Fuel consumption

Hi,

I have a M130 with GPA package and would like to calculate the fuel consumption of the engine. M1 Tune offers a channel for 'Vehicle Speed [km/h]' and 'Fuel Volume [uL]'. How can I add a channel, that applies a filter to Fuel Voume and prints the fuel consumption [l/100km] ?

Thanks!

Hi,

This is not possible in the M1 unless a custom firmware is made, it is possible to be done in i2 and some of the Dashes.

Hi Stephen,

Alright, I was already afraid of that. But as I want to read out the Fuel consumption via CAN, I could also calculate it externally. Therefore I would need to know, if Fuel Volume and Speed are transfered automatically via CAN and how I can find out their adresses. Can you give me a hint where I find Info about that?

Thanks,
Kilian

Kilan,

In my GPR-based firmware M150 there's an "ECU Fuel Used" in the output CAN stream. I pick that up in my AiM MXS dash and display it. That's the fuel used since the ECU was started. There's also an ability to calibrate that (via %modifier) in Tune for better accuracy. I use this on my Radical (which doesn't have a fuel gauge) to keep track of fuel used over time.

That ia a great trick.
