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?

T.

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.

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 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 attesaman@hotmail.com

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.

    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
