Replaces 6-cylinder magnetos on Continental engines. 5.0 lbs.
I have two airplanes. I installed the Surefly my with supervision. First my Cessna 172. (E2D) works perfect. More power , better lean performance, less fuel burn , easy to install. Next installed on my A-36. Easier starting, 1.5 gallon less fuel burn. The Surefly is the best upgrade for the money in my option next to gami injectors. . The tech support was perfect. Ask question at Surefly, tell them what tach you gave etc. saves time and effort.
Works as advertised. Instructions are very good. It recommends you change the ignition harness. I checked my ignition harness and found some opens in some leads so I changed it. The difficulty I had was emplacement. It is a large magneto. Emplacing it on an IO-470V was difficult because of the low cowling clearance above the magneto. It took me several iterations to get the proper placement, adjusting the position of the drive gear. I was unable to hook up the vacuum line because the IO engine has fuel injectors in the place of the recommended manifold pressure souce.
There are no details in the instructions on how to connect it to the MAP system, no fittings provided at all. They should include some connections or at least a note suggesting how it can be done. Overall, not impressed with the MAP connection. The rating I give is purely based on the install experience. On contacting them they recommended a $5.00 connection on the cylinder head. Why not just include that in the kit? A: Too many variations in installation to manage that. My response: Include a few of the most popular fittings if they are only $5.
Per MFG.: We are expecting the turbo charged engine AML will be here within the month of Feb. But it is not there yet, so it is not an approved installation. So in short, this has not been tested or approved for turbo engines as of yet.
At this time, the Horizon tach is not supported with SureFly. It is in the works, stay tuned.
The SIM6C is 5 pounds.
Our electronic ignitions do not require pressurization.
The JPI most likely uses the screw-in sensor on the mag for RPM. When installing a SIM, just make sure the sensor is installed on the remaining mag.
No, it just needs to be installed by an A&P if installing in a certified aircraft.
The standard mag puts out about a 300 volt pulse on the P-lead. The SureFly puts out a 60 volt pulse on top of a 10-volt DC voltage. brbr Also, the standard mag pulse rings so that some of it goes below 0 volts, but the SureFly is all on the positive side. This is why the Horizon Tach will not work without a Tach2 converter. They designed the Horizon to use the negative part of the pulse.
Battery power is required in order for the SIM to operate. We require a 14 gauge wire to be run from the battery through an inline fuse holder, directly to the SIM. The SIM does not generate its own power and requires 8 to 30 Volts to operate.
Currently the SIMs cannot be rebuilt, the disassembly process destroys the SIM. After 2400 hours the SIM is returned for exchange.
