Spliting analog output signal (0-5v) to two inputs.

[jamesm]

Is there scaling in the p3 gauge to display the value properly? It's just a simple 0-100%, 0-5v linear output.

When setting up the gauge you set the value the gauge will read at 0v and the value it should read at 5v. The zeitronix specs on the kit shows that the analog out line is a linear plot ethanol content = voltage x 20. The gauge should work fine in this application but I dont think it has the ability to exponentially scale up.

So yes, you would have to splice into it and connect it to the ECU AND the P# gauge analog input. Not a big deal and doable.

Thanks for checking it out Dave!

To simplify things a little more I gave Mike a call like you said. In my kit hes going to send out the ECA2 instead of ECA(1). The ECA 2 has two outputs and doesnt come with a display just the analyzer. I got lucky he had them in stock.

Awesome! You are good to go then
