Theoretical question about electric clutch pedal for TCC lockup
Hi,
I have a simple 2008 C200 W204 cdi. no egr, no maf, no DPF and very close to flashing my own ecu maps. (lack of courage for now)
I came from a Miata, and the lack of manual transmission is killing me.
So my thoughts are to use arduino for TCU. we all know it's possible. a little hard to do, but possible. (I only need manual shifting with the stock shifter, works on can-bus messages? hope not, but it's ok)
My plan was to let the arduino control the shifting according to all documentations. (if I need to write the code myself). and let an electronic clutch pedal control the TCC.
How?
We know the TCC works with PWM. I know that I can for example use POT with 0-5V on the clutch pedal, connected to the arduino.
The more you push the clutch pedal, the Less voltage goes to the arduino and the arduino code is designed to change the pwm of the tcc accordingly.
if I release the clutch pedal, the arduino see 5V and locks the TCC.
I can do this gradually with the clutch pedal and get a smooth locking, or fast locking, whatever I want, just like manual.
and if I will release the clutch pedal while sitting at a red light on idle, the engine should be stalled.
As for all error codes I will get from Engine controller, I thought about coding the car to Manual. I don't care if the ECU and TCU talk to each other or not...
It's all theoretical. What do you think?
Thanks,
Erez.

Thanks but there is no manual Mercedes in Israel. I am checking about converting it to manual in Jordan. (already converted two VWs from auto to manual.
Did all the electrical changes myself, including coding.
It's a theoretical question. I might start working on it - if the wind blows in the right direction.
but let's be honest, It's not something I must have, it's just a really cool project to do (for me...)

How long the TC will last? Not sure. I don't think they're designed to be used that way. You would have to check the max applied torque values and check what kind of impulse you'd generate if you dump the "clutch"... I mean, it could be something that works fine, but 1 or 2 errors and you need a new TC.
Either way, I look forward to this project if you decide to go ahead and do it. Quite a challenge.
