Dala's Leaf buildthread (2015 Nissan Leaf)
My initial attempts at persuading the inverter to output more power was a failure. Check this screenshot

In this screenshot I added 10Nm to the demand. So it seems like the inverter firmware clamps to some hardcoded value to keep 80kW, which is a damn shame. I might try some other tricks, but it feels like either firmware needs to change (incredibly difficult) or an inverter swap from a newer Leaf (never done afaik)?

Time for some spring-cleaning!

I decided to install the summer wheels and do a proper spring cleaning session. The paint has suffered the salty roads for quite some time now, so time to give it some love.

Started with assessing the wheel-wells, they are surprisingly clean. Looks like my periodical winter spraydowns have helped with keeping the rust at bay. Here's the rear

But on the front the cast iron knuckles have rusted significantly. I gave everything a good degreaser and pressure wash before putting on the summer wheel setup.

I then focused on the paint. I did a pressure wash, degreaser, pressure wash, claybar+cleaner, P2000 compound, anti swirl compound and finally hand-waxed the paint. I think I spent well over 8h with the car, here's a picture midway thru

And then the final result, shame the sun went away, but the paint really shines Smile

There is still some OEM orange peel in the paint, but I'm unsure how much can be sanded safely...

Not much has happened, still waiting on some parts for a long needed project, but I wont post about it until I have all the parts I need Wink

Now for something completely different. The rear wiper was pathetic, so I inspected it. Turns out it was just about to crumble into pieces, so I replaced it with a newer Bosch unit.

I also have most of the components needed to start building some CAN bridges, still waiting for the final ones. I will send this all to a local electronics expert so they can piece it together. And yeah, it probably would have been faster to order everything from China, but I like to support the local businesses in these times Smile

A guy of the spanish EV build forum asked for an alternative provider of muxsan's boards because tindie was out of stock. Do you mind to sell some of MIDM boards you did for error?
What's you dev platform? I build muxsan code via avrdude in linux env but patching his makefiles manually.
Since COIVID-19 I hadn't time to go back to this, but the idea is trying to find a way to be aligned to muxsan avr studio build project but able to build on different platforms... and trying to do a choerent pull requests to muxsan repo.

p.s. thanks for this super interesting thread, is one of the thread that convinced me to buy a leaf (now a 2016/30wkh)... slowly planning upgrades after end of warranty when I'll have also more time to do it myself.

Yeah I could probably start selling some, since I will build quite a few Big Grin Shoot me an email via the website contact form and I'll get back to you asap.

For dev environment, I use Atmel Studio 7.0, but I'm on a Windows 10 machine.

Glad to hear you got a Leaf Big Grin These cars have so much potential, the mods are really gonna take off now when more and more are starting to play around with CAN-bridges.

I finished up the trailer wiring. It was the least fun I've had with the Leaf Big Grin

So to properly wire in the 7-pin trailer harness, I ran the cable into the boot and started to look for the light signals needed.
These can be taken from the left side.
- Turn signal left
- Daylight running light
- Brake light
- Chassis GND

From the right hand side light, the "Turn signal right". So this all means removing a ton of plastic panels to getting the wiring properly routed. Not fun!

But the payoff now is huge. I now have functioning trailer wiring!

NOTE! This car officially has 0kg of towing capacity in the registry. It is illegal to go on a road and tow. This picture was taken on the side of the road, I never recommend anyone to do anything illegal. Check your local legislation for how to go about for retrofitting a tow bar.

Ok I promise this is the last post regarding towing, and we'll get back to something more interesting Smile

So lets say I "Simulated" a proper tow run with a bigger trailer. It was possible to tow for 270km with a charge stop in the middle, going max 85km/h. Any faster than that, the air resistance from the big trailer cover would break the efficiency, as you can see from the picture it is quite a big one. It should be possible to go 160-180km on a single charge with the big trailer, which I am extremely satisfied with.

Now there is no reason to borrow an ICE anymore! Smile

I'm still waiting for some parts, but I decided to post this already since it is functional.

Okay so here is a big upgrade for the Leaf. The stereo. I have the base model of the Leaf, which has a pathetic attempt at a stereo. There is a tiny display on the unit that is used for the reverse camera, making it a pain in the butt to reverse with. It doesn't even do bluetooth music streaming. It screams basic. Take a look:

Oh yeah 2004 called and want their stereo back.

So what can we do about it? Lots. The base model stereo doesn't integrate with the climate control system like on the higher spec models. So on those it's not possible to change the stereo, since you then loose so much functionality. On this base model, there is a 2DIN slot that you can put whatever you want into. After doing some research, I found something that ticked all my requirements. These are

-Android based
-Will run Leafspy Pro
-Spotify
-Reverse camera compatible
-Front facing camera always recording
-Android auto optional

Turns out there aren't that many options that do this, but thankfully the 'Atoto A6 Pro' ticked all the boxes and more. I went with the A6Y2721PRB-G model, which also has gesture sensors.

Let's get to installing it! But not so fast, first you need to order these adapters:
-Axxess Aswc-1 Universal Steering Wheel Control Interface
-70-7552 WIRING HARNESS AFTERMARKET STEREO FOR NISSAN (07-UP) + SUBARU (08-UP)
-American International NDK780 2012-16 for Nissan Select Model Install Kit
-Steering Wheel Control and BackUp Camera Retention Harness AXXESS AX-NIS32SWC-6V
-Radio Antenna Adapter for Nissan/ Infiniti Scosche ref Part NAA2B Metra 40-NI12

After most of these adapters arrived, I started to install the stereo. To remove the middle console cover, grab the lower portion and pull it. The whole thing just pops out.

After removing it, it's adapter fastening time. I won't show every tiny detail, but there is quite some cables to adapt. I also tucked in the GPS & Wifi antenna that came with the stereo behind everything.

One thing that the Atoto unit comes with are extra USB ports. This is really useful, since the Leaf originally shipped with one USB port that was designated for ipods. This port only supplied like 125mA, which is not enough to charge a phone. The new ports are 1xQC @ 2000mA and 1x regular USB @ 500mA. This is a really nice upgrade!

This is what it looks like all mounted, maybe 3d-print a cover for them later?

After getting all the adapters in (minus steering wheel and reverse camera, still waiting for those to drop in the mail), I fired up the unit. After doing the Android setup, you're free to explore the unit and further set up all the apps you want to use. Note that I'm still waiting on the screen bezel, there are gaps on both sides of the unit.

I have a feeling the Leafspy app will be quite heavily used Smile

I'm particularly fond of Spotify right now. Worth mentioning that this unit has way better drivers for the speakers, I originally planned to change the speakers in the doors, but after listening to it with this new unit, there really is no need at all.

The screen is IPS and really hard to photo properly. But it looks amazing. This is what it looks like in full daylight, really easy to read the screen.

10/10 would install again. Now to just wait for the steering wheel/camera adapters. Smile
