Calculated fuel consumption?

Hi all
Not sure if i need to post this else where but this was my best guess.

I am wondering if it is possible/ if anyone has done it/ or what the process might be to. Have a mk2 pro measure injector pulse width, duty cycle, and fuel rail pressure then display a calculated fuel consumption value.

Or if you have a alternative solution I am open to suggestions

The car is equipped with
A 034efi 2c stand alone ecu
Oem fuel cell and modified fuel deleiver system.

There isn't a way to measure duty cycle, but we do have a different suggested way of doing it, via direct measurement of fuel flow: ... telemetry/

If you have a return-style system, you'll need two fuel flow sensors.

For doing it the way you suggested, an external device that can calculate duty cycle on your injectors can broadcast that via CAN bus to RaceCapture. This would be a good candidate for an arduino project.

Hope this helps!
