinout diagram at a minimum and verifying voltage and any shorts on that circuit. Also, I agree that making all these threads stemming from the same work is very confusing.

    HELP No Shift Indicator Line, No Crank No Start

    Sounds like a low voltage issue to me

    DuramaxDiesels.com Forum is up for sale.

    With more investment of time and energy, this forum could become so much more organized and offer information that techs and up-and-coming techs strive for. Heck, I forget about half of what I have learned since I started learning here and it would be incredible to only have to reference 1 or 2...

    Electrical issue

    Could be the BCM. Could also be a bunch of corroded or pinched wires

    Attention LML owners...

    Why would you take away from this thread that the shop who did the headgasket work assembled something improperly?

    LML reduced engine power, bad ecm?

    So you mean that unplugging each one has the same exact effect? Or just unplugging the first one you tried had that effect?

    LML reduced engine power, bad ecm?

    I don't think that's causing the swings in voltage, even if there was a shorted circuit in the sensor. Sounds like a bad ground or a rubbed through harness or something. But certainly won't rule out a bad module yet either.

    Venturi catch can setup

    I haven't looked at the l5p PCV system lately, but lly - lml used the Venturi effect also. The purpose of the diaphragms in the valve covers is to regulate crankcase vapors under high-suction. Meaning that when the turbo is creating enough vacuum in the pcv hose, it pulls the diaphragms shut...

    Learning to read and modify hex and build cax files

    Jesse Bubb offers classes, but they are very expensive for the non-commercial user.

    Finally bought my first turbo............

    My opinion is that unless you still have a good front pipe hangar mounted to the side of the trans, you should run the downpipe flange bolted. I've seen cracked downpipes, broken flange clamps, all many times because of either of these supports being removed. The front pipe hangar is the most...

    LML Need some help

    I have had completely stock trucks with faulty sensors and/or wiring on these circuits cause these issues too. I have also had to argue with the most popular of tuners over this issue because they told their customer that they could not change the tuning to ommit at least 1 of these temp sensors.

    LML Need some help

    Monitor the post-cac temp sensor, fuel rail temp sensor (on the back of the cp4) and iat2 sensor for a cold to warm run cycle and see what happens. If the truck doesn't have all these sensors due to the delete (because the manufacturer mentioned doesn't account for these sensors in their piping...

    LML Need some help

    What is the MAF reading at idle? Also, are ALL your temp sensors and pressure sensors reading correct values under normal operation?

    LML radiator

    Maybe there's a Radiator shop near you that can fix it? There's a great guy near me that brazes,welds, cleans, re-gaskets radiators for a very reasonable price. It's not like they are in every city, but it may be worth a look.

    Neat article, with a glimmer of hope

    I think something like this could easily be publicly funded
