Viewing Fuel Injector signal's
Here is a basic injector signal, scope gives on time, and peak volts.
If you use the other channel, you can get more measurements.
If you add another signal, in this case the MAP signal, you can see injector on time following the MAP.
How about a crank sensor and fuel injector? 95 Jeep Grand Cherokee 4.0L engine, triggered off the number one injector.
Peak and hold injector, 90 Chev S-10 2.8 TBI. My Fluke won't calculate ontime. Fluke 98 Series II will.
