RPM output - pulse vs freq
Posted: Thu Jul 22, 2010 2:09 am
changed ECUs -= the old one output to tach and i paralleled off that and into DL1 RPM input, worked all fine.
The new one has what the factory manual describes as going up to approx 5 volts during operation.
Aftermarket tacho works, DL1 doesnt.
I'm thinking that the 5v signal has a freq in it - should I connect to a freq input and adjust accordingly? I'm about to go and do this, just thought that I would ask and see if I am missing anything.
Cheers
