More canbus accomplishments.
So ive been working on a program for which you can port live information into a log file as well as a real-time display of parameters. After hammering the ins and outs of python, ive finally achieved a working model to build off of. Ill be releasing the source code in the coming future. Enjoy, and much more to come.

Well a long while back, the goal was to simply adapt a standalone into the car. At that time i didn't entirely understand canbus systems and their in's and out's. So I got to researching and that worm hole led went all the way down to programming and software that's applicable for researching canbus systems, after playing with linux and a utility package and then buying into 1350 software that doesn't do half of what they claimed at the gui level, i went back to the drawing boards and social networking. Tried the microcontroller options, but they're inefficient for quick development, made a full circle back to Linux as it's an open sourced option I felt more confident in than anything else and I don't/didn't have the desire to get burnt again on software options that underperformed. So for the past few months, I've been focusing almost exclusively on learning a couple programming languages that allow me to accomplish my goals, and now I have a decent working model and proof of concept that I am capable of interpreting signals on the canbus network vs just saying I can or showing some raw data types. I'll be working on yet another personal utility that I may not be releasing that will be used for bridging 2 canbus networks together to modify data from network to network. And then Ill actually work on oem integration of a standalone system on the car.
If the money for this platform was heavily existent for the objective, it's possible I'd have a bigger fire under me to make progress quicker, but for now I maintain a 60hr /wk work schedule and work a little bit every now and then directly on the platform. But for the most part I've been working on tools for efficiency vs directly on the reverse engineering of this car. Think building a car to drive vs simply getting on a horse and riding

Keep up the good work Mitch. I know you have been working on this for quite some time and in the end im sure it will pay off. I look forward to seeing more progress.

To fully integrate a standalone ECU into this platform is a massive undertaking. Speedriven/Syvecs have never finished their project. Maybe you’ll be the first one. Well done for trying.
Me, I’ve just wired up an ECU and worked around the bits that caused conflicts. Auto gearbox became manual, digital dash replaced the original speedo. Luckily for us, the “marriage” of the engine ECU with the rest of the vehicle in this platform is much smaller than in modern cars. Due to age of course.

Good work. FYI you really do not need that much live data to do what you are doing. The bigger issues are the handshakes from different computers. Some care more than others. There are a lot of on/offs as well. A handful of toggle/parity sequences as well. Depending on what you want to work like factory. The torque reduction is going to be hard. ESP and TCM torque requests and the correct torque map from your ecu become fairly theoretical.
I did a similar project last year and the handshakes are what beat you up. I ended up setting the ECU to deny traction request.

312h is the main torque value. Static, effective, max and min. 212h has some response messages from ESP and TCM, and corrected. There is more. It is just spread all over the place. Take some of this with a grain of salt because most of what I have been working on is from Dodge. But most also transfers from each other. But not all. I swear that 212 is a TPS value in the Merc. Not tq. but I have never spent any time looking into it. It could all be driver demand though??

MBWorld Fanatic!
This is really cool to follow. More smarts than i have and patience too for something so time consuming and tedious. Good luck and hope you solve all you want.

Directly correlating to the E55 amg platform itself? No.
Between working on freelance development for various platforms (Lamborghini Gallardo, Audi R8, and Honda Civic), I've been focusing my efforts towards understanding ARM and STMicroelectronics HAL for building upon.
Needless to say, I sidelined the Mercedes development to build better tools to work with for overall Development. It's still my pet project, and will continue to be.
