In the last 15 years, I've seen how the OEM'S have been programming more and more with sensing. I remember when one manufacturer was developing a feedback type sense when a spark plug fired, to enable a signal to indicate what was in the PCM's program for comparison especially at high RPM's. I don't know what happened to that and since I retired in 2016, I haven't seen anything more about it. THIS sensing tool is definitely different than what we are used to. I hope this works out to be a big help. Thanks Mario for the info.
thats cool, great minds think alike cause i built myself one too about 4 years ago except i was using it for other uses. goes to show u that the only thing that limits ur scope is ur imagination. awesome video brotha.
I always thought that a pressure signal from high pressure gdi rail sensor is only good to be scoped if the sensor update speed is useable for scope use. Noise aside. So if a gdi high press sensor update speed is not fast enough, how can DDDi help ? We cant create a missing data...correct ? Example low cost in cylinder pressure sensor with slow update speed vs pico wps500, the pico is fast enough as such its signal into the scope is useable. Remember the old fluke pv350 older version was actually faster than its new one ? , as such people will use older fluke pv350 in lieu of wps500, but not with new version. I would love to see a true pressure sensor specialist take a deeper look at DDDi and see how much of a gdi pressure signal is true signal and how much is software "tuned".
The core functionality of the "tuning" process isn't using software at all, it's using hardware Op Amp filter circuits, so it's literally outputting a signal that has a "notch" type hardware filter. It's then amplifying the remaining signal that is within the frequency band that correlates to roughly 1/2 engine speed (fuel system frequency) this removes all of the noise and highlights the desired fuel system frequencies. Only the SENT decoder and frequency mode use software to process the signals. I'm actually putting the tool in the hands of several industry experts to evaluate it, Scott Shotten has one for example, I'm sure you will see more peer review in the future. One weakness the tool has, is that it can, as you pointed out only report what is actually there. This becomes an issue when rail recharge events directly overlap injector events, making a known good helpful in diagnosis.
@@automotivediag8502 yes bmw has similar set up as well that is kinda confusing if you’re not use to interpreting their data; however Mercedes ME misinterprets it’s own cylinder bank layout and never provides accurate misfire information
❤❤❤❤ thank you very much for the video. I have a small request. If you can help I will be very grateful. Hyundai accent hatchback 2014. 1.6 gasoline engine. elctronic throttle valve. when you turn on the headlights and heater, then the engine speed drops. even when you turn the steering wheel while standing still. I checked everything. ground on the engine is good spark plugs are new. the generator produces 14.7 volts. I cleaned the throttle valve. Twin quality gasoline. if possible please give me advice
I dunno. Seems like a tool that has its place every now and then but if you're not using all the time it would really slow you down when you choose to actually break it out.
I agree, learning new tech can be daunting. I actually originally made the tool to empower my Snap On scope (I'm a mobile tech, and I find my Pico cumbersome) with high end functionality that typically only the Pico can do. That said, it allows such functionality automatically, just hook it up turn it on and it outputs the signal, automatically detecing and setting the thresholds, which would typically have to be set up manually in the math channel on Pico, saving time. There are other times (like the SENT dynamic GDI test shown here), where there is literally no other way, even with Pico.
@@automotivediag8502 it's a pretty impressive tool and I'm sure it's a game changer for those who really know how to run it. Awesome work really and I hope it takes off.
I don’t know what a wps does exactly but we use it all the time for in cylinder testing This tool turns an unusable fuel rail pressure signal and converts it into a signal that we can use for troubleshooting. It also aids in misfire identification when scan data just falls short. Which comes in handy when we get those extremely light misfires It also translates SENT communication signals into a usable fuel rail delta signal, as well as Ford throttle body SENT signals, bmw maf SENT signals
@HexaNeon I looked it up. It stands for Single Edge Nibble Transmission. It is supposed to be a higher resolution and more efficient way to transmit sensor data to a module.
@@HexaNeon you can Google J2716 and see the full SAE specs, but yes it is similar to LIN, but it is for direct point to point transmission between data sensors and modules. SENT allows multiple data parameters, fast A, fast B and slow sent (typically temperature) to be transmitted over one wire with very high baud rate. Any time you see a 3 wire pressure/temperature sensor in a wiring diagram, it is most likely a SENT sensor which was the case with my Mercedes GLC 300 shown in this video.
