GMLan Bible updates

[ghodge]

It was delivered this morning. The case is anodized aluminum when I was expecting plastic. I need to sort out the capabilities of the internal Bluegiga BLE112 module for my bluetooth application. I need it to support the HID profile but I'm not sure it does.

[TazzI]

Yeah I read about the nice aluminium casing. I saw that updated with black and blue cases just yesterday I think.

What are you aiming to do with the bluetooth? Apple integration, android integration?

Pitty shipping takes so long to Aus!

The cool thing is it supports three CANbus interfaces so plugged into the main OBD port I may be able to simultaneously display engine parameters on the DIC as well as control music with my iPhone. I can see this working with Android as well.

So keen

Whats up guys? Any one get tx running on the can bus shield/arduino set up yet?

Hi guys, new member but long time EFI modder. I see some of you have recently picked up the new CBT to play with. Glad to find other skilled users. I've been fairly happy with mine, while the code improves.. Haven't gone much beyond data logging, since I lack good Arduino skills. But am pretty handy with EFIlive if anyone ever needs help.

What I have been working on is a high end gateway that does high speed CAN-2-CAN translations for engine swaps in performance boats and other vehicles. PCB's completed and currently on the 07 and up LS and Duramax HS GMLAN protocols. Rather than use a OBD PID request method to pull gauge data, I've been trying to reverse the HS data that's streaming to the BCM for translation heading to the low speed IP cluster. How I landed here.

Another site I found listed 105 known 11bit HS GMLAN ID's.

096 097 098 0AA 0B1 0B9 0BA 0BB 0BC 0BD 0C1 0C5 0C7 0C9 0D1 0D3
0F1 120 12A 130 135 137 139 140 148 160 17D 182 185 186 1A1 1A3
1C3 1C4 1C5 1C6 1DF 1E1 1E5 1E9 1EB 1ED 1EF 1F1 1F3 1F4 1F5 1FB
200 202 204 206 214 222 224 226 228 230 236 238 287 2C3 2C7 2F1
2F9 32A 348 34A 3C1 3C9 3CB 3D1 3DC 3DD 3E3 3E9 3ED 3F1 3F9 3FB
3FC 451 4C1 4C5 4C7 4C9 4CB 4D1 4D7 4D9 4E1 4E9 4F1 500 514 52A
530 589 770 772 773 778 77D 77F 787

These are what I've verified streaming from the 08 Duramax ECM so far.

3D1 Byte 8 Accelerator 00= (0%) to FF = (100%) [A*100/255]

1F5 Byte 4 Shift Position PRNDL 1=Park, 2=Reverse, 3=Neutral, 4=Drive, 9=Low & M1, 8=M2, 7=M3, 6-M4, 5=M5, 4=M6

Byte 6 is Tow/Haul Status 4=ON, 0=OFF. This set changes when in Manual Mode to 2 & 6.

Bytes 1,2 need further research.

3E9 Bytes 5-6 Speed 1/100 MPH 55MPH would be 5500 (0x157c)

4C1 Byte 2 Engine Temp in C. [A -40]

Anyone know where I might find info on the others?

Apparently this isn't being worked on much, if any... But I thought I'd share here anyway.

I've recently bought a 2011 Camaro, so like all my previous cars, I started hacking the CANBus on it.
So far this is what I've found on the single wire bus:
https://docs.google.com/spreadsheets/d/ ... sp=sharing

If anyone has any additions, I've love to hear them!
So far, none of the arbIDs in the bible (apparently for a G8) match anything on this chassis. Though conversion factors seem to work...

Hey everyone.
I was directed here from the GMLAN bible. I was searching google for a collection of GMLAN IDs and found "the bible" then I ended up here.

I have a Kia Sorento SUV with an Ly6 6.0L V8 and 6L90e transmission. I was trying to find information on the tap-shift messages. I unfortunately dont have a BCM from the donor vehicle so i cannot use the tap-shift without it. I am hoping to use an Arduino board to send the up-shift and down-shift messages to the transmission to allow me to have tap shift.

I am confused about the GMLan Bible posted in this thread. What make model and year does it cover?

What I want to find out is if there is a different document for say a 2014 VF Commodore.

I thought this document is for a VE Series I. Does it also apply to the Series II? I can't find where the application is specifically stated.

Hi, thanks for such an awesome spreadsheet! I have been working on some CANbus hacking for My Australian Holden Astra 'K' Series. I'm trying to automate a couple of things like automatically disabling the Start/Stop Eco function and a few other things.

I've been collaborating information between your data, other data users have sniffed the bus and my own data collection.

I was looking through someone else's data and they only reference the ArbID - For example 0x106 so when calculating the full 4 byte ID using binary (So I knew what to transmit), I was using your spreadsheet to verify the data as a cross check.

However, what I have noticed is that the Spreadsheet incorrectly displays a code of 0x1020C040 with an incorrect arbID of 0x16 and not 0x106. It does not allow for a leading 0 in the case of the final (first..) 8 bits of data totalling 'F' or less.

But seriously - Well done!
