Want Output to Mirror Input

Recommended Posts

Your right Adam and I maybe just making things a bit complicated.  I have a data logger picking up some information from the ECU.  The normal way is to splice it in but if I wanted to get different info I then have to rewire as opposed to altering the program.  So for example I may allocate a couple of outputs that are to feed data to the logger but may change what they are sending out.  For now while I am sorting out the gear change it maybe load cell etc.

The proper way to do what you want here would be via CAN...

The digital on/off type inputs you should be able to work out easy enough but the analogs will be a bit more drama.  There are no built in "analog outputs", so if you want an analog output you would have to use a PWM aux out, then convert that to analog via a resistor/capacitor network.  That would possibly add some delay to the signal and it would take a fair bit of messing around to work out the calibration etc.
