Hi all,

Some of you may know that i was working on a digital dash for the stock Nissan ecus.

Well the time has finally come! I have got all the parts together to make 10 and already have made one to prove the concept.

Attached is a pic (taken with my phone) that shows it in action, and sitting there with the (proper) Consult connector.

It plugs into the Consult diagnostic port and displays 8 sensors at a time, in realtime.

The sensors/data you can choose from are:

rpm

speed (km/h and mph)

afm voltage

injector pulse width

injector duty cycle

coolant temp

ignition timing

tps voltage

absolute tps position (%age)

EGT voltage (if supported by ecu)

o2 sensor voltage

AAC position (%age)

battery voltage

Lean/Rich Indicator

Flags (On/off indicators): Closed TPS, A/C Relay, A/C Compressor, Fuel pump, start switch, VTC solenoid, thermo fans, and a few others.

 

All of these variables depend on whether your ecu supports them.

The device also has a serial port so you can connect your laptop to it and log the data. I am currently testing a program that pulls fault codes and erases them, logs data, does a fuel map trace(!), and a few other things.

You can also read the stock maps from the ecu with a laptop. And no, you can’t tune the ecu with this!  

It also has a peak-hold function, so it will remember the max rpm, duty cycle, pulse width, afm voltage, water temp etc, and store it in memory for recall later...

Final price is $300AU + shipping. Those of you in Sydney are welcome to come past Unigroup Engineering and check it out (when i'm there, let me know before hand).

 

I can either sell a basic version which shows the variables that 99% of Nissan ecus support, or do a test on an ecu from your car so I can custom make one which reads out as many things as your ecu supports. A custom one might not work on other Nissans though.

Just wondering if there is a programe available for a pc that will allow you to hoock it up through a com port to monitor the same info if you dont want/need to mount it in your car and might be able to show all of the senser outputs at one time.

Currently a PC program is being developed that will monitor/log the same data that the display processes. This means that you can have the dash installed with a laptop logging everything the dash displays.

There are already programs that do monitoring/logging and many other things too.

So did you want a PC program that worked in conjunction with the display, or just a program that had similar features to it?

I plugged my mates (oosh's) one into my car but it only read one o2 and afm. I have a gtr engine in a 32gtst and his is a gtst rb20. Are they different between models?

Yes there are currently 3 models available. The generic n1 model (which works basically on all nissans except 200sx), the 200sx model (n1 model minus ignition timing, since 200sx ecu doesnt support it), and GT-R model, which is basically n1 plus 2nd afm and 2nd o2 sensor.

Im not sure how these units work and not an expert on computers either. Just wondering if there was a way to get a laptop to translate the signals that come back through the consult port its self without the use of the unit.

Im guessing not but just though I would ask and how.

Is there any way of linking other imput signals for such things as oil pressure senders or aditional temp sensors etc?

Forgot to ask a couple more things.

I read somewhere it will work with the piggyback style units as well, will this then show the true signals for what is actually happening in your motor or just what the original stock ecu is "seeing" after the piggyback unit has changed the values?

Also would this work with re-written ecu's that have had speed cuts taken off or written to suit bigger afm or injectors?

Sorry if any of these questions have been addressed already.

No you can't use a laptop on its own to use the translation. You need an interface between the ECU and laptop, which this display has built in.

The display has a provision on board to allow extra analog sensors to be plugged in. If your extra sensors spits out an analog voltage the display can be used to show these.

It will work fine with piggyback units, and will show what the ECU is "seeing".

Yes, it will work with chipped ECUs. I have mine working n an sr20 ecu with 600cc injectors and z32 afm.

Yeah you can get hold of your wiring diagram and test with a multimeter to make sure the 5 wires are still going where they should be.

Alternatively, you can find someone else in Melbourne with one who can help you..

Update: A logging program is now available, which actively logs the datastream from the NissDataScan.

This means that you can log the data AND use the display at the same time! The best thing about this is that the program is free! It's available for download

here

Note: This program will not work without the NissDataScan, and it useless on its own.

      R34 GTR Seats / No longer reclining

      By bilbo117 · Posted

      Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers

      Those above shitboxes, mediocre and above usually have a turbo strapped to them, hence the slightly higher octane is required.

      Blue slip

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
