T87A Bins to Pins - Who's In ?

[kidturbo]

Tested the U-link CANbus read/write with custom kernel functions. And it works. But I was having issue getting it to load some OS versions. Then I loaded a virgin OS Boot software part number: 24288837 and that allowed full read and write on my properly terminated bench harness. Along with a bit of tech support, found the cause listed in the video comments. We need to help combine these OS differences, into a single T87A custom kernel.
For now, Important>
"If your boot block is 24288837 you can use TCUT87ACAN. If your boot block is 24284338 or 24272182 you need to use TCUT87ACAN1 or you cannot enter DEBUG ON. You can also upgrade your boot block to 24288837 independent of what the rest flash is."

With a little code work to hush neighboring bus traffic, I believe this custom kernel option could handle SPS level segment full or cal flashing over OBD2 port same as all the big tools. Uses OBD2 commands, and doesn't seem to require any special pinout, or care about being wired to transmission. So once it hits the bus, all just 1's and 0's again anyways. Much potential..

Well said.

i had entirely forgot that i had purchased 2 of the u-links since i had never got around to opening up an e38, so they've been sitting in my desk drawer at the workshop.

As i have an E38 that would get hot and do wierd stuff in a car & was fixed by replacing it, I have a good candidate test opening the case on.

Got me wondering if the global-b E90/9 unlocks are on the cards in the future?

well I spent $640 on ebay by ordering an e90,t93 & t87a. for when i get around to doing something with a 10 speed & L87 engine in the next few years...

Sorry, I've been busy breaking the T87A six ways from Sunday. Not sure why yet, but am finding some weird stuff happening between different 10L OS. Like one version drives and shifts normal, next one goes from 1st to Neutral. All in same stand alone environment, receiving same CANbus data. Turning off certain DTC's, might actually cause new unforeseen problems. It's certainly been a time consuming little unit. Happy on the bench, pissy in the car.. I believe there's some hardware specific data hiding outside our normal SRAM reading range. Might worth exploring. That and some OS related unlock issues still need resolved on these. So jump on in..

On the T93's. I have one cracked open, but haven't isolated which pads are which on the JTAG. However, I have learned they are being unlocked by reflash using CAN FD mode. So another new tool on the way.

my ecu/tcm's arrived while i've been away for work, along with the can interface module to do them. I might have a play while im home.

Also found a place that sells a 10l80/90 to tcm harness for $110usd. gonna have to send them an email as they don't list international shipping.

edit v2. come across this tonight.

Cheaper then trying to get a 6l80 setup done as i have transfer case and all the front diff setup already.
