Thanks for the post, agree with your thoughts, I find it useful to use scan data for smart sensors and if possible export the data into a spreadsheet for review.

My 2 Cents, in no specific order, put new batteries in (or a good charge), clean the cable connections, don't think this is the problem but would be good to know if this is what is driving the apparent low volts on the fuel PSI and any other questionable results between the two machines. Continuing ...

Capture.PNG Thanks again for the help, I contacted the company that sells the meter and included the full specs they sent, looks as though Steve's research was spot on.. Features : … Diesel and gas application … 2.0 – 30 liter/hour flow rate … Accurate and reliable 2.0 Electrical : Supply voltage :...

Thank you for the math lesson, can I assume that if I want the reading in ml/m I would drop the /1000 off the end of the formula..?

Recently purchased a flow sensor FS-3400AH from Futurlec, specs are limited, 0.05-0.5 LPM with an open collector output. It's a 3 wire flow sensor (+/- and signal wire), compatible with gas/diesel, have manged to figure out that in order to generate a usable waveform the sensor signal output and pow...

I would start with the basic settings, take a pic with your phone an upload would be an option or just a shorten the recoding.

Ran into this quite a bit, can’t say for certain how to determine can overlaying but what we typically found was improper connection of aftermarket components, anything from scotch locks to removing termination resistors and tapping into the harness ends.

Thank you Steve, appreciate the breakdown of the capture.

Guess I’m missing it, your capture settings look Like the trigger did exactly as it was set up to do.

Not familiar with this engine but I would won’t to see the control side of the fuel rail pressure and verify upstream of the sensor is not influencing your trace, I would agree it appears that the signal is dropping out. Does it have any audible or visual indication of fuel pressure actually droppin...
