Ignition waveforms can identify engine drivability problems, but modern Coil On Plug (COP) systems have module drivers built into them so they have no primary waveform. This makes diagnostics difficult.

The ECOP quickly attaches to the coil housing or ignition wire capturing a clear ignition waveform; making problems quick and easy to diagnose using any oscilloscope. Only 1 ECOP is necessary, but to take full advantage of all your scope’s channels consider a set of ECOP’s.
