1991 300CE Mercedes conversion with Tesla LDU

new update on Tesla direction relays for SDU and LDU

Just received my tesla motor August 10 2021 still in crate had to go with the SDU instead of the LDU.
Ordered SDU logic board from JLCPCB to start installing.
Got into some problems in taking it up to the 3rd floor but will try again.

Finally got the tesla OME logic board off the sensors. Now waiting for PCB from JLCPCB

Car to be electrified.

High voltage box almost done

Interesting project will certainly follow this

Need to take motor up to 3rd floor another project
Removed inverter now having trouble removing logic board from current sensors.

New update completed drop in logic board.
Waiting on the STM32F103RBT6 processor.

20 pin sensor connection completed.

I do like your project. Keep it up.

Thanks

Very cool C124! Looking forward to seeing more updates.

Nice project. Do you have some pictures about the mechanical integration of the SDU to the rear axle of the Mercedes?
Seems to be a tight fit as you mentioned you had to relocate the inverter housing.
