This video is a retrospective of how I got into car hacking, and how my project OpenVehicleDiag came to be, as well as what has inspired me to continue my work in this field. Happy #carhacking!
You also get to have a quick look at my #Mercedes #W203 in full, that I have featured on the channel over the past few years.
A huge thank you to everyone who's supported me over the past couple of years, allowing me to document my entire journey of car hacking!

This was the first time my #E55 #AMG engine fully died! - So I decided to document the repair process of bringing it back on the road, all whilst showing you how to save loads of money if this happens to you!
Let me know in the comments what you guys thought of this video!
Again, apologies that some of the footage was corrupted!

Just a quick progress update showing how I am probing solenoid operations of the stock EGS52 controller for my 722.6 gearbox. Doing this will allow me to mimic the same operations with my ultimate-nag52 gearbox controller which in turn will allow for super smooth gear shifting in the 722.6 gearbox with tons of configurability!
As explained in the video, I hope to have a completed controller in the next week, which would allow me to start doing the fun coding live-streams as we code the controller from the ground up!

Ultimate-Nag52 is designed to be a drop-in replacement replacement for the EGS52 transmission controller used in multiple vehicles (Mainly Daimler vehicles) for the 722.6 automatic gearbox, with full CANBUS support out of the box!
The aim of this project is to have a Transmission controller (TCM) which is powered by open source software and hardware (Teensy 4), and performs a lot better than the stock module, allowing for more adjustibility in terms of shift harshness, as well as using dynamic pressure modulation to fix some of the most common problems with the older gearboxes such as shift flaring.
In the near future I shall hopefully be streaming the assembly process of the first test PCB!

I messed up the code for my custom 722.6 TCM. This is the woes I get when drive testing sometimes!
What is happening here is the torque converter is locking up too quickly (Slip jumps to 0RPM), my TCM detects this and then unlocks the torque converter too quickly. This makes the slip RPM jump to a high value, starting the cycle all over again.

thought I'd share this moment. this is the first gearshift of my custom TCM for the 722.6 gearbox! it's harsh, but fixing shift firmness is easier than the control code to change gears!

please let me know in the comments, but I think for now I will turn the car headunit PC project into a shorts series (available on tiktok, Instagram and YT), and keep Ultimate-nag52 and other major projects as mains series on this channel.
obviously, once in a while I'll post a full length video on this project too!
