digital dash device for stock ecus

Hello everyone,

I have recently built a device for the stock nissan ecu. Attached is a (crappy) picture taken with my phone.

It plugs into the Consult diagnostic port and displays 8 sensors in realtime. This means that CA18 vehicles will not work with this as they dont have a consult port.

The sensors/data it can display are:

rpm

speed

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 for: Closed TPS, A/C Relay, A/C Compressor, Fuel pump, start switch, VTC solenoid, thermo fans, and a few others.

The device also has a serial port so you can connect your laptop to it and potentially log the data. You can also read the stock maps from the ecu with a laptop. And no, you cant 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...

I will soon make orders for more parts, but wanted to gauge interest (if any) so i can work out how many of each part i should order. Of course, the more parts i buy, the cheaper it gets.

Currently the device looks to cost around the $300 mark, that includes the proper consult connector, and laser cut front panel.

Anyone interested?

Sounds like a good idea - would they be cheaper to make if you can just get it to output to a serial/usb connection so we can use directly with laptops? may make it cheaper thats all

which model skyline ECU's does it work with?

I'm certainly not trying to rain on your parade because I reckon this thing looks tops... just like a Motec type dash.

Blitz now have a item like the Apex'i RSM which plugs straight into the ecu plug and does a similar thing.

I would if PowerFC users can use this? No?

Sorry power fcs wont work with this. It works with the standard nissan diagnostic port, which i bet isnt supported with the power fc.

The thing will cost less without the LCD and that but i built this because i for one cant afford to have a laptop in the car all the time.

It does have an rs232 port so you can easily plug one in and start logging, sucking out stock rom maps etc.

It sounds good..

But a lot of that information like people are saying is readily available in aftermarket ECU. Even the S-AFC will display REVS, AFM voltage, o^2, and TPS -- and readily had for $400 now plus of course the adjustment factor. Its not everything your device looks like being able to display though. Will be useful for tuners I'd imagine.

The pFC is a full replacement, so yes, it does monitor all that (and probably more). Well it has to, to drive the car! In fact it does away with the total diagnostic port altgoether which is just for the stock ECU.

don't want to kick anyone in the balls here, but i think this is a great idea for stock ecus,

and although SAFC is ok you can't really connect it up and data log. so although its only $400 it doesn't do a great deal (almost a bandaid solution). so i think what impakt has developed is fantastic cos i know my microtech although its only $1200, by the time it got fireware upgraded (to support engine) + dash, + Software, + cable and dongle it was well over $2K. not tuned.

just a question, do these work with say and SR20?? i know tonnes of tuners out there that would kill for something like this in their cars (know a guy who writes maps and makes daughter boards for SRs).

cheers

Update:

Sorry, AFAIK the ECU doesnt support knock display through Consult, so my device wont be able to display it.

There is a lead time of around 19 weeks on the connector so I would like to see if there is anyone out there interested (pref. in Sydney) in a version without the connector to start. People who buy without the connector can have the device for $250 and I will supply the connector later on, if production goes ahead.

Also, I would like these people who get the device without the connector to help test and give feedback on the software. So far I have had it running since Christmas and I believe I have ironed out most bugs. Sydney people are preferred so I can update the software if I need to.

The device should work on any car with a consult connector, so far I have had it going fine on an S13, and on my U13 bluebird attesa. Other cars are most welcome to be tested!

Anyone interested? A link to a picture of my prototype is at http://sr20.net/gallery/albums/Misc/abp.jpg top pic shows the peak hold values, bottom show current values. If you look closely at the afm voltage (af1) you can see the voltage was just about to change – look at the last digit.

If you would like more information or would like to help me test the device please email me at [email protected]

Hi All,

The device is ready to go! I have organised all the parts to make 10. I also have the proper Nissan Consult connectors.

Final price is $300, and if you are in Sydney i would like to test it on your car first to make sure the device can read out as much as your ecu can support.

I have tested it on a pulsar gti-r, bluebird attesa, and r33 skyline gts4. More details in the for sale section.

      High temp brake fluid?

      yeah I've never understood that either.... And to answer an earlier question, I write the date on open bottles and throw them if more than 12 months old (which they almost always are, because I don't need to bleed them unless I'm changing lines/calipers etc in between)

      Nah, the one that hit the boot was a big steel locker, around 6 foot height, 4 foot wide and 2 foot deep, empty it weighs about 15kg and had about that amount of stuff in it The photo didn't give a good representation of the actual damage, the large ding on the passenger side was about a inch deep, the one on the driver was about 1/2 inch deep, right on the curve, where the inner boot frame doesn't let you get behind it with a dolly Basically the same issue with getting behind the damage on the centre of the boot We could have filled it all with bog, but my OCD would be triggered every time I looked at it, knowing what hides beneath  As for the locker, I did get the shits with it and put it in the scap metal bin, but, I pulled it out and it is now sitting in the garage at home full of car servicing stuff, cleaning gear and random tools, it's going to pay for it's indiscretions

      Whilst I typically don't cheap out on things, if I can save some money, like $1000, on a clean straight panel, that gives me $1000 to spend on other stuff, basically free money really 🤔 🤣

      Is the toolbox that damaged the boot seal the same item that fell on the car during the storm a while back?

      Who are you to deny yourself? I’ve said this many times to myself and apart from getting what I really want, I go quiet for a while whilst working out what I just did to my savings and how will I afford what it cost, then, next payday…
