Portable engine test tool with additional accessories
Essentially, the CarScope i-Testeris a specialized type of engine analyser. It is a complex, multi-function tool which can assist engine diagnosis and find engine problems. i-Tester can be used on both gasoline- and diesel-powered vehicles.
Currently, there are 2 modes available: the relative compression test and the Common Rail pressure test; several automated diagnostic tests are upcoming with future firmware updates!
No oscilloscope knowledge needed. You can skip training and the preparation time of an ordinary oscilloscope and directly start a quick, precise engine analysis.
- Non-invasive test
- Test is completed in seconds
- No pressure transducer required for relative compression test
- No mechanical work required (no removal of spark plugs, glow plugs, injectors prevents damage to engine components)
- Simply disable the fuel system to prevent engine from starting and flooding the cylinders
- No oscilloscope required
- No previous skills required
- No waveform analysis knowledge required
- Based on scientifically backed theory

- Works with 3, 4, 5, 6, 8, 10, 12-cylinder cars
- Works with DIS, conventional and Coil-on-Plug ignition systems
- Only 12 V electrical systems are supported
- Excellent industrial design
Reasons to perform a relative compression test using i-Tester
A compression test has to be performed when the engine shows the following symptoms:
- Engine misfiring
- Rough idle
- Loss of power over time
- Unexplained loss of power
- Smoke from the exhaust
- Puffing noise in induction or exhaust
Check the engine health in the following cases:
- When buying a preowned vehicle
- Before ECU remapping to evaluate engine status
- Periodic prevention check
- When it is challenging to access the spark plugs in order to perform a common compression test
