This past weekend I did something that really caught my (and especially my wife’s) attention. I have an O-360-A1A with duel P-Mags. I have an engine Bridge controller on the P-mags ( https://www.enginebridge.com/product/engine-bridge-ei/ ) that sets the advance, and can also be used to monitor the mag temperatures. It does both via a Wi-Fi connection with my i-phone. There is a waring in the instructions that sending new setpoints to the p-mags while the engine is running will cause a quick studder in the ignition. I have done it, but prefer to send the updates before start-up.
This weekend I was cruising along at 9,500 FT, 2,600 RMP, 8.2 Gal LOP. I decided to look at my mag. Advance and temperatures. I then saw an option for viewing the prop position. I have not used this feature before, so I pressed on that button. About 2 seconds later the engine began to misfire. I went full rich and backed off of the throttle, but it continued. The last thing I had done before this was to try looking at the prop position, and I remembered the warning about sending new settings, so I closed the Wi-Fi connection to the Engine Bridge and the misfire stopped. In all, I think it lasted about 10 – 15 seconds, but my wife’s crying went on for a good 10 minutes.
Just passing this along for others to learn from my mistake…
