    T87 Swaps

    Saw this ad today, and gives a bit of insight to unlocking. I'd heard this before, but looks like tuning requires a bench harness. Another think I noted about these T87 units, they actually have 4 CANbus channels in the hardware...

    T87 Swaps

    I've inquired about that one for ya. On the T93 it's seems to be about GM going to the Global B platform. However I guess HPT has that sorted now also. The whole unlock deal is a big hush hush, with only a few people knowing how to do it. Thus making the most of it. I hear the best source of...

    I'd also really like to compare with the bin I currently have. How many releases did they start with? The 87A development traces back to at least the 2013 time period, which tells me the T87 started a good 2 years before, if production releases followed along similar timelines. My rev starts...

    Did some reading, and stumbled across the thread you referenced @Cougar281. Looks like BT spotted that sensor difference back in 2017. However he never mentioned possible options or workarounds. It's not real hard to convert analog sine wave to 0-5v square wave. Found some simple circuit...

    Thanks for the link Ron. While I didn't find exact pinouts for both yet, I did stumble onto a thread where ATS is saying you have to change the turbine and output shaft speed sensors with their conversion kit. So guess I'll need to do a little more experimenting with this T87 unit and my old...

    Once ya get em out in the wind, grind on em a bit, solder will stick.. Look brass under the tin.. Sent from my SM-S901U using Tapatalk

    Pins are to strong to be pure aluminum. Yet have a weak magnet attraction. Some composition, copper nickle maybe. Ok part 1 done, where do all these wires go now? LoL Sent from my SM-S901U using Tapatalk

    80 Pins, the old fashion way, with Buffalo Bill skinning job.. lol P.S. 100% two piece design with header plate and pins slips into the frame..

    Sounds better than my idea of a mig wire, and some heatshrink.. I'll send ya good one to play with tomorrow. With camera zoom I can see some sort of wire remnants stuck on these pins. But it's sure not solder.. Sent from my SM-S901U using Tapatalk

    My innermost Ted quickly discovered, this is a 2 piece assembly. The pins are cast into a header which slides into this outer frame. Now getting it back out might be interesting. Let's see what they used for glue. Is that center pin for a puller?? [emoji4] Sent from my SM-S901U using Tapatalk

    T87 Swaps

    Thanks I'll keep that in mind when I drop one of these off to my soldering guru tomorrow.. The first attempt with my pitchfork size soldering iron, resulted in just melted plastic. Scuff and Flux did me no good. But I recall watching a video that explained how these were spot welded...

    T87 Swaps

    What I am doing right now.. I also just verified your previous shaft speed sensor comment. They are different on the later model Allison, and not interchangeable in the case. So we may hit a hardware cut off, where we would need to read, and retransmit as correct wave to gap years. Won't know...

    Thanks. I hope to do him proud. Seeing all these different revision numbers inside these junk cases, helps one understand how many times the head engineer had to realize, his grand design actually sucked.. Sorta like when my GM tech buddy would send me pics of the latest Rev# on CP4 Pumps...

    Ok now that I have some hardware to play with, who's willing to help me pinout these puppies to the T87 ??

    Never hurts to ask... Think these guys could use a FICM / Bosch style header to resolve 50% of these TCM failures. Allison would just chit if we redesigned their hardware too.. LOL Simple offer to share ideas is sometimes all it takes to work towards a common goal. Tell ya right now, won't see...

    Big shout out to the SC based team at circuit board medics for sending me some T14 scraps. Because one man's junk, is another man's treasure.. Have enough cases now to build a couple of adapter cables, and still send some off to China for reverse engineering.. Had no luck reaching anyone at...

    Yet... I haven't played with this 2020+ junk enough to know if it is readable, after an unlock or not. Might be lml setup, where need the bin to start with.. Or pop a chip to get it. I'll certainly enquire for ya. Sent from my SM-S901U using Tapatalk

    To clarify 87A bin is for Allison, while T87 on bench is from a gasser. I have found 1 canbus ID used by this one, but not listed in the 87A bin. So they are very close in GMLAN language, but I've yet to be able to import this bin to EFI to view tables and compare. Pops a msg, saying doesn't...
