I have an m66 ecm tune that I’m going to flash on first before I rip out the cem and change the params there

send me a .bin and tell me what needs to be changed in the configuration. I only need to change the gearbox from an AW55 to an m66, which I was planning on doing with Luke's CEM editor for the 2004 brick style cem over OBD2. I am now going down the path of using a ubsjatg to read the bin off of the...

Hey y'all, so I just read the flash off of my spare cem IMG_6140.jpg I got data off of the flash memory in hexadecimal, now I don't really know where to go from here. Do I need the entirety of the bin in order to crack the pin, or do I just need the security block, which in Luke's code as "read...

I'm not sure which usbjtag you're looking at but I just checked on there site and it's $65

Jeez, maybe I was looking at the wrong one! That sounds like a much more reasonable price. Im using the Seeed Studio XIAO, which is like 20 bucks for three. They're pretty powerful for their size.

Its far easier and simpler too use usbjtag to connect too the back on the module instead of removing the flash chip considering its buried and annoying too get too. As far as I know the usbjtag tool is cheap for what it can do. I was just going to use a microcontroller and use Luke's code from page...

Okay thanks sm. Luckily I have an extra brick cem to practice on.

Hey y'all Im new to this. I was reading through the thread, and it seems that the only way to crack a brick cem (2004 P2) is using an Arduino microcontroller and putting the cem on the bench. I then came across this on GitHub, https://github.com/mdapoz/volvo-cem-cracker which says it supports P2 20...
