Use your lab scope as an on-car flow bench!

The FirstLook Injector Diagnostic Sensor is a universal tool that can be used with virtually any:
-- multi-channel scope, and
-- fuel pressure test adapters (the ones you already have)

It connects to the fuel injection rail and produces a signature from all the injectors on one scope channel. The uniformity, or lack of uniformity, of the signatures will let you determine which injectors are flowing and which are not.

Will it work with vehicles that do not have fuel pressure regulators? YES.

It connects to the FUEL RAIL via the Schrader Valve. The kit includes Quick Disconnect Adapters to make this connection. If no Schrader Valve exists a Schrader Valve must be installed before testing the injectors.

This screen capture is from an idle test of a 1996 Accord 2.2 The bad injector is easy to spot.

Injector pressure is sensed and the voltage is output for display by the lab scope. Using the ES-300 in conjuction with ACE Misfire Detective software can quickly and easily trace back injector problems in the engine to the cylinder they originate from!
