Still interested in a kit.

Alternatively just a PCB, along with a parts list , schematic, parts layout and how to make the connector etc.

Some of the above seems to have been covered, I know, but the PCB is what is my main concern. I don't want to use experimenters or vero etc if I can help it.

got an assignment due next friday (or the following, forget). after that ill try make a shot at a pcb then find out about getting it manufactured etc. havent ever made a custom pcb so itll be something new for me (and i dont wanna keep putting it off)

I am also interested please.

NewKleer: I read that the port only appears/works on 1991+ model ECUs. Would an 89 R32 with a later model ECU work you think? Or are there sensors that are not present in the older models?

im pretty sure if it has the consult port then it will work. very early 89 models didnt, but i believe someone said they did come with them by late 89. to be safe i say 91+ most places i talk about them as ca18's dont have consult, and ca18's stopped in 91. all other nissans i know of 91+ should have it (at least the common ones, pulsar/skyline/silvia/nx/etc)

the consult protocol is designed so that most ecu's only gave a subset of all available sensors, so it shouldnt matter if it doesnt support a sensor here and there (eg ignition timing isnt supported in some s14's or something), as all the other sensors will work

I'll be making an interface module from just prototype board (Have already got the component layout for the board) in the coming week and intend doing a tech writeup on it - probably end up posted on my webpage. Watch this space... It will be as close to a kit as you can get with you having to buy all the parts yourself.

I just can't get hold of the consult connectors that's all so will likely make up one from ATX power plug (as posted previously in this thread).

Thanks for your reply. When I get the car back I'll check for the port. Cheers

just an update. i got some time over the weekend to start work on thecustom pcb, and ive got a draft one complete. main problem is that i need to make sure the layout is 100% right as theres no room for error since its only economical to make large manufacture runs as theres like a 70-100$ overhead

the other issue i thought about was whether it would be useful to have the serial connector on the pcb, and u plug the actual device right into the laptop (its not that big). only problem is it would need some kind of custom enclosure which has a serial port slot on the end. ive no experience with custom plastic boxes or anything so at this point the pcb design is similar to the current ones ive made, but will have removable cables (i might make the cables myself as they would be the trickiest part, but still undecided on that)

when i get home tonight i can post a screenshot of the pcb design that has the serial connector on board, if anyone knows where to find/make a custom enclosure for it, then youll have an idea of the size im after (only a touch wider than the serial port connector)

heres an example (interface2.jpg) of what the interface could look like if i can find (or find somewhere that can make) an enclosure thats could fit around this. then there's only one cable coming off it, and it plugs straight into serial port (wouldnt be much bigger than a serial plug)

interface1.jpg is the current one im working on, assuming i cant find any better box to put it in.

edit: interface3 is a test for possibly putting it in a parallel port connector shell (but with serial plug)

normal sized - i decided that smd is going to be too difficult for most people to solder. normal sized shouldnt prove too hard.

as long as it has a consult port it should work. dumping rom can be temperamental, but if u have problems then calumsult can resume dumps

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
