    T87 Swaps

    I have the stock tune read out already with EFI live, but my laptop went for a swim. If I get my info pulled off of it I’ll have that before Monday.

    anyway to unlock efi live tune

    Maybe I’m not following correctly but if you have a 6 speed conversion, even if you have the tune file unlocked. If you’re using EFI live you will not be able to make changes to the 6th gear. 1-5 you can change

    T87 Swaps

    Okay I may be crazy. But I’m pretty sure I seen a 15.5 LML with an A50. I thought all 15.5-16 had a T87 and I went to cal flash without reading the tcm first and got a error on EFI live. Thought that was weird. Went to install the DSP5 pins into the ecm and looked at the tcm and it wasn’t a T87...

    Pat and Kat used to use tow bars. IIRC they mounted where the tow hooks mount. You’d also need to buy the brake assist thingy that goes into the tow vehicle if you wanted to be “safe”. But a trailer might be a better option

    What did I get myself into..

    I used sound skins I can’t remember the exact spelling but it’s like dynamat but it has a foam like layer on the top. Started with the doors and it made a huge difference, then did the back wall. I noticed a huge reduction in tire noise and it made the speakers sound better.

    TCM, Dashboard, and OBD2 Power Issue

    Could be the connection at the OBD II for the edge or the edge itself.

    Where did you get injectors from? Is fuel pressure following desired? FPRV?

    Truck mania

    The front diff may or may not have a hole in it still. And possibly needs a torque converter 😳 But The Black Mamba should be there.
