Adding VR conditioner to UA4C SPEEDUINO (open source ecu)

• Combining Arduino with...
In this video we add a Mini MAX A2 Signal Conditioner (VR) from wtmtronics to our UA4C speeduino. We set our trigger settings in tuner studio and test the RPM1 input with a distributor!

Your „Distributor“ sends out a hall signal, you dont need a vr conditioner. Set jumpers to direct and pull up

Hey! Thanks for reaching out and letting me know. I tested with a multi meter and I'm getting some ac voltage when connecting to the 120 degree signal and the negative then rotating. Also it produces a RPM reading in tuner studio. If I remove the VR conditioner then jump direct and pull up as you say I no longer get an RPM reading in tuner studio when rotating. The meter test suggests its a VR and it does work seam to work in the VR configuration and described. I don't doubt that it maybe a hall signal, but why then I'm not getting a RPM reading when setting it up as you specified? What are some other things I can check to verify?
