[WIP] The T3RD Volvo V50

The T3RD (nut TURD) is my 2007 Volvo V50 with a Tesla Model 3 drive unit. Current status is the drive unit is fitted in the front using a custom subframe. Driveshafts are mocked up using a 3d printed coupler. Early '25 I'll get these made in steel, weld and install properly. Then this vehicle will be used as the test bed for the new OpenInverter Model 3 drive unit pcb.

Great project. I can't wait to see it driving with this motor.
I had my driveshafts made here in the Netherlands, let me know if you need an address.

Even though this thread is not super active yet, I wanted to share some insights of the V50 ECM. So the idea was to create a replacement PCB that goes in the original housing. Therefore I bought some ECMs from East Europe to disassemble (one is a V70 ECM, that's for another project
).
Some research suggests that this type of ECM was also used in Ford trucks and it's glued together with silicone adhesive. The PCB is also glued down with thermal adhesive.
I would say that it does not really make sense to pursue the idea, because the the V50 only has a very limited amount of signals that are required in an EV conversion. Specifically, you'd have the CAN bus, power, PWM throttle and the AC pressure sensor. Perhaps some switching outputs such as the fan.
All in all, it's probably easier to just cut the connector and replace it with a dedicated module.
I just wrote this down for reference, so that my ECM purchase wasn't totally pointless
