Re: 2nd LDU blown in a month - EDIT: False alarm. [SOLVED]
doesn't the battery voltage play a role in fweak? Boxter EV has 360V, I think you have considerably less.

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
There is no reason to run anything externally. The water comes from below, flows around the cover and exits at the top as before. Only the space for the gap could become tight, so it makes sense to drill a hole in the channel. The hole would then be where the word "seal" is in your picture.

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
Moodifying an existing manifold should be easy. The tube is difficult to press out, but shortening it up to the retaining ring should work. Then you only need a cover in place of the sealing ring that leaves enough space for the shaft and has a gap to the shortened tube. If the gap becomes too small...

In addition, I have also led the programming connections for the STM32 out, so that I can connect a ST Li...

Re: Accelerator pedal dead zone

For me, the behavior of an ICE engine is exemplary. Whether t...

Re: Tesla LDU Controller Stops Working with Aggressive Throttle
ocurlim is the peak current that is allowed to flow through the inverter and motor. If this is exceeded even for a fraction of a second the inverter will shut down. It is a safety feature like a fuse (but much faster than a fuse). I don't know what a good limit is for the LDU as I don't have one, h...

Re: Jumpy start, but smooth accel on SDU in VW T2
It's also worth noting that the throttle dead zone makes this "feel" worse, because your foot isn't used to finding the zero point. I don't use regen so my throttle doesn't have the 30% deadzone, and I found that made the experience quite a bit better. uhi22, tom91, I and others have disc...

Re: Inline wire HV disconnects that are IP67+
Shipping shouldn't be a problem. I can get the parts and send them to the US.
You should check whether the M25 cable glands are enough for you and take the lengths into account.

Re: Inline wire HV disconnects that are IP67+
If only the cables are to be extended, I could imagine a combination of a threaded sleeve, connector and two cable glands. Inside it could be isolated with shrink tubing and/or casting resin. The shield would also go through. Definitely the cheaper option.

Re: where to pass TUV in Germany
You should maybe change your request at the TÜV. There is the VdTÜV leaflet 764. It summarizes the important regulations for the conversion to an EV drive. When you report to the TÜV, you should state that you have this leaflet and have designed your conversion accordingly.

Here is the input circuit for the LDU. I think it's the same with you. You can, for example, pull the signal externally with a 10kOhm pull-up resistor at 10V to 5V and lower it with an arduino with a mosfet to ground and PWM as you wish.
