Here's a link to a couple.. https://mega.nz/file/875UETTD#mNWdSgTbk ... a3MILA33-o

I can zip up and maybe post up individual bins here but size wise I figured this is easier..

Re: need something quick and dirty

Need to know the vehicles and ECM's used for the seed and key routines.. Sorry but it's not quite quick and dirty.. If I know what ecu's your needing and/or the ecu seed key algo I can write something up for a couple ecm's but I am honestly kind of busy and it'd take me a bit of time to find some sp...

Re: E92 PCM Reverse Engineering

I can and I'm sure others can give it a try on a bench E92.. For writing I am using the factory sps format and the aftermarket's appear to be doing the same.. In any case if your writing your own I would stick to doing something in the calibration section as if it does get bricked it can get fixed w...

Re: Vpw gm class 2 stop lamp message

90% sure you need to put some sort of a resistance load to gnd on that ckt. If you measure it you'll probably see some sort of reference voltage close to 12v.. It sees it as released when the voltage is brought near 0 volts when the brake lamps are not powered and are instead providing a path to gro...

Re: cooked eml327 ? After attempting to change the baud rate

The problem is likely that the USB to serial chip isn't capable of 500k.. Check device manager and the USB to serial adapter properties and see if 500k is an option.. Also if you take it apart and ground pin 6 you should force 9600 baud. This would allow you to communicate and change pp 0c to someth...

Re: cooked eml327 ? After attempting to change the baud rate

How are you connecting the elm? Bluetooth? Wi-Fi? USB? Serial? If it’s a USB elm check the device manager and look at the com port and properties and settings to see if you can up the baud to 500k, see if the usb ti serial chip is even capable of that speed. If it’s Bluetooth, not gonna be fixable u...

Re: Need help with understanding opcode failure

I think you may have set the calibration file as 03 instead of 02. so in step 0x14 the program will look for 02 but there isn't one. Damn it, I missed that!!!!! I saw the file had 03 internally but incorrectly assumed he set up the archive correctly since I saw the files in the correct order.. how ...

Re: Need help with understanding opcode failure

So, .... You can program the module with the OS and calibration files using sps2.. But the vin is wrong since you want to use it in a different vehicle. Could make a utility file to just write the vin, but.. Could take the utility file and modify it to jump to the second stage(This is where it would...

Re: Need help with understanding opcode failure

Where did you get the files? Can you post up your vin or pm it so I can check cals.. Quick internet check shows those as valid cals for a 2010 2SS though.. It is weird that it's not even showing it exiting with error or even showing it attempting to send any data with the B0 command. It wrote the OS...

Re: E92 PCM Reverse Engineering

Someone who knows more than me will chime in but to send that 00 00 01 01 fe 3e You need to have extended addressing turned on..
I've messed with it but since 90% of my code I've just used raw can I can send whatever I want including that message but it does take more work in the end I suspect.
