    2027 more emissions....

    For hydrogen, not just a good storage solution as it loves to leak past everything. But also a means of extraction that is energy efficient. Right now it takes more energy to get hydrogen then hydrogen provides. Plus the issue with most hydrogen coming from petroleum or petroleum sources. Then...

    2027 more emissions....

    Yep The output of the generator on the other hand I think is in the range of 480 to 600 volts. Apparently one was used one to power a small town. I still haven't figured out how voltage and frequency matched up so perfectly unless they also use 480v 60Hz 3 phase as a standard.

    Yeah, the beauty of electric motors os that you can keep the same torque throughout the whole RPM range if you raise the voltage at the appropriate rate. Or you can keep the power (HP) the same which would have it's peak torque right off 0 RPMs. ICE's, even diesel doesn't come close to this...

    This guy put a generator in his Tesla First test with a smaller gasoline unit Source: https://youtu.be/hHhf223jGIE He then installs a little diesel. But it's full of issues Source: https://youtu.be/seHWJMKwOQQ Source: https://youtu.be/5Qu-BDixGYY I think it would be a lucrative...

    Pat started a thread back in 2016 with very similar discussion about making a hybrid https://www.duramaxdiesels.com/forum/threads/ev-powertrains.71366/ Not sure if it's worth migrating this topic to that one or keeping it here

    2027 more emissions....

    That's my understanding too. Same basic setup as a diesel locomotive. I think they have a battery bank in theirs though The issue with using this strategy for vehicles is the efficiency. Too much losses from the ICE to generator then electric motor. A hybrid like this might actually net worse...

    Bought, wrecked, rebuilding a 2009 LMM

    If I'm reading the circuit right, there is two sources. One from each stud. One for the 7 way can be split further up towards the cab into a second in the bed power and the second stud powers the trailer brakes on the 7 way. If you check the power on the three. I wouldn't be surprised if you...

    2027 more emissions....

    Exactly. I've seen a few studies on the cost to own an EV and in order to make sense.ypu have to change at home for something like 10¢ a KW to break even with gasoline prices. That doesn't even take into account the increased cost to purchase one. If you have to use a charging station then it's...

    LBZ GPCM Issues

    I believe it's labeled ignition 0 But if it's blown or bad your engine shouldn't start as it also powers the ECM. But should be the same line supplying the power to the GPCM

    2027 more emissions....

    If only we could have a movie grade power source that could power our EVs for a minimum of 20 years before recharge or replacement. Going to have to be some major improvements in battery technology before they can replace the ICE

    Bought, wrecked, rebuilding a 2009 LMM

    Should be one coming from each stud. So two. Then depending on your RPO options one might split for another camper power wire in the bed. That might be why you have three. But I'd trace them out to be sure. Should be easy to remove or attach the ring terminal to the stud and see what gets power

    LBZ GPCM Issues

    Welcome I'd be probing for power and checking the serial data lines. If I'm not mistaken, the ignition power feeds the ecm ignition power as well as the GPCM. Verify the fuse and power through the ignition to the GPCM is good. Then prob the serial data lines. Should be 60 ohms. Two 120 ohm...

    2027 more emissions....

    The MPG dor diesel vehicles as been pretty stagnant for the last several decades. While gasoline vehicles see steady improvements and now set close to or even exceed diesel in some aspects. Since this monstrosity of an emissions system is really only effecting people who drive diesel. There is...

    2003 Duramax - sputtering

    If you don't have the equipment to diagnose or even just get us the information it's going to be really hard for anyone here to provide any meaningful help. So, as tom said. Best to take it back to the shop. Or maybe another shop who might be better at finding the root cause

    2003 Duramax - sputtering

    Any codes? Your going to need to get use some more information. We need balance rates, main rate, desired MPa, Actual MPa, missed cam & crank counts, Maf and Map readings. And maybe even timing at idle Is the engine tuned? Lift pump?

    2027 more emissions....

    Yeah, I'm not sure why some do it and some don't. Can't be all emissions components because my LMM will smell sometimes. With or without the DPF in place. DOC installed. So can't be that. My LLY doesn't seem to have that problem. Has EGR and DOC. Maybe it's mostly effected by tuning. Might...

    That last 5" downpipe exhaust I purchased had the pipe right at the fitting neck down so as to fit a standard sized downpipe. I would not be surprised if that one was the same.

    Help!!! 06 lly/lbz Allison 1000 6 speed clunking

    You might not realize this being new here but he is the Almighty staff member. Infact, he owns the forum. So, best not poke the bear of you want to stick around. You are pulling on a very short string.

    Anybody drag race with an lbz??

    Definitely looks lazy in the 60 and 330. I bet with a good tune, proper suspension and tire setup you can knock a second off that time. Possibly a smidge more. But you're going to have to do a boosted launch
