    Tow/Haul mode, LMM Swap in an 84 C30

    Thanks man! That was the goal with this project. I want to have a factory reliable tow rig that is a good mix of old school cool and modern technology.

    Tow/Haul mode, LMM Swap in an 84 C30

    Thank you for asking about that for me! Greatly appreciated man! Thank you man. I think at this point I'm going to concentrate on trying to get the BCM to work. There has to be some kind of power, gnd or ign input that I missed. Sucks working without a schematic of this thing.

    Tow/Haul mode, LMM Swap in an 84 C30

    Lmao! I'm kinda thinking I asked him if he could make tow/haul mode in the trans work on one of my dsp5 settings. I'll check with him again. Thanks man. I really appreciate the offer. I'm pretty sure I just need to iron it out with him. I'd imagine he can do it for me. I'll ask and...

    Tow/Haul mode, LMM Swap in an 84 C30

    I did not build it myself. I used a guy named Ken Wolkens at Standalone harness. Thank you a ton for the offer man! I don't have efi live. I used a local guy that did my tuning for me. I asked him about it before, but I thought he told me he couldn't flash the tcm. I could be mistaken...

    Tow/Haul mode, LMM Swap in an 84 C30

    Thanks Harbin22, but for that to work I would need to get my BCM to work in my standalone setup. So far that doesn't seem to be my strong suit... lol

    Tow/Haul mode, LMM Swap in an 84 C30

    I didn't think you could do that with efi live. I was under the impression that it only flashes the ecm?

    I guys, Just wanted to drop in and introduce myself. I'm building an 84 C30 dually with an LMM and Allison. She's gonna be a tow rig for this race season (drag racing). It's a static lowered crew cab dually with 19.5s, load range G tires and a rear from a 2005 3500hd. So far everything is...

    Tow/Haul mode, LMM Swap in an 84 C30

    Hi guys and gals. I just built an 84 C30 3+3 dually with an 08 LMM/Allison. It is a stand alone harness and I have the original bcm from the donor truck. I am trying to get tow/haul to work by adding the bcm back into the swap harness and so far it's been a rough go at it. Has anyone tried...
