Engine Polygraph Kit

The Engine Polygraph kit contains the basic hardware to produce digital pressure change data from an internal combustion engine (ICE), spark or diesel ignition, simultaneously in the exhaust and crankcase while the engine is ‘hot’ (running) or ‘cold’ (cold-crank). The data is collected by two FirstLook® sensors for 500 ms to 1500 ms, depending on the engine RPM. It is most useful with a four-channel PicoScope to provide simultaneous views of the exhaust, crankcase through the oil dipstick tube, and other optional sensors. The PicoScope is connected to a laptop (not included) which is connected to the Internet.

The signatures (data) are analyzed on our servers and reports generated and made available online or via email on a subscription basis.

The threaded FirstLook® sensors are attached to hoses or to various provided attachments by threading into the hose or attachment; extraction is by reverse rotation of the sensor. The hoses and/or nozzles are then placed to sense the pressure changes and vibrations. For vertical stacks, see the ‘Shepherd’s hook’ vertical exhaust sampling unit, below.

Engine Polygraph Reports
MSRP 25.00 USD/Report or $500/month with unlimited reports

What are Engine Polygraph Reports for engines of the same model with different issues.  EP Reports are available on a monthly subscription basis for your shop. Please call us to establish a unique short Company name to represent your shop and a startup sign-in username/password when you are ready to proceed.

Engine Polygraph web-based application:

The web-based Engine Polygraph application provides the functions to store signatures and reports for future reference with a search function to help you rapidly retrieve previous results. The application enables the authorizations of identified technicians to collect the data and select the desired reports that can be forwarded to other email addresses.

The billing is automated for a per-report or a monthly flat rate per EP kit. The signatures and reports from multiple technicians using perhaps multiple EP kits can see all reports under the same EP customer account.

Details on the functionality of are available in a PDF download (Engine Polygraph Users Guide).

Engine Assessments:

You may request an optional analysis of your signature if it is done according to our EP Methodology. Currently, we provide two different types of reports. The Assessment ‘scores’ the major engine components for physical integrity: each component is assigned a value from a ‘Great!’ (score = 1) to a ‘Very Poor’ (score = 9). The results are accompanied with graphics showing cylinder-by-cylinder behavior. For more information on the Engine Polygraph Assessment report, download the document “EP Assessment Report“.

Diagnostic Reports:

The optional Diagnostic report contains all the information in the Assessment report plus more data about the engine model of the vehicle and a section listing detected ‘Abnormal Observations’ (engine and cylinder patterns that are not common to a good engine of same specifications).

These Abnormal Observations are then tested against a set of rules to suggest ‘Causes’ that would produce some similar observations, recognizing that your engine might have more than one problem. The report then shows the estimated probability that the indicated Cause is present in your engine.

The report lists one or more suggestions to address each identified possible cause. Of course, we cannot guarantee that the diagnosis is complete and accurate, but that it represents our ‘best effort’ to incorporate the experiences to date from several expert mechanics.

For more information on the Engine Polygraph Diagnostic report, download the document “EP Diagnostic Report“.


Any EP subscriber can download a PC/laptop application to their shop devices to greatly simplify and pre-edit signatures before automatically send the data to our servers. The PC/laptop must be internet-connected to obtain this capability. There is no additional charge for this capability.

For more information on the Engine Polygraph Diagnostic report, download the document “EPReader Installation and User Guide“.

What is the connection to Engine Angel?

If you represent a Fleet operation, you probably know of Engine Angel (, a web-based application to provide Fleet Management capabilities by integrating data from your engines (ECM and EP), your drivers and operators, your maintenance and service activity, etc. These data are combined with weather, highway conditions, etc. to provide context to the data from your drivers and vehicles.

EP provides an interface to owners of vehicles that are reported in their Engine Angel Vehicle/Engine database. Such an interface requires authorization for the communication by the EA Fleet management.

  1. Accessories for more advanced diagnostic work (Not recommendations, but suggestions.)

Optional Diagnostics components

Radiator Pressure Sensor kit

Radiator Pressure Sensor kit to be used with FirstLook® sensor to detect pressure variation by cylinder, indicating gasket/cylinder sleeve failures resulting in pressure pulses at the radiator cap. The pressure will be displayed on the EP waveform graphic.

PICO Inductive Pickup can be used to detect spark at a sparkplug on one of the additional channels of the PicoScope. This works if your engine has a distributor wire to the sparkplug. If this is used, enter the cylinder number you are referencing on the EP screen so the diagnostic report can highlight that cylinder in the report.

15-inch WyzeProbe for Secondary Ignition and COP

Scope each COP cylinder, one at a time, and quickly with the WyzeProbe!
This 15-inch probe makes it easier to access the coils.

Non-Invasive Current Sensor - 30A

Non-Invasive Current Sensor – 30A can be used to measure the current draw during a cold-crank (‘c-c’) test. The simultaneous current will be displayed on the waveform graphic.

Bluetooth OBD-II Automotive Scan Tool

Bluetooth OBD-II Automotive Scan Tool can be used to use Bluetooth to transmit the rpm, odometer, and coolant temperature to the EPReader.

5-Gas Exhaust Analyzer

5-Gas Exhaust Analyzer (IR Infrared)  to capture the data from your engine exhaust. The data can be entered into the EP application or transmitted via Bluetooth if your PC is so equipped. The data is ‘attached’ to a previous EP signature and can then be included in the diagnostic analysis.

  1. Miscellaneous Products

Engine Polygraph Cable-Org (SKU 20014)
MRSP 16.95 USD plus shipping

The Cable-Org (organizer) unit is a simple device for wrapping, storing, and unwrapping cables and cords. It is designed for managing two rg 58 coax cables of up to 50′ each. Displayed (left) is a unit with one 15′ and one 25′ rg 58 cables as typical for the EP kit (SKU 20010). One unit is included with each EP (20010) kit where a ‘loaded’ unit fits snug in the 5010 case.

The ‘two handle’ design allows easy wrapping of each cable, one at a time, preventing the typical twisting and knotting of the cable/cord that complicates the next unwrapping. The holes at the tips enable hanging the unit on a wall. Works great for power extension cords and holiday decoration lights.
