    L5P build

    What electronics will you use to run the engine? You should be able to bolt either a 6speed or a zf6 to it. What exactly was your question? Sent from my iPhone using Tapatalk

    Does the vane position sensor move at all if you monitor that? If not, remove and manually move the plunger and see if anything changes while you monitor it. I’ve never heard of anybody having much luck with Chinese sensors. Sent from my iPhone using Tapatalk

    Picture of my gauges. Early 15, and have the A50/T14. Did you code the cluster to the ECM/BCM? Sent from my iPhone using Tapatalk

    2015 MY trucks built before 8/14 had the A50/T14 TCM as pictured. 2015 MY built after 8/14 had the smooth case T87. The cluster you pictured must be out of a Chevy, because the pre-8/14 GMC clusters had red accent lighting, and this shows as green. Sent from my iPhone using Tapatalk

    CP4 diagnose P228C P228B

    Got some good info from a buddy that wrenched at a dealership. With the injectors unplugged, and cranking for 15 seconds, there’s isn’t supposed to be any fuel coming out of the injector returns at all. So we’re good there, I couldn’t even get a drop. Max return spec for regulator #2 and...

    Finally got some time this evening to check out the return rates for the injectors and pump. I know I’m a procrastinator, you don’t have to tell me. [emoji38] Here’s what I did, tell me if I did something wrong. Never checked return rates before. Pulled the rubber hose off of the last injector...

    trailer wiring

    Blue wire is the brake wire. The power wire should be either red or black. You need a constant power to the pump, and the blue wire will activate it. If you know which wire is your ground wire on the 7 way connector, the power will will be directly opposite it. So it you have negative at 1...

    2015.5 LML Coolant Issues

    Doubt it. I think the system is rated at 20 PSI. You’re not losing it very fast, so you’ll probably just see some drips somewhere if that’s your issue. Sent from my iPhone using Tapatalk

    2015.5 LML Coolant Issues

    First thing I would do is do a coolant system pressure test. My guess is there’s a very minor leak somewhere, and it’s evaporating before it hits the ground, and so you don’t see it. Sent from my iPhone using Tapatalk

    LMM: Mystery Coolant leak

    Easiest thing to do is put a pressure tester on it. Borrow one from somebody, or loan it from the part store. Sent from my iPhone using Tapatalk

    Yeah, brand new filter when it started throwing the codes. I’ve got a snap-on scanner, that was the next thing I was going to try. Probably will be this weekend before I’ll have time to mess with it tho. I’ve heard of a few. Dad’s went out in his L5P @ 30-40k, had the whole fuel system...

    My thought initially was also that the injection pump is going out. Injector balance rates all look good. Measuring how much fuel is returned during 15 seconds of cranking only tells me if any injectors are leaking, right? Sent from my iPhone using Tapatalk

    Kory’s tunes. Truck is 2017 with 315k mikes on it. Truck was tuned at 250k. Tow pig, right around 26K gross. I’ve got an edge monitor in the truck, and always watch the desired versus actual. Run I-77 north and south a lot, and run the WV hills pretty hard, that’s why I’m surprised it never...

    L5P performance builds (beyond just a built trans)

    There’s a diesel shop out in Wisconsin somewhere called Diesel Attitude that swapped one into an LBZ. Don’t know if they’ve done anything modification wise, but they do sled-pull with it. Looks to be running great. Sent from my iPhone using Tapatalk

    LLY Intercooler - CSF

    The OEM+is as bout a 3/16” narrower than my stock one was, at least for the LML. I blew it apart pretty quickly, but I put a lot of boost to it. I’ve got the HD now, but the truck has sat all winter and don’t have very many miles on it yet. Sent from my iPhone using Tapatalk
