    Firstlook pulse sensor.

    Anybody has experience in using this sensor?
    How good is it in diagnostics?

    There are two versions of this tool. One that is mainly for the tail pipe, but can be used on he fuel rail if there is a fuel pressure regualtor on it. The second is strictly for the fuel rail,that hooks up on the pressure test port, which one are you interested in?

      1st look sensor

      I've had both sensors for the last 2 years, I use them almost every day, once you get uses to them their great. would'nt be without them.

        Could you post some snapshots. I'd like to see how useful it is.

            1st look sensor

            001 is a fuel inj test, trigger on #1, injector #2 bad (missing) firing order 1342, sensor attached to fuel pressure reg.

            002 is exhaust waveform, all 4 cyls firing good.

            senxtech.com has some good examples of waveforms some with Modis, its as good as they say it is. I would start with the pulse sensor and see how you like it, you won't regret it.

              Channel 1 is Cylinder #1 fuel injector firing
              Channel 2 is a current ramp of all injectors
              Channel 3 is the First Look sensor. This is the first version on the fuel pressure regulator, note that the fifth cylinder is slightly weaker then the rest. This is a great tool but it has a BIG learning curve. You will need to practice on known good vehicles to see how different systems show different patterns. This version will also NOT work on returnless systems. That is what the second version is for, restrictly fuel system testing.

                Exhaust waveform, trigger #1 ign, misfire on cyl #2. On exhaust waveforms you have to off-set the firing order by 1 on 4 cyls, 2 on 6 cyls, 3 on 8 cyls. Example 134(2) becomes (2134). As Steve6911 said it takes some practice, I took a good running veh and disabled different systems. good luck.

                      This doesn't requires external power source and is particularly suitable for use with a PicoScope automotive oscilloscope. People who need services in Automotive can post their request on Mineeds.com and providers will post their bids on your needs.

                        This looks like an easy way to catch a dead injector -- but do you have any examples of restricted/partially functioning injectors? Incidentally, what was the specific failure in this image? Was it an electrical or mechanical issue with the injector?

                        Thanks.

                          go back and look at my second post in this thread. The 5th cylinder injector had a low flow condition (channel #3).

                            Excellent! I must have missed that post. Thank you.

                              Several Russian-language sites is a new method of working with Firstlook sensor . As it is quite possible to accurately diagnose the state of the timing diagram & condition of valves . One of the producers of the Autoscop include the method of determining the phases of the program. Also, self-produced Firstlook sensors cost in 5 dollars. And the cylinder pressure sensor not much more expensive
                              Of the deficiencies can be noted the need to experience .Metod spent only four cylinder engine.
