FirstLook Engine Diagnostic Sensor

The Firstlook is a pulse sensor, not a pressure transducer. If you need to measure pressure, have a look at our WPS500 kits here

The FirstLook Engine Diagnostic Sensor offers a fast and accurate method to diagnose automotive engine problems such as burnt valves, bad injectors and other performance problems without major disassembly of the engine.

When connected to the exhaust or vacuum side of the engine to be tested the FirstLook engine diagnostic sensors enables a mechanic to quickly display a complete picture of core engine performance on a suitable digital storage lab scope.

The FirstLook sensor requires no external power source and is particularly suitable for use with a PicoScope automotive oscilloscope but can also be used with most other modern lab scopes.

This little device produces the cleanest vacuum and pressure pulse waveforms I have ever seen.  It has a vacuum nipple on one end with a BNC connector at the other end for plugging directly into a scope.  It requires no batteries or external power supply hook up.  The device is extremely sensitive and has a very fast response time.  It can be used to view engine vacuum waveforms and also exhaust pulses to aid in identifying mechanical breathing problems with the engine.

There have been many home made and manufactured attempts to make a tool that will do this well.  Nothing I have seen compares with this tool.  As many of you who have worked with engine vacuum waveforms know, interpretation can be a complex issue and many engine design variables can affect the results.  So, the learning curve on this can be a challenge.

As I was reviewing this tool, I put it to a use not originally intended by the manufacturer.  I placed it on a fuel pressure regulator nipple with the engine vacuum hose removed and plugged.  It produced the most highly defined and clean injector pulse waveforms I have seen anywhere by picking up on the minute diaphragm oscillations resulting from the fuel injector action.  Each individual injector pulse could be seen clearly.  This could be a real time saver on many applications where injector flow issues are suspected.  Here are some examples:
