    LML Callies Durastar Crankshaft Issues??

    There was 90 in first batch of Ultras. So do the math. Still 100k if one bad batch... Sent from my SAMSUNG-SM-G890A using Tapatalk

    Crank / Cam Signal Emulator

    We went over it end to end checking ground resistance, battery banks wiring, ecm grounded, ungrounded, nothing made a difference. Then when we setup the second engine, we lifted the bail connecters up and away from the injectors, and it never cut out once. Neither engine had a factory bail mount...

    Crank / Cam Signal Emulator

    That's what I had in mind. My little $30 Saleae knock off doesn't give ya voltage to duty. But I might grab my buddies SnapOn scope and log both a stock truck and this bench setup to see whats different. I really want to replicate that misfire issue we experienced to rule out any reflector or...

    VGT compounds

    Yeah, we actually learned the 2x T4-61mm Nelsons were TOO DANG BIG for a Duraamx in a sequential configuration. With smaller 80% injectors they would make about 32lbs boost open scroll with lots of smoke and lag below 2500R. We blocked a scroll on each housing, got em up to around 35psi with a...

    Crank / Cam Signal Emulator

    On a side note, I've been unable to replicate the high RPM misfire issue we experienced on the dyno, and attributed to signal interference on the crank / cam lines. I've even wrapped the signal wires around a couple injector magnets, no luck. Haven't hooked the scope up again yet, but guessing...

    Crank / Cam Signal Emulator

    These cleared all the injector codes. However the old Pyramid inverter couldn't handle power demand to fire em. Once I hooked up a battery, they danced around on my desk like jumping beans... Its cool to hear the differences in pattern when pilot shuts off. Think if stick a piece of aluminium...

    LML Callies Durastar Crankshaft Issues??

    Easy enough to check em. As Gabe demonstrated, dial indicator on the damper and a big pry bar on the flywheel gonna tell ya real quick.. My monies on a batch issue, which should narrow it down easy enough. Or it could be a batch of super hard thrust washers flaoting around out there. I also...

    LML Callies Durastar Crankshaft Issues??

    I know it's springtime, but hearing crickets from up in Fostoria is a bit strange.. Kinda expected some sort of statement by now. Maybe they have someone out racking up 10k miles on a truck to verify it... Sent from my SAMSUNG-SM-G890A using Tapatalk

    Twins with Twins, Anyone?

    Anybody have an old LBZ/LMM harness laying around with Black injector plugs they would sell?? I have 2 sets with gray, but only 1 set of black. I don't recall which was came on which model, but want to uae all black.. Sent from my SAMSUNG-SM-G890A using Tapatalk

    It works perfectly with no ill side effects. I do have a couple new connectors in a bag somewhere, might have the part # on it. Been a while since I ordered them. Typically I just reuse the stock connector and lengthen the wires. Sent from my SAMSUNG-SM-G890A using Tapatalk

    Also wrapping up the closed loop cooling systems. Had a few temporary hoses we'd cut up to make things work on the dyno. Was time to replace those with the hard pipe. Added some extra clearance to fit an old school oil pressure safety switch, that will control the lift pumps.. Sent from my...

    Twins with Twins, Anyone?

    This week's projects. Plumbing PS, a little differently than most. Have two pumps / engines, and only one pump resavour. Rather than mount the tank on one engine and have a crossover line always in the way, I'm mounting it 6' away. Which opens ya up to air locks in hoses. Unless ya mount the...

    LML Callies Durastar Crankshaft Issues??

    Thanks for the update Gabe. Have they Rockwell tested the surfaces in question yet? As Stingpuller posted above, thrust washer failures are not that uncommon in pulling applications with big spring pressure plates. My neighbors BBC truck ate a couple every season till he sorted it out...

    LML Callies Durastar Crankshaft Issues??

    OK I'll bite. Show me another crank manufactures example with same point of failure then? Educational, but irrelevant unless you can reproduce the issue across the board IMO. Sent from my SAMSUNG-SM-G890A using Tapatalk

    LLY: Fuel Return Circuit

    Working on custom returns this week also. Thanks for that Parker #. As for fuel temp sensor, suggest leave it connected to ecm so it thinks it's working. Just tape up in harness. I divert them and repurpose as Oil Temp sensor in boat builds. The ecm only uses the data to lower FP if temp...
