When it goes to neutral, it doesn't have enough oil, the same thing happened to me after an oil change, when it was reaching the 5th gear it would go to neutral!
I read somewhere that my ML270cdi has an incline sensor inside the 722.6 already. There is an option to enable/disable it in MB Star diag. It certainly automatically holds onto a low gear when going down a steep hill when you go onto overrun. Also is there a timescale for the end of beta testing, or do you want another beta tester? I have 2 Mercedes vehicles, a 2002 ML270 and also a 2003 LWB MB Sprinter with 722.6. I am a professional embedded C programmer in the automotive field already, and your work so far is fantastic.
Awesome that you are doing this. I just signed up, would love to contribute a little code if you accept contributions as well, specifically I would like to add a debounce to the shifter as when I slap the shifter left to downshift sometimes the spring loaded lever bounces back and immediately shifts up.
Are there any options planned to have this run in a car in essentially a stand-alone mode ? In Other words a custom EMU or even a non oem Mercedes application.
I'd also like to know. Not a lot of options out there for moderately modern and accessible auto transmissions which can handle a lot of torque in a project car.
@@lachywocky I've been following this project for some time now so I can answer this based on information provided in previous videos: for standalone applications it is assumed that people will be using Ole's EGS51 based controller. Ole's controller can take sensor information directly so it doesn't rely on information arriving on a canbus - this is essentially what most people will be implement if installing into a engine/trans swapped car. There is absolutely no reason why you couldn't run this controller in a car that wasn't built for it and that is what I will be doing. I am intent on pairing an OM606 (factory EGS51) with this controller in an old G wagon I have. This would not be possible (easily) with an immobiliser deleted stock ECU mind, since that would expect messages in EGS51 protocol. If you find the 722.6 pdf online it may be of some use in seeing some of the difference between EGS51 and EGS52, it's a bit of a jump. I will be using a standalone ECU configured to accepted messages in EGS52 protocol, which I am testing currently in my W210. The configuration in this code (available on github) is modifiable to include any tyre size and rear diff ratio you may have in your standalone car. Equally if you wanted to use this alongside a standalone ECU in a petrol sense (Haltech, Megasquirt, Speeduino, RusEFI) then you would need an interface in the form of an arduino which would sit between a gearbox canbus (Interface, Ash's controller, shifter) and a powertrain bus. When the TCM sends messages for torque request for gear shifts in Mercedes' proprietary message protocol this interface will play equivalency messages to the standalone ECU. Messages would have to go the other way too for throttle position sensor (maybe) if petrol but definitely pedal position sensor as well as manifold pressure etc. It is a bit of extra work over Ole's controller but in terms of maturity of the hardware and software I'd say worth it.
Yes my engine ECU shows the amount of static torque being produced, not load. But, I'd still need to internally work out how much torque the engine usually produces to accelerate the car 'y' amount, and then see if the current values are more or less, indicating either up or down hill.
Hahaha did you have your phone attached to your head for filming this? 😂 Love it, awesome work mate!
it's fun to see you driving Zittau city I know that roads! :)
I just finished watching all your videos on the tcm. Im very impressed you are a true tuner in every sense of the word.
This is awesome. I can only imagine what your skills will do for the 8hp zf transmission. Great job bro

It's a shot in the dark, but maybe you can use values from the ESP yaw rate sensor(s) to let the gearbox know if you're going up or down a hill?
Yaw sensors are internal to esp and are not broadcast over can, so my TCM cannot access them
Could you fix the gear searching by taking into consideration fluid temp?

@@bentait2462 seems nicely developed, so heres hoping.

Output shaft rpm relative to pedal input?
Dont know if its the same for all ECU's, but usually the ECU has some sort of engine load. So maybe this can be used for the hills?
