FS: Digital dash and rs232 for stock ecus


Recommended Posts

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.

Update: A program is available which actively logs the data while the display is in use! A link is available on the NissDataScan page.

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 (which is around $15 around Australia). 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.

Here is a site with more information http://members.optusnet.com.au/impakt01/nds/ ] here[/url]

Some commonly asked questions are:

Will it work with an aftermarket ECU?

Nope, only with stock ECUs, also ECUs with are chipped/daughterboard installed.

Will it work with Power FC?

Nope.

Will it work with an interceptor like the Unichip or S-AFC?

Yep, but the display will report what the ECU "sees".

My car isn't in the supported cars list. Will it work with my ?

Chances are if it has the Consult port available, it will.

Penfold: My device works with GT-R ecus. I had it working with an r32 ecu today. PM me if you want me to send you one.

Squizz: My gauges aren't purple, they look like that because of the (phone) camera i used, they are still the stock blue colour. BTW this is a read only device, so it doesn't remove the speed cut.

Here are some more images i took the other day:

impakt,

This is an amazing achievement! I have had an ongoing bug with my GTR for some time and was only until yesterday that i found out that the oxygen sensors were shot by using an expensive $12,000 analyser.

Youre little device would have shown me the same zero reading for sensor 1 and radical readings on sensor 2, straight away.

I would be very interested in purchasing one of these devices although i have just forked out for a power fc and hand controller, so i will have all of the information on the hand controller and with map trace function. With the option of using 'FC logit' software from NZ, i cant really see the point in using your system as i can plug my laptop in the pfc and log using this program.

If i did stick to the stock ECU, i would definitely buy one and i will be sure to tell as many people as i can about these!

A few critical comments:

1. Use red knobs on the device or touch panel ones

2. Talk to a carbon fibre specialist to change construction material from metal (i can give you details of a moulder/fabricator of carbon and its alot cheaper than you think)

3. Make the device match the size of most japanese style electrical goods to give a more preofessional touch and to make it easier to fit into the car with other already installed goods.

I have a friend with a rb20 powered silvia, his car is having cold start problems and stall on overun problems. I am quite sure that your device could sort out his problems and would look extra cool to boot!

Keep up the good work!

I agree with BNR32.... excellent device and im sure im jumping the gun, but asthetically, it needs some minor work... in saying that tho, id happily put one in my car right now, as i dont give a fck what it looks like, as long as it tells me what my car is/isnt doing.... tho if u had a pretty one, id be all over it - like a fat kid on a smarty !!!

i have also PM'd u.

Kos!: Blue LCD screens are hard to come by. The ones i have seen cost over 5x the price of the green one.

I can see why you guys would like it to look better, but without spending another $200 on top, you cant get it much better than that. I do make these in my spare time you know!

BNR32: Its made of plastic, and the front panel is perspex, it's not made of metal :D

Penfold: You should receive your display today or tomorrow the latest.

There is free software available online that can read and clear fault codes, log data, suck out stock maps etc. I have all the free software here. Also, the more people get these, the more people will go out and write even more software.

Some ppl have been asking the same questions, so i'll answer them all here (again).

I cant make it look better without adding to the cost and complexity of making it (which in turns makes it cost more again).

I cant change the screen to blue, without (again) adding at least $100 to the cost. Most suppliers have the green ones in stock because they are the standard colour. Blue ones would have to be specially ordered, which means lead times of weeks if not months, and i would also need to order around 100-10,000 without getting completely ripped off.

If anyone knows of an electronics supplier that has blue lcd screens i would be more than happy to chase them up about it.

Attached with this post is a copy of the manual, which explains what it can display, and how the 3 buttons are used.

ahh, thats great, thanks

also, do you have them on the shelf ready to go ???

from looking at it all, i can only see one thing missing ....

a boost gauge ...

this would finish it off perfectly ....

even if it was a seperate module that had to plug into it is the ecu does not measure boost, being able to display all this stuff on one box is great !

cheers

I'd just like to add.. having a look over what this thing can read and display..

An absolute bargain! If you have any desire to work or diagnose any problems on your car and have a basic idea of how your car works, i think it would be invaluable, and easily pay for itself in workshop costs fairly quickly.

Seems to do what a lot of what the official Nissan consult device does which is *only* available to registered workshops and costing many thousands of dollars.
