I have recently installed the engine bridge controller on my P-mags. https://www.enginebridge.com/product/eiwifi/
I love it. - very easy to install, and takes no panel space. I can adjust my p-mag timing from my cell phone or I-pad, and I can monitor the internal temperature. All if this information can be sent to a Electronic Flight Display, but I am just viewing it on my phone for now.
Question: What settings are most using for an O-360-A1A?
