Just too cute, ordered the Nissan VQ set 😍 Get 10% off yours with code: OOPSIDITITAGAIN

I think this is the first ad I've intentionally clicked on in all of history !? Such a cool idea and look to be executed really well !! Got the BMW's covered: https://disagree.de/en/collections/kopfdichtungen-fur-bmw-motoren And us weirdo's with Nissan's: https://disagree.de/en/collections/kopfdichtungen-fur-japanische-motoren/products/miniatur-einer-kopfdichtung-fur-nissan-vq-30-35-37

I suspect I'm not alone in being amazed at the depth you are going to here !! Respect 👍

Looking forward to seeing the progress 👍

Got a board assembled and tested ok, hopefully the switches stay put !! Yet to actually validate the buttons are functional for ECU map changes, will do that tonight. Then i have to try and capture the Nissan CAN (?) signals for cruise control light illumination. LED illumination looks good compared to the radio button side :)

New boards and the switches arrived, incredible performance from both outfits ... boards ordered from China on Saturday 4pm and were manufactured and delivered on Wednesday, amazing. These switches are TINY ... might need to get some solder paste and try to reflow them (heat in a pan or similar ) but will have a hoon with some hand soldering first.

Have ordered some ultra small tactile switches to use instead of trying to get the button pads to work. They are only 0.3mm thick and less than 4mm across. New PCB's on the way to work with the new switches 👍 Link to the switches: https://sten-eswitch-13110800-production.s3.amazonaws.com/system/asset/product_line/data_sheet/236/TL3312.pdf

Got the roof finished bar the weather strips finally, see the other thread for more detail. Also had the windows tinted to keep the heat down in summer ... hopefully this makes a big difference.

So I finally got a good finish on the roof, and learnt how to polish something properly finally it seems !! Never really had the hang of it before it seems. I'll likely leave it like it is and then get it re-cleared after summer perhaps so I can be sure there is a good thickness for UV protection. Only thing left to do is reinstall the weather strips now, these will be glued in with polyurethane. It's pretty hard to get a good picture of it in the garage ... will try and get something more fancy in the future.

Got the missing resistor and everything measures perfectly as designed !! Pretty happy with that. Unfortunately something I didn't count on is the little rubber pads in the membrane being shitty conductors and throwing out all of the measurements 😕 So I'm pretty confident that in the car it would not function well at all ... will try and clean the pads but can't see it improving things hugely. Will then look to silver paints or other things i can add to the little membrane pads to give a better connection.

Was just looking at some VQ37 engine info on the net and noticed the E46 got a mention in the swaps area, what a funny surprise 🤣 Definitely had to do a double take there ... https://www.drifted.com/vq37vhr/

A beauty at the Birkenhead New World... Though @Sammo might have had a make over!!

Hey and welcome my E46 brother ... can't be of any help with your issues sorry but thought I'd say hi

The balance of the components arrived today from RS and I got a board assembled as much as I could. One of the resistors was in the correct bag but the part was of the wrong value So held up until thats resolved, and of course it was the one weird value which came from the UK. Have to drill a missing hole in the board before I can at least test fit it and check the LED brightness etc.

Got the new tyres ahead of the wheels which are still looking like September. They sure look big when not on the car !! 235 and 255 PS5's.

PCB's arrived ... really impressed with the overall experience with JLCPCB !! Waiting on the remainder of the components from RS so i can assemble a board and test everything out. I'm expecting some minor fitment issues which may need a rev 2 but we shall see.

Forgot to add I found the very start of some rust in the left A pillar. Only piece of rust I've seen in the whole car !! Was essentially just a paint bubble and I assume an imperfection in the e-coat which allowed the start of it. Got onto it with a little wire wheel, rust converted it then added epoxy primer and some colour matched blue over the top. Glass back in !!! The tint looks awesome and will be sweet once it's done all over. Will get to finishing the roof sanding and polishing tonight Then tomorrow ... wash the dusty thing !!!

Got the roof lining back in while the rear glass is out, very easy to slide it in the big hole rather than taking the seats etc out Turns out the new B pillar covers I got (and have recovered) are slightly different to the ones that came out, they did work but were slightly shorter and the belt adjustment is a bit tight 😕 Might get the ones that came out re-covered at some point but can't be faffed for now. Have run cables for the dashcam I am installing along the way (Viofo A139 Pro) so it will be a high quality install with the permanent power wiring for parking mode etc. Also got the rear glass tinted (Xpel 35%) while it was out and will take the car in for the rest of the job once mobile again. Mostly this is because I have no A/C after the engine swap so will be great to keep the heat down a bit !!

We're almost there folks ... second cert inspection done and the glass is going back in today. Have re-sanded and polished the front and back where the new window moldings will go also. Hopefully tonight will complete the sanding polishing of the rest of the roof then can put the rest of it back together 👍

Took the E46 out for a spin yesterday with no front or rear screens, nothing like the wind in your hair 😆 Also got a set of Michelin PS 5's ahead of new wheels arriving in September, now I just get to look at them stacked in a neat pile and wait.

All good for sure, I just read it as helpful advise 👍 I'm just going to split the difference and use a set value for all then can adjust from there if things look weird ... just ordered everything I need from RS (including new LED's so can try to not reuse) and will get the boards ordered this week.

