Hi,

I am in the middle of wiring my 0.4 board to an MX5 VVT in an NB1, with weird wiring. But I won't bother you with those details, but I would like a running signal to check / control some things. Can Speeduino set a pin high when running, not cranking? My other option is a simple power voltage measurement, when above 12,5V the alternator is charging, so the engine is running (my alternator is switched off under cranking). But a simple pin on the Speeduino would be nice.

Thanks,

Hugo

Thanks for the replies. I just remembered the fuel pump relais is triggered above a certain rpm (when cranking and running). If I combine that with the crank signal (if crank is low and fuel relais is high => engine is running) I have what I need.

Cheers,

Hugo
