Has anyone else experienced problems getting their PMags to enter into program mode for timing purposes? I had dual PMags installed on my engine when it experienced a tear down/rebuild resulting from my 2022 prop strike at AirVenture 2022. Picking it up in March this year I flew it home without any issues. In May I was experiencing a 200 rpm drop doing the mag check. When checking the PMags at that time the left PMag wouldn’t enter into “program mode” so after a few calls with EMAG I mailed the left PMag back to EMAG for warranty work. I was very pleased with the turnaround and it’s subsequent operation.
As some of you who have followed my VAF posts, I have experienced high CHTs and attributed this to the switch to electronic ignition (PMags). In efforts to lower my CHTs I tried “clocking” starting at 2* and later up to 7.5* ATDC. This didn’t lower my CHTs enough. Eventually I bit the bullet and replaced my original rubber baffling with new mil spec silicone baffling and eliminated all possible air leaks around the upper baffles and fabricated two air dams to direct more intake air to the back cylinders. This baffling work significantly improved CHTs so at this oil change I decided to return the timing to 0* TDC as stated in the manual.
When I went to program the timing I again experienced a PMag that wouldn’t enter into “program mode”, this time the right (other) PMag. Frankly this both surprised and annoyed me. Again EMAG, after several tech calls to test the mag they recommended I send it back for warranty work with I did this morning. I expect, as before, they will quickly service it and return it promptly. Their tech support is very good.
My question is: how many of you with PMags have experienced problems getting your PMags to enter “program mode”? Am I the only person who has experienced this problem? Is it possible that I am the only one who has experienced both PMags requiring warranty work? The first one experienced this at around 8 hours. This second one has 46 hours.
