Hi all.
I would like to grab some values from rusEFI to print on my display. do I need to send a request or can I just listen in? what nitrate and stuff should I use?
cheers

I would like to read vvt position on my display and (if it's doable) receive map from gpio (akthough mpx4250s are quite cheap so no biggie)
the other alternative is to send serial commands and read in what comes back - not sure what the command is on rusefi though .

ok I have found the obd2 stuff so I'll have a read. looks like there are only a few pids but good exercise to read those I guess
