Hi,

The first waveform is from a Audi 2.0 TFSI, the car with no any problem.

Hi Kim,

The first waveform is from a Audi. I am not sure the car have a specific problem. My customer sent the waveform to me, and I still contact with him about this.

Many thanks for you document, I am reading it.

Hi all, Could somebody here tell me how to judge the open time for GDI system injector? There should be a point on current waveform show the injector is starting to open. But I can’t see it on my waveform. I guess the action of GDI is very very fast, so we can't see the point. 2.jpg And regarding to...

I remember some one taught us how to caculate the total record time of PicoScope. There is still one thing I am not very sure about. So come to here to confirm. Just make one channel in using for example: I set timebase as 5ms/div, sample number for one screen is 1MS, capture rate is 20MS/s, Pico442...

Hi Also trying to decide what Pico would work for my needs. My main working area is not Automotive, but in fiddle with Cars in my spare time. My real work area is more IT and Electronics. My question is: 1) What is the difference between 4423 and the 4424 ? 2) Would PicoScope Automotive software wo...

Hi all, The waveform is captured from a distributor ignition system. Ch A is from cylinder 1 plug lead, Ch B is from distributor King/main lead. We can see from Ch A that the cylinder 1 have a ignition fault , its burn line is not almost horizontal, and have a bad coil oscillation. But the waveform ...

Hi, How can we understand what is 1 ° - 2 ° - 3 ° -4 ° cylinder? Sorry for my bad English briefly disable one cylinder，unplug its injector maybe, you will see one bar drop down. Then you know the bar represents the cylinder you disable. And the rest bars are just in firing order. My English is bad ...

seems that the size of the data file is too large for the forum, 14.3MB, cann't upload it.

My PicoDiagnostics version is: 1.4.55 build 6. I found that I load a same data file for several times, and it displays different results at first screen. I will upload the file here. You can load it and close it for several times. Sometimes you need to shut down the whole software. image001.png Fig....

This is Eric Chen at Hongke from the other side of the world, China. I wrote this for my customers in my world. They don’t have a good understanding for PicoDiagnostics software and because Pico is improving it and add some new features usually, they may ask any kinds of questions. For them taking g...
