  • Successfully told a BeagleBone to do CAN
  • Ordered parts for motor and transmission mating
  • Taking delivery of the shaft coupler maybe tomorrow
What are doing for a leaf coupler ?

Yes the Dashboard receve the oil pressure information as on the old vw.
I think if there is no information you may have an alarm over 1000 rpm.

Yes, found it today :)
The alarm indeed starts only above some rpm. But there is also a reverse alarm: if you pull the signal to ground (=oil pressure ok) at 0 rpm you get a STOP! message also. So I either have to live with this or pull the signal to ground selectively with my custom "ECU"

Finally I can answer that, bottom to top
  • Custom fitting that adapts the VW spline that I cut out out of the clutch to the KTR coupler
  • KTR Rotex 38 GS
  • Adapter ring that adapts the KTR coupler to the next piece
  • Nissan Leaf spline from New Electric

I too would like to get more details on the source of the Leaf spline part.

Also would it be possible to get another picture of every component separated? This is by far the cleanest example of a Leaf motor adapter I've seen (Excluding Damien's of course). Bravo.

Sure, let me google that for you ;) http://www.newelectric.nl/
Just inquire for a Leaf spline adapter.
I think they are here on the forum as well.

Yes, but also ten times the price :o

I'm co-owner of New Electric Ireland and can answer questions relating to the group which has now grown to five companies :shock:

In Ireland we focus on vehicle RND and support numerous Open Source projects. I won't necessarily have at my finger tips answers relating to products or conversions from elsewhere in the group but I can get answers with a short delay :)

Hi Kevin, The question I have for you is what is the cost of the Nissan Leaf spline adapter?

So this weekend was great. I had both Arber and his family and my father over to help me get back on track with the Touran conversion.

We test-mounted one battery brick (1/2 Leaf pack) under the car with no greater problems. The other half is residing in the boot right now. My dad could not stop working until we had this done at 23:00 :D

The adapter plates between motor and transmission are pretty much sorted. I use two 300x80x40x4 profiles to cover most of the distance. They are connected by U-profiles mainly for water proofing. Then comes the actual transmission plates which we made with the jigsaw :) It is only 15mm and we found out the hard way that it better be 25mm - the shaft coupler is about 5-8mm too long. So I went to a random steel working company today and found a 100x460x8 aluminum plate in the scrap. Will saw it in half and thereby add the extra distance.

Mechanically I just need to make a motor mount and the drive drain is in, yay :D

EDIT: maybe I should mention that Arber came from Slovenia which is 900km away - so: thank you very much :)

Nicely done!

I guess that means you can just put cells in the back for now. To simplify the build.
I just cant wait for results.

Vacuum pump is in :) Used the original rubber mounts

And transmission is in.
Now need to make a motor mount, connect up the drive shafts, make some temporary DC cables and off we go :D

You can cut that mount near the hole and make a hole higher up. As long as mount is flat under. Then buy one 6mm flat piece of steel cca 100mm x [whatever vertical] and get it bent under bottom. Fit one end in the mount and another down at the motor mount in such a way it will carry motor even if a bolt falls off.
Side mounts are only to stasbilize motor. Real bi*$#h it to fit the rear mount in. Does your rear mount come with transmission?

Well I believe I've sorta done just that, see below :) He who can't weld uses profiles and screws ;)
Yes the rear mount is attached to the transmission, easy peasy.

I've installed the Leaf wire harness and connected it up to switched 12V and GND. Only CAN missing. I might tap into it at the power steering. Inverter is powered, I can connect to the wifi.
Also installed a coolant pump from Mercedes, it starts to run with the key switch. Haven't decided on what radiator to use yet.
Also rigged up the vacuum pump to be controlled by the new "ECU", works beautifully.

More annoyingly the car has developed and airbag fault. I wonder if my messing around caused it :?:

Tomorrow I should be ready to spin some wheels.

Very nice! I like that mount.
Did you disconnect some GND wire or cut any harness? Inside harness there are usually some wires that serve just to connect all the connector GND references. If you cut one you may disable a lot of things inadvertently.

Or maybe car is sensing a voltage reference change. Did you connect 12V battery?

We have liftoff :D
Connected my trusty 32V Sinopoly pack.
Drove some 5m up and down the driveway. There is not a lot of torque but still enough to pull against the handbrake in 3rd gear.
I took quite a liking of CAN today. I "wired up" the various control signals like key switch, throttle, brake via just mapping them on the CAN bus. So much easier then finding all that stuff in some convoluted wire harness. So there are just 4 wires connecting the Nissan to the VW world.

I've likely found the source of the airbag error. I had connected some "front bumper sensor" (whatever it senses) to the reverse switch of the transmission. They have the same plug. Stupid.
But I think the error must be deleted for the light to go out. Can that be done with Savvycan? Whats the cheapest way otherwise?

A vagcom cable should do it. About 10 Euros on ebay. Congratulations on the test drive. I have an 80v pack ready to drop into the E46.

Yep, ordered one.

Here is a video from the Touran series:

Looking great!
Glad to see some relatively modern VAG related conversion going on here. Have a 2003 A6 C5 1.9 Avant that has the makings of a donor. Good to hear how you have found a liking for the CAN on these as this was one of my thoughts on how difficult it was to get around acquiring all the relevant messages you need to keep the dash from lighting up like a Christmas tree :D .
Plan to go the Leaf power train route also. This thread is my new sticky ;)
