    6 Speed Valve Body Question

    Hi guys, here is a question for you transmission pros. When shifting a 6spd Allison into manual mode, is there actually a different position in the valve body section?? Reason I ask, am helping a friend with a 6spd in a "no torque converter" marine conversion. Currently he only uses shiftier...

    HS GMLAN Gateway

    Think I finally have all the bugs worked out of the gateway. Still testing the GPH fuel burn rate calculations, but the rest seems to be working correctly. My buddy Dave is currently beta testing one on his twin turbo Duramax boat. Couple tricks we used to get all the must have PID to display...

    tuning question

    I wrote a lope into a dsp position on my boat tune just to see what it would sound like. Pipes under water at idle, so it was pretty lame. Did make the wife say "what's a mater with the engine?" Directly followed by "Stop It Now!!" :rofl:

    Yes the multi-display LMF-200 & 400 units would be a great fit in any conversion because you can lay out a couple of them in a small area. Monochrome, plus they do pop up alarms for things like temps or low oil pressure. However they need to be the newer Lowrance units for true N2K...

    Update Got most of the GMLAN data displaying in NMEA/2000 plotters this week. Still fine tuning a couple values and beta testing on a friends Dmax boat. But here is the final breakdown. ECU - Value ECM - RPM ECM - Oil Pressure ECM - Fuel Level ECM – Engine Temp TCM - Gear Position as...

    Push Button 4wd in my Swap

    Humm... Good questions. From my hacking on the LMM's I don't believe the lack of BCM or DIC is your issue. You obviously have a good data link since the TCCM is responding to the SnapOn tool. Have you done the transfer case position relearn with the SnapOn tool? That fixed a friends truck...

    HS GMLAN Gateway

    Just checked the DTC list in a customers LMM tune and swear every other engine circuit down to the AC clutch was listed. But no EOL. Strange. Like they wrote it out or forgot it.. There was however DTC settings for oil pressure sensor, along with my new favorites, the MIL circuit failure, and...

    Was that also a LMM that set the light with EOL disconnected? If so I'll retest on a bone stock truck without any tuning. Possibly a DTC's disabled, will have to look into it. Found many differences between the LB7 to LMM relating to DTC options. Like an LB7 will never limp on low fuel...

    HS GMLAN Gateway

    Ok I'm done logging CAN data... Not cause I've achieved everything I was after, but rather cause I'm done trying to think like a GM engineer. :violent: I've stumbled onto some pretty interesting Duramax quarks over the last week worthy of further review by anyone who owns one. 1st, has anyone...

    Think I finally found the rail pressure PGN. Matches up pretty close with Dmax MPa scale, so will add that one. PID 164 - Injection Control Pressure update rate: 1 time/s resolution: 1/256 MPa (Uns/I) source: Injection Pressure Sensor On secondary shift...

    LML Marine swap

    What I heard also Joe. I spent a few hours logging data off my buddies truck last week, and IAT was in the 50-60f range most of the time. Several big HP engine builders (on the marine side) have adopted this Yettie cooler design atop the intake runners. First one I recall seeing was on the late...

    LML Marine swap

    Been following that new build for a while. I heard the Cummins powered Vee used for Bermuda run is setting out at LOTO. Where it's been for sale since last year. Anyone else think they are shooting a little high on HP goals to expect more than a few hours wide open running on Dmax blocks...

    LML Marine swap

    Yeah the old Doug Nash units off a 4+3 Vette were kinda what I was thinking of using. The next version was used on 80-90's Dodge trucks with that push button tail shaft overdrive. Those should be pretty common. All them are a simple cone clutch with a planetary gear set. Fewer moving parts the...

    LML Marine swap

    Correct prop shaft speed is the key to speed. Let Mr Smith or one of the old school Diesel racers from OSO explain this important fact better than I can. 3200 - 3600r is like the sweet spot on a Bravo setup. If you go Arneson surface drive, you can go bigger dia prop and lower that range some...

    HS GMLAN Gateway

    Engine load calculated. Same as you'd see in EFI or other tools. Yes they are basically the same thing. But OBDII protocol is slightly different from high speed GMLAN. You have the OBDII specific rule set that fit about any car out there. Used in apps like Torque. Then you have this other GM...

    HS GMLAN Gateway

    Tow Haul on/off was actually one of the first CAN messages I isolated. So guess we just need to find that matching display PGN for the J1939 output side.. Anyone with industrial equipment experience happen to know what those display tow haul as?? Am certain Allison used a specific name for...

    LML Marine swap

    Headless, my personal opinion on a SC after considering it. Besides the crank issues, one charger won't feed it. Banks did a SC with twins, and I believe a member or two here have similar builds. While I've seen videos of both those Banks setup on a dyno, someone please show me one in a boat...
