T87 Swaps
If you have any ways to capture raw canbus data, csv format is good. Would like to compare the 2010 ebcm and bcm data to others. Just now happened to find what looks to be a 2010 bcm in a box of parts. From what, I have no idea. But the more we know about each Hardware and OS, the easier it is...- kidturbo

That's some great info. Thanks for sharing [emoji106] I was gonna start looking for a later LMM and early LML truck to test drive. If we can get the ABS happy, the BCM stuff shouldn't be a huge deal either. So far, I've been going off 08 LMM recordings, 17 l5P, and a 16 LML ecm stand alone...- kidturbo

T87 Swaps
Did a little digging this evening on what our T87 expects to see for Input and Output speed signals. First off, I also verified the # 19302667 is used on gassers to at least 2020, by just looking up the speed sensor for a 2019 Tahoe. Everything comes back as 19302667... So that's interesting...- kidturbo

Gonna leave this one up to the knowledgeable transmission builders on here.. From what I have read, and seen with a volt meter, both of these new speeds sensors are a 9V Hall Effect. The pins on TCM output 9V, and I'm not sure what the return signal actually reads yet. If someone has a good...- kidturbo

Also making progress on the 80 pin connector. Outer shell is fitted. Took a few attempts to get the fit I'm told. But I have a young and eager Engineer student on it. With a bag of assorted pin terminals, some good software, and a couple 3D printers. He's already surpassed my skillset, so...- kidturbo

Discovered a slightly BIG freaking issue with sticking this T87 into the 2005-2010 truck chassis. While we can make the TCM speak happily with the E35A/B ECM by tagging on a few missing packets of required data, that can be assembled from existing CANbus data, the TCM really doesn't like any...- kidturbo

A couple things I do notice missing from our 35B ECM traffic, are packets that carry Transfer Case / Driver Mode Switches [IE:TowHaul] and from our LMM years BCM is Tap Shift Data. Someone please refresh my memory on how Tap Shift was handled back then. TowHaul is actually in a ECM packet, so...- kidturbo

Did a little more bench work last night, and was able to satisfy all the missing Comms DTC errors. Running LMM ECM along with my crank/cam emulator, and a CANbus gateway substituting the missing data parameters. Similar to the E38 approach, but with actually less data required on this Allison OS...- kidturbo

Chinese FICM
China can certainly crank out boards like shit thru a goose, but I'll bet ya they ain't setting on a stack of those aluminum backplane assemblies.. Ever take a close look at one? Somebody, likely a human, had to weld every one of those 2 piece assemblies. -

Sure sounds like a sniffing endeavor, doesn't it?? Time to check the FB pages for chatter. Sent from my SM-S901U using Tapatalk
