Greetings!

A request for some data from scan tool for folks with a TDv6, a scan tool capable of monitoring/graphing PIDs (Parameter IDs) from the PCM, and some free time.

I am trying to troubleshoot a strange problem of fuel rails becoming over pressurized as soon as the engine is started. Issue mentioned in this rather wordy post: https://www.fullfatrr.com/forum/topic73394.html

I am looking for the following PIDs from the moment the engine is started and for about the first 30 seconds of its initial running.

1. Fuel Metering Valve duty cycle
2. Pressure Control Valve duty cycle
3. Commanded Fuel Rail Pressure
4. Actual Fuel Rail Pressure
5. Pressure Sensor Voltage
6. RPM

Let it idle with no throttle application for the first 15 seconds and then give the engine a couple of gentle revs to 2500 rpm.

It doesn't matter if the engine is cold or up to temperature for the test. Would just need to know if it was cold or up to temperature.

If your scan tool cannot save numeric or graphical data then a cell phone video of the screen of the scantool showing the data would be great.

The PIDs listed above are in order of priority. So if the screen of the scantool is too small to fit all 6 PIDs without paging up/down then #6 and if needed #5 can be dropped.

Thank you!
