I have done the search and read what’s available but I can only interpolate some of the information to my plane and installation. I’m planning on replacing my left mag with a SureFly electronic ignition. The left mag is the more difficult to replace and my right mag runs the smoothest of the 2 so that made the decision easy. Having 3 mag failures in various planes and a recent defective mag that caused all kinds of expensive trouble shooting and unnecessary parts replacement for my engine monitor, I’m hoping this is a good solution and not just going to create new problems. I’m also looking forward to the potential high altitude performance gains with the variable timing(mixed reviews on this), smoother LOP operation(positive reviews), no 500 hr inspection and the 2 lbs weight savings. One concern is that people with 24V systems have been having more problems with the surefly. Most seem to be related to other airframes installations and not running the power directly to the battery. With the Mooney that means a long wire run through the cabin. I was wondering if anyone is currently running the surefly on a long body(24v)has had any problems with the unit and it’s power source? From what I understand the system reset itself if there is a slight disruption in the power supply and this seems to be less of a problem with the 12V applications. The mixed reviews with the variable timing seems to be related to the Improper installation of the power source on both the 12 and 24V systems and improper setting of the initial timing with the hardware. Another concern Is the RPM pickup with the EI MVP-50. It looks like it reads RPM with 2 channels, 1 channel going to each mag connecting to the P-lead with an isolator and picking up the pulses. With the surefly the EI installation manual says it doesn’t need the isolator since the output is not such a high voltage that will damage the MVP, I just wanted to see if anyone has experience with this and if the hook up was as simple as removing the isolator? I will call both companies on Monday to verify this but wanted to start my install this weekend. Thank you
