In this video I compare the "flagship" Pico WPS 500x to a few much less expensive pressure transducers. The sensors used in this video are around $150 or less (June 2022). I demonstrate the pattern with each sensor on a 2016 Chevrolet Silverado with a 5.3L engine. Also, while I have the sensors hooked up, I compared the pattern from a highquality 12bit Pico 4423 to a much less expensive 8bit Pico 2204a ($150) to see if you can perform incylinder pressure testing with a less expensive scope AND a less expensive pressure sensor.
