Re: E67 to T87/T87A TCM interface needed
Am I the only one that has the popcorn out watching this? Genuinely excited watching the progression! I see its fairly easy to find the RXD/TXD header bytes now. Is there an easier method of finding all the support mode commands (ie.. 1A, 3B, 27, 34, 37 ect?). I have always had trouble trying to lo...

Re: E67 to T87/T87A TCM interface needed
Small update, flashed ecu & tcm just now. SUCCESS! Dash cluster now reports PRND position changes. Now to see if I can get VATS security to work on this OS. I've had to disable it on 12609099 to get it to fire up. Nice work. From what I've seen, you are on it 100%. :punk: I always felt there sh...

Re: E67 to T87/T87A TCM interface needed
Good info. I'm not sure what GM actually called this second set of HS GMLAN ID's, but it would helpful to categorize what PCM hardware OS versions ran it. For now, at least ya know what your lookng for in the ID structure for anything in question. If CAN ID's are all dec, it's Corvette / Holden ver...

Re: E67 to T87/T87A TCM interface needed
That is an interesting piece. Not a complete body control module, however it has 2 pair of canbus wires. GM had a tendency to do that with a few modules like the TCM's. Basically they were just daisy chaining some the nodes together to save wiring. However for that PIM module, I would like to see wh...

Re: E67 to T87/T87A TCM interface needed
First interesting thing from your 2006 E38 file is our 0x0C9 ID. In your capture it's 8 bytes long, but in most of the US versions I've seen that is only 7 bytes.. That last byte is Boost Pressure. " C9","8","00 00 00 00 00 40 08 00" I need to dl the software to view t...

Re: E67 to T87/T87A TCM interface needed
Couple of logs from a Holden VZ, this was a 6 month model run back in 2006 prior to the release of the VE model (later exported as the g8 in 2009). They had E38/T42,ABS,PIM module on the canbus. 1 log is key on, engine off. 2nd log is engine running & me moving the shifter through P,R,N,D etc (...

Re: E67 to T87/T87A TCM interface needed
If I counted correctly this is where bytes are stored from that message, r31 is the offset they get stored in numerical order. Now tracing down to individual bits will take some time, due to ppc crap code. Here is how bits are copied for first byte , r4 is the bit position, some bits might get inve...
