I installed a P and E about 10 hrs ago to "EXACT" installaton instructions and may be the "1" still experiencing the intermitent miss. Flew 3 hours this week in sub-0 temps and had some misses but nothing serious enough to cause alarm.
Brad and Tom are helping to identify the source of this issue and have offered replacement of one or both units. I have not been able to acertain which unit is causing the miss and am test flying under different modes for that purpose. I.e., ignition set to 'both' , 'L', 'R' and the Pmag circut breaker on or off and the aircraft alternator on or off can offer multiple flight modes that may or may not contribute to or assist to identify which unit is causing the miss.
Miss is probably not the best term to use either, but more of a brief 'stumble'. It gets your attention for sure, but seems to effect only one plug. The other plug (opposite ignition) still fires and for that reason it is hard to call it a 'miss' in automotive terms. On Monday, I will call Brad to give him the 'numbers' of the units in order to determine the mfg. dates. I may have a unit that was built before the fix and will have to do the exchange.
