I have always fancied myself an ok wrench turner and a novice level electronics enthusiast, but trying to accurately pinpoint issues in the CAN systems or anything with a PWM drivers has been beyond me for a while. I am looking at getting an oscilloscope, but between all the money I have to pour into my OWN truck, and all that I have spent so far, I don't think I am ready to swing several thousands again (check your u-joints....your entire driveline will thank you hahaha) What would be a good 2 channel scope (minimum?) to get my hands on in the $200 ~ $500 range? I was at first opposed to PC based scopes, but now looking at the software available, and having used my Flashscan for EFI tuning, I have really grown to like multichannel diagnostics, as well as having a larger screen to make sense of all that data at once 😅

Here is the short version. I was six months old when my father died, had an abusive step father from age 6 to 15. Hated everyone and everything, used drugs to find a happy place, took 15 more years to kick it, found a new "high" and that is through my Lord and Savior, Jesus Christ. Somewhere in the middle of all of this I found my love for electricity and electronics. I can do all things through Christ who strengthens me. Philippians 4:13 I am nothing on my own.

First I would like to point out that there are teachers and then there are teachers. You are a teacher in the truest sense. Someone can know everything there is about a topic but not be able to convey it in such a way that you get it and want more of it. That is a true gift. Though I did drivability work at the dealership in the early GM computer days it was not with this kind of understanding. My primary specialty has always been automatic transmissions and few have looked at waveforms for diagnosis. I briefly touched on it about 15 years ago in a simple on/off solenoid (as opposed to a PWM controlled). It does occur to me that though on time is measured in millivolts, in reality it appears that it is less than that due to the pintle opening once it reaches sufficient magnetism to actually move the pintle. However, I see the closing on the voltage scale (something I did not know about at that previous time in my life) and it seems like the "On time" and the area where the pintle is open are very similar, though slightly shifted start to finish. Obviously strictly an engineering issue, similar to whatever motivated the designers to use a particular type of injector but a matter of curiosity just the same.

First of all: another great video ! You can also find a different design of peak n hold. Aplying full 12V for about 1-2ms and then changing control voltage to PWM mode to maintain injector open and limit current dynamically. Commonly used with low ohm gasoline and LPG injectors. Zener diode you said about is actually a transil or TVS diode.

You can perform this test on any port fuel injected system that uses a saturated switch injector (which most do). I am not sure if you would want to use this timer tool on a peak and hold injector. Fortunately I cannot remember when the last time I saw a peak and hold injector on a PFI system. As for using the current clamp on anything with less than one amp you will get some noise in the picture. You can try filtering it and also moving it away from any ignition components

In my design days at IBM we had several ways to reduce the pick time of an electromagnet. We used them on clutches, print hammer actuators etc. The simplest was to use a capacitor in series with the magnet coil and a resistor in parallel to the capacitor. When the switch closes, the current is only limited by the capacitor with is near zero resistance initially. When the capacitor gets charged the current flows only through the resistor which provides the hold current. When the switch opens, the capacitor is discharged by the parallel resistor. We also used flyback diodes, usually in parallel with the coil to quickly collapse the magnetic field. It would be interesting to see what is inside the PCM for pick and hold systems.
@cyborgdale11 жыл бұрын
I can explain why the Honda injector has the series resistor and opens faster. Inductors (coils) resist changes in current. The larger the inductor--the longer it will take for the injector to saturate (coil to reach maximum magnetic field and open). Placing the resistor at the coil limits the maximum current cheaply. The low inductance allows the injector to open quicker. In a Peak and Hold, the inductance is also low and therefore opens faster. (continued)

I have seen you videos of you showing the ignition coils waveforms and injector waveform but never the spark plug waveform any reasons why?
@cyborgdale11 жыл бұрын
(continued) With the Peak and Hold, the current is allowed to spike higher initially for a short duration causing the coil to saturate faster and then quickly limited to a lower value. This current control is done at the computer. Looking at the total ohms is somewhat misleading as this is a coil (solenoid, inductor). When comparing injectors, it is better to think of total impedance (inductive reactance + resistance). You can also measure the inductance value.

I would assume that it's either losing a power or ground for the drop out and drop in, but what's weird is the amperage waveform does not drop out. Ok thanks. Found where I can edit. My original question was that why was my amperage waveform dropping out and in when I had the trigger right on the middle of the waveform, but I think what happen was I adjusted either my time base or voltage ,and the scope automatically changes the trigger from normal to auto or single, and that was causing the waveform to look like it was dropping out and in. Next day I tried it again and made sure I still had a normal trigger. So now I'm a little confused on why I'm getting only about 1 Amp on the feed wire for all the fuel injectors. At first I was thinking " ok this circuit is a parallel circuit, and should be getting around 4 or 5 amps being that it's a 5 cylinder, but then I said " this is a sequential fuel system so each fuel injector is a series circuit, and spray in sequential order, and that's why I'm only reading about 1 Amp on the feed wire to all injectors. So just wanted to ask if I'm correct on thinking that the fuel injection circuits are each a series circuit ?