Ya I think so, using EasyEDA which I believe is owned by or otherwise tight with them and it's cheap cheap plus good turn around it would seem !! Not quite sure if I am ready to hit the go button just yet but for the price i think I should just to learn whats wrong and how they come out. Powered up the board today and all the LED's look to be the same brightness, to the eye at least. Have got another thread going with the electronic folks to see if there are some other ideas. https://www.electro-tech-online.com/threads/circuit-reverse-engineering-different-led-resistor-values.165113/ Looks good in a picture now at least which is encouraging 👍

Have started on designing the PCB for the cruise control side and its looking ok ... I think I'm in a good place for the actual controls, and have just got to add he little LEDs for the illumination now. Took some good photos of the existing board and have marked out the circuits that are used for the lights. Will just research why they have different resistor values for each LED ... I'm sure there is a good reason for it. Will add the LED's and resistors to the circuit tonight and then i can refine things a bit, 3D print the board to test fit and at some point actually order the PCB(s) !!

Damn you put a hex on me there Yep i setup the IR receiver on a breadboard and captured the signals off the remote but have yet to try and play back or otherwise deal with the captured data. Interestingly the captured hex for the items which are already working did not match so either I'm not getting it or there are multiple commands (generations ?) for the same thing. What I captured for the phone function I need to implement was: #################################### Basic Dump ######################################### Protocol=NEC Address=0x7286 Command=0x56 Raw-Data=0xA9567286 32 bits LSB first Send with: IrSender.sendNEC(0x7286, 0x56, <numberOfRepeats>); #################################### Full Dump ######################################### Protocol=NEC Address=0x7286 Command=0x56 Raw-Data=0xA9567286 32 bits LSB first Send with: IrSender.sendNEC(0x7286, 0x56, <numberOfRepeats>); Raw result in internal ticks (50 us) - with leading gap rawData[68]: -65535 +180,-87 +13,- 9 +13,-32 +13,-32 +12,- 9 +13,-10 +12,-10 +12,-11 +12,-32 +12,-10 +12,-33 +12,-10 +12,-10 +12,-33 +12,-32 +12,-32 +13,- 9 +13,-10 +12,-33 +12,-32 +12,-10 +12,-32 +13,- 9 +13,-32 +12,-10 +13,-32 +12,-10 +12,-10 +13,-32 +12,-10 +12,-32 +13,-10 +13,-31 +13 Sum: 1325 Raw result in microseconds - with leading gap rawData[68]: -3276750 +9000,-4350 + 650,- 450 + 650,-1600 + 650,-1600 + 600,- 450 + 650,- 500 + 600,- 500 + 600,- 550 + 600,-1600 + 600,- 500 + 600,-1650 + 600,- 500 + 600,- 500 + 600,-1650 + 600,-1600 + 600,-1600 + 650,- 450 + 650,- 500 + 600,-1650 + 600,-1600 + 600,- 500 + 600,-1600 + 650,- 450 + 650,-1600 + 600,- 500 + 650,-1600 + 600,- 500 + 600,- 500 + 650,-1600 + 600,- 500 + 600,-1600 + 650,- 500 + 650,-1550 + 650 Sum: 66250 Result as internal 8bit ticks (50 us) array - compensated with MARK_EXCESS_MICROS=20 uint8_t rawTicks[67] = {180,87, 13,9, 13,32, 13,32, 12,9, 13,10, 12,10, 12,11, 12,32, 12,10, 12,33, 12,10, 12,10, 12,33, 12,32, 12,32, 13,9, 13,10, 12,33, 12,32, 12,10, 12,32, 13,9, 13,32, 12,10, 13,32, 12,10, 12,10, 13,32, 12,10, 12,32, 13,10, 13,31, 13}; // Protocol=NEC Address=0x7286 Command=0x56 Raw-Data=0xA9567286 32 bits LSB first Result as microseconds array - compensated with MARK_EXCESS_MICROS=20 uint16_t rawData[67] = {8980,4370, 630,470, 630,1620, 630,1620, 580,470, 630,520, 580,520, 580,570, 580,1620, 580,520, 580,1670, 580,520, 580,520, 580,1670, 580,1620, 580,1620, 630,470, 630,520, 580,1670, 580,1620, 580,520, 580,1620, 630,470, 630,1620, 580,520, 630,1620, 580,520, 580,520, 630,1620, 580,520, 580,1620, 630,520, 630,1570, 630}; // Protocol=NEC Address=0x7286 Command=0x56 Raw-Data=0xA9567286 32 bits LSB first uint16_t address = 0x7286; uint16_t command = 0x56; uint32_t rawData = 0xA9567286; Pronto Hex as string char prontoData[] = "0000 006D 0022 0000 015B 00A7 001A 0011 001A 003D 001A 003D 0018 0011 001A 0012 0018 0012 0018 0014 0018 003D 0018 0012 0018 003F 0018 0012 0018 0012 0018 003F 0018 003D 0018 003D 001A 0011 001A 0012 0018 003F 0018 003D 0018 0012 0018 003D 001A 0011 001A 003D 0018 0012 001A 003D 0018 0012 0018 0012 001A 003D 0018 0012 0018 003D 001A 0012 001A 003B 001A 06C3 ";

It's real alright This is the display here: https://www.waveshare.com/product/raspberry-pi/displays/7.9inch-hdmi-lcd.htm You can see it in action here although looks average in video, it's very crisp and the colour is great ... will change the gauges to an amber theme soon to fit in better with the rest of the car. https://youtu.be/l5xILC-A0a4?t=32
