... have a concern as we are approaching the maximum input pressure of the WPS500X (500 PSI) Would it be possible to disconnect the injector before starting the engine and ...

Thanks alot, very good PowerPoint !
And very intressting link, thanks for that, i didn´t find that...
I will take a few samples and put them here when i get the chance.

Thank you Terbo and Henri for the posts and presentation. With reference to Can someone explain how to set up the Pico and WPS500 to get a reading for Exhaust-Pressure at the Tailpipe to determine what Cylinder is misfiring ? Could you take a look at the thread below that does go into the complexiti...

... succeed in interpreting the exhaust signal of my Rover V8. I use a WPS 500 on the zoom function 2 with an Owon scoop. I tried to put a powerpoint with a few slides ...

Can someone explain how to set up the Pico and WPS500 to get a reading for Exhaust-Pressure at the Tailpipe to determine what Cylinder is misfireing ? I am using the Menu-Settings given in the Pico-Software sofar... I tried with many Cars, but i can´t get anything what i understand as far as knowing...

Try to do an injector voltage test on injector three. I am thinking of a stuck open pintle in injector 3 (no hump at end of waveform). If so, try to tap injector with screw driver while re-scoping and if hump appears then it confirms a stuck pintle; cleaning or replacing is an option...

I would love a wps 500 pressure transducer but the main dealer I work for has to have a picoscope but refused to buy one so I bought ...

... if you could carry out a compression test, especially if you have the WPS 500 pressure transducer? If not, using a conventional gauge would help and once we know the ...

Robsky: my scanner and exhaust pressure both indicate cylinder 3. I tried all possible settings of my wps. Maybe also the pressure regulator is stuck. I have no reference waveform except one on this Pico site.

Arian: access is difficult, connection is about 20 cm. It is a wasted spark ignition. Same coil for cylinder 3 and 2. I didn't do a leak down ore compression test, but MAP with my scanner was OK.