Very good looking tool. Glad to finally see it on a pico and showing the comparison of raw signals vs the addi output. I’ll need to add it to my toolbox one day.
Honestly, that's probably the most common reason I use it, It's way faster, and I can do it on my Snap On which is much easier to grab. I'm the local mobile guy, and I find my Pico to be cumbersome.
Yes 2017 is when I first saw SENT on both Ford and GM, EcoBoost Throttle Position Sensors, and fuel rail pressure sensors on GM, which is what prompted me to add the SENT decoder to the project.
@@automotivediag8502 Does this meen it can decode the throttle sensor as well? Or ALL sent sensors? Is there a sent standard that all the manufacturers keep to, or are they all on doing their own version of it?
@@stevejakobsen2765 Yes, the device has what I call "Arbitrary Mode" for SENT where it samples the Min and Max of the binary and outputs an analog signal proportional to the full range so it makes the SENT output look exactly like an analog sensor. (I demoed this mode at Vision using a Ford EcoBoost throttle body) J2716 is an SAE standard so the device has worked on every sensor I have tried it on.
@@stevejakobsen2765 That is correct, J2716 SENT is an SAE standard that manufacturers are using for point to point serial transmission between engine data sensors and control modules. Because it is standardized, and the ADDi decoder closely follows the J2716 standard, it works on any SENT sensor. At Vision, I demoed the SENT decoder in "Arbitrary Mode" function on a Ford EcoBoost throttle body, and showed the serial input signal and decoded output at the same time live, literally making the SENT throttle position sensor display as if it were an analog signal like you would typically see on a TPS. In this video, we are seeing the SENT decoder operating in "ZOOM" mode which works with the hardware filter amplifier and highlights very small changes in the decoded binary signal from the sensor allowing for this dynamic GDI testing which would not normally be possible otherwise. I am currently working on a recode of the internal firmware that will allow the user to select either SENT A or SENT B for display in either "Zoom" mode or "Arbitrary Mode" depending on which type of SENT sensor you are attempting to test. As is the device only outputs SENT A which for this type of testing is really all that is needed, though the decoder has always decoded both channels internally.
@@automotivediag8502 Nice! I feel this thing should find its way into my toolbox in a not so distant future. Nice work! How about sent cranksensors? Same deal i suppose where its just converted into an analog signal(?)
Can you reset a AGR Valve using a Scan tools ? How do you test a AGR Valve ? Can you test it with a Multimeter ? I think AGR Valve needs to open and Close ?
so when do we get an ADDi giveaway Mario? and can you give a brief description of these sent(?) sensors that you are talking about. What makes them so special? I have never heard of them.
Just effing google it...its a communication protocol that is becoming more common, at first glance it looks like a linbus, but its actually different. The point is that devices that use this type of communication no longer have a linear output, like for example a pressure sensor signal, but its now a communication signal. The ADDi translates the comm signal to a usable linear signal that we can use for diagnostics. Pico has an article on their website that deals with Sent protocols.
Manufacturers are using SENT because it enables them to combine multiple different signals from a sensor on one wire, saving cost. Digital signals are also basically immune to electromagnetic interference as the data is transmitted by full high to low transitions rather than an analog signal which is highly susceptible to interference. As mentioned in another comment, Manufacturer started using SENT in about 2017. Newer cars often have as many as 5 SENT sensors on board.
I have an Audi 2018 Q3. I went to Audi to get the oil changed. They are unable to open the hood. They have tried everything they think they know and suggest breaking the hood to open it. It does not make sense to me. The repairs will cost 1000's$$. What Tips can you offer? Or can you please make a video about it?
You need to ask why is it broken is has the cable broken or is it the latch? Sometimes if you pull the hood open handle and hold it you can have an assistant bang his fist on the front center of the hood where the latch is and if it’s a stuck/seized latch it will pop open. If the cable snapped which is rare then you have to start breaking stuff
What about nvh to find the noise problem such as flywheel vibration or other noise we try to find can addi do that? It would be a huge benefit to deaf technicians like myself and also as mobile mechanic business owner
No, es más bien una herramienta para monitorear la uniformidad de los inyectores de alta presión. Monitorea la frecuencia y los esta deduciendo en tiempo real para ver problemas, suena como que puede tener buenos usos pero menciona que es necesario tener una captura buena del carro para ver si hay un problema en la señal.

I have tried that, the couple of times. When I did it the pressure dropped very fast and the car stalled. I had a hard time getting a stable reading.
