I have been running firmware version 5.14.R for nearly a year. This version had a couple issues in my application. I would get an occasional current spike (causing an overcurrent event) when gently coming off throttle to regen (OC never happened when the motor was under full load). To make the car u...

No testing yet as it is -2deg C outside and i took Mazda battery in house to power my solar. At least it is warm. Wow. That's what you call a hybrid battery! :D I will try 5.20.R tomorrow. If anyone else has experience with this sine version I'd love to hear your feedback. Edit: now updated and wri...

Hi Arber

Did you report back on this (sine version)? Would appreciate your feedback.

This will be a quick write-up and update, but Howard kindly sent me a PTFE lined rubber seal (over steel frame). It's made by a company called Peach Motor Parts in the US. I understand its application is for Snowmobiles but it almost has the required dimensions of the Tesla OE seal, albeit with a la...

Impressive how quickly you are bringing this build together. Inspiring stuff.

I'd love to join too. Might need a bigger battery or tow truck to get to Somerset.

Had a two hour wait for a CCS charger at Cobham services last Sunday (in family car), so it seems fast charging is no longer thus.

Received a PM regarding code for the gauges. Here it is and I hope it helps others: #include <FlexCAN.h> #include "canmessage.h" CAN_message_t outMsg; CAN_message_t inMsg; #define LSB 0 #define MSB 1 #define UNSIGNED 0 #define SIGNED 1 //Vital statistics int16_t InverterTemp = 0; int16_t M...

Well if the car is first in it's kind / class then the engine mcy might reveal allot of canbus signals. So I'm not too sure about not needing it. It's needed for reverse engineering purposes and not for functional purposes. I can only speak about this car (a Dec 2000 986). Post conversion, all func...

Thanks for posting this information, Howard. The community must find a solution otherwise there will be a lot of LDU off the road in the near future. I cant find a local link to the snowmobile PTFE lined water seal in the UK. Do you have further information on European suppliers? It only takes me an...

Data point and update: after 3500 miles my SKF seal is leaking and progressively getting worse (I have a drain plug so it's dumping coolant overboard). I can see the expansion tank level dropping every few hundred miles and am having to keep it topped up. I'm not going to have time to remove and exa...

Not sure if I understand your question.

You do not need the original ECU for the conversion. This is no longer required:

Trying to make sense of what's happening here. When motor going forward it shows reverse on parameters page on laptop. When in reverse it shows forward. Even trying to use the button swapped setting on perimeters page it shows the same thing. Should I just ignore it or is there a reason or a fix? I...

Answering questions from PM received. Hello, Read your post/journey on converting your Boxster and really appreciate the info you posted. I have a few questions as I'm considering doing something similar: 1. Did you integrate/connect to the vehicle's canbus initially when you were first driving the ...

hello can someone possibly share the gbrl file to print a single open source ldu pcb board. I have a tesla ldu out of a SE toyota rav4ev. do i even need one for this drive unit? thinking tesla possibly has less proprietary structures in these units since tesla supplies the LDU to toyota.? prying i ...

A relatively small update for those interested: I’ve been continuing to experiment with servicing and preventative maintenance of The Large Drive Unit and in fact have had some excellent exchanges on the forum in the LDU rebuild thread located here. . Although, the thread has since grown arms and le...

What’s your voltage? UDCLIM being hit?

Hello. Thanks to everyone on this forum for the great information and explanations being shared. canadasconvert, I am curious if the firmware update solved your above issue or you needed to make any other parameter changes to solve it? I am having a similar problem that has popped up with the DERAT...

Sounds like a lot of drama for one trip - keeps it interesting!

Time for some preventative maintenance on all wheel bearings?

My setup at the moment https://photos.app.goo.gl/bLk8ut9ZBYKDt7DX8 https://photos.app.goo.gl/2szAt6ZSzLzh7wWa9 Lets hope I don't destroy the inner ceramic bearings and/or have the bearing stay behind. That’s basically it. It’ll just require a shock / jolt to release the spline. The outer wood block...

Can't Get Rotor out

In post two of this thread I describe how I removed the rotor. Method is Heath Robinson but works.

I don’t want to pollute this thread but can I ask whether the issues discussed also affect the sine version and specifically 5.14? Getting occasional overcurrent event during very moderate driving when on/off throttle. Seems to be no correlation to rpm. Only occurs during gentle driving. No OC when ...

Follow this in black and white terms and no conversion gets passed.

You can replace the output seals with the drive unit in situ but you do need to undo the drive shafts and pop the stubs. There’s a BMW / Febi Bilstein part number for the seals.

Just watched your videos. The car looks and sounds great.

Given it’s age, I think you’ll be fine with the DVLA.
