Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance
A small update regarding my SKF seal and speedi sleeve. I pulled the encoder whilst fault finding this issue. The wheel was still dry. A little residue on the encoder but that might have been from the silicon used to seat the seal. Edit: forgot to mention that I think that's 17k miles on this set-up...

Re: LDU Forward and Reverse LV power issue
What DC-DC are you using? This one. https://shop.fellten.com/shop/tdc-iy-320-12-dc-dc-converter-206-454vdc-1kw-13064?v=79cba1185463 Think I found the issue; my little Davis Craig water pump was dying and pulling like 50 amps (I won’t mention that I fitted 40amp fuse to it temporarily 4 years ago) -...

Re: LDU Forward and Reverse LV power issue
Yes, there’s a load somewhere that’s significantly pulling the DCDC power down, or its enable signal is being intermittently interrupted (probably the latter). What I don’t understand is why it only happens when selecting a direction. Will start testing current draw as a first step. I also have a ch...

Re: LDU Forward and Reverse LV power issue
Just to add, I have a 5 amp fuse on the 12v FWD signal which doesn’t blow. How can such a drain be evident without blowing the fuse?
I recall Johannes saying that once the gate drive boards are active they can be quite power hungry, but this fault / issue is new.

LDU Forward and Reverse LV power issue
When selecting a direction, either FWD or REV, the LV current draw seems to be very high. Only occurs when pulling a direction high. I wondered if I had a short to ground on the car but I’ve eliminated that by giving the FWD pin 12v directly from the battery and the issue still remains. I can have a...

Need to test that sensor today. Thanks for all the help.

How could I test the position sensor? I guess I can measure from the sensor end, that it’s getting ground and power. Not sure how to test the encoder channels wires. I guess web interface does not show the readings from encoder, or does it? Test continuity from the wiring encoder pins to the 23 pin...

Boost very low, fweak very low, fweakstart low, throtramp very high, ampmin high.
Regen setting also very aggressive.
UDCmax @ 350!
These are my settings running LDU base, 360v nominal battery (400v). Firmware v5.20r.

Please can you post your parameters and firmware version. It makes no sense that you're munching through drive units like this.
Have you double checked that the OI logic board connections are perfectly clean after getting wet with coolant?

Re: Tesla LDU Controller Stops Working with Aggressive Throttle
I’ve always left the value of my Base unit at -2500.
However, when bench testing I used a value of -300 and gradually increased it until I was comfortable that there were no underlying issues.

Re: finished or functional ev ?
I will probably change battery in Mazda MX3 i have from 2012 and it has 150000km electric and some 250000km ice logged. When i start i will pin it here as a new project since i finally decided to put outlander motor in it and lose the transmission... :twisted: This sort of mileage is impressive 👏🏻

Re: finished or functional ev ?
I’ve been daily driving mine for just over three years and completed nearly 25,000 electrical miles. I consider it finished from a project perspective, but there will always something to do to it. I’d really love a bigger battery and CCS at some stage.

Do you have the correct coolant? Incorrect coolant or mixture will certainly corrode steel components.

Re: LDU Tune Issue - WOT Mystery
Strange issue. The main differences from my tune is that I run a lower throtramp and ampmin setting.
I am however running one Chevy Volt pack and it's becoming a little saggy in its old age.
