    T87 Swaps

    Well I'm pretty good at tomfoolery.. :p I do have have the matching ECM, BCM, and emobilizer from the same 2016 vehicle. So guessing I could give it a shot that way and see how it responds. Probably looks at BCM for conformation. Here is the details pulled from this one. Happy Turkey Day 🦃

    T87 Swaps

    Ok ran into a small issue that might make me miss out on the cranberry sauce today. Attempted to load the 2015 Allison ctz file @Cougar281 shared with me onto this fine T87 unit, and that's a no go with EFIlive Ver8. Operating system mismatch between file: (24274899) and controller...

    It's already headed home. Plus he's down for a new board once tested. Not planning to put it back together until the spring. Sent from my SM-S901U using Tapatalk

    Repaired the old LLY boat harness this week. It was a bit crispy on the right bank when I cut it open. Melted injector 3, 5, and 7 injector leads together, and the connector off #1. So I was concerned with the FICM being damaged. Jason suggested I inspect the caps, and figured would be a good...

    Think we can deal with LBZ. It has a couple of IDs missing, but the majority of messaging is identical. Sent from my SM-S901U using Tapatalk

    The sensors wave swap is actually the easiest part. No code required. KISS is certainly the motto. Avoiding a packet firewall situation at all costs is the goal. Filtering and forwarding traffic isn't a terrible approach, if ya can get it right. OEMs been moving that way on the DLC as a...

    Solved the E38 msg bug today, and then cleaned most of the gasser stuff off my desk to make room for that T14 and E35B harness. A west coast friend with exceptional bin hacking skills, along with a few key words to search for, and he solved it on the second attempt.. No easy way around using a...

    T87 Swaps

    I've been messing around with trying to make the E38 talk to the T87 all this time. Ran into an issue requiring a cax file to be loaded into either the ECM or TCM to resolve a 1 byte length difference in a required canbus msg. Ya can't spoof an extra byte onto an existing msg... So now I'm...

    Took one of those T14 frames to my pcb repair guy last Friday, and ask if he could solder a wire to one of those pins.. 30 seconds later, he handed it back, ask what was the issue?? Issue is I obviously suck at it... Also wired up that little sensor fixer over the weekend, and it seems to...

    T87 Swaps

    After 72hrs straight, on about 10hrs sleep, I was finally able to isolate all the ID's this T87 gasser version requires NOT set a U0100 code. Admittedly, I may have slightly under estimated the CANbus requirements a few pages back... At least 8 ID's, each with 5 or more parameters, must be...

    Wow there it is... Many thanks. I'll send ya some Keebler fudge strips.. Now, did ya happen to spot the emobolizer?? Car still won't start for some reason.. Sent from my SM-S901U using Tapatalk

    That's exactly why I started with the E38. It's probably the original GlobalA ECM. All those ID's are still found in the E92. They just added a dozen more, and lengthened several existing 5-6 bytes, to 8's. But even with a full DBC file for GlobalA, it's still hard to track and understand what...

    I've misplaced my keyfob, and torn the whole car apart searching for it. If you can spot it, please let me know... LOL One thing I did misplace on purpose tonight, the U0100 DTC from this T87.. Finally stopped the little sucker from defaulting to it's brain dead tables. With a test...

    T87 Swaps

    More tools and hardware today.. Got us a clean working copy of the 2015 Allison bin for our T87. Was able to import it into EFI and convert to ctz. Now to see how easy to brick it... LOL. Thank goodness there are smarter people than I who've sorted much of these options already. The...

    Knocking noise

    My thoughts are tune table related. Possibly a change to fuel pressure, pilot injection, or timing that you are now hearing under certain conditions. If that is the change that brought on the noise, I would bring that up with the tuner. Doesn't sound like hardware issue to me.

    Thanks for the file @pl_silverado. I've identified the CanA and CanB canbus tranceiver chips and pins on the T87 board. https://www.infineon.com/dgdl/Infineon-TLE7250G-DS-v01_10-EN.pdf?fileId=5546d46259d9a4bf015a3ce3f8365e47 We have 8 pins for canbus on these boards, but only 2 CAN...

    Couldn't hold myself back from cracking this T87 open. Beefy.. Looks to have some test ports on the board. Sent from my SM-S901U using Tapatalk

    I'd have to crack one open to see where those pins actually go. But it's not uncommon to have spare supplies or Lo / Hi references for 5v sensors on most ECUs. There is also some 12v, and 2v pins in the "Unused" list in the diagram. And this is just what I discovered by some quick probing. They...

    T87 Swaps

    Since the time change didn't help with my sleeping disorder, figured I would sort out the pinouts between our A50 and T87 connectors. Some are easy, with matching circuit ID's, while others require some thought and wiring diagram tracing. But have a good spreadsheet started we can build on...

    Found what looks to be our read/write bit switch location in our bin file. Could be this simple to unlock, once we figure out how to write to the MPU over CANbus or by serial. /begin DATA_ACCESS 0x000000 /* ECU address type qualifier for Flash page...
