SUREFLY SIM6L 6 CYLINDER LYCOMING MAGNETO REPLACEMENT
MFR Model# SIM6L
Now approved for many turbocharged twins and most 4- and 6-cylinder Continental & Lycoming powered aircraft.Replaces 6-cylinder magnetos on Lycoming engines. 5.2 lbs.
Note: Surefly strongly recommends the customer purchase a NEW slick-style harness and fresh spark plug set with every SureFly SIM.
SureFly is an FAA certified electronic (solid state) magneto replacement. The SureFly Ignition Module replaces one magneto - generally the left or impulse-coupled/starting magneto on most aircraft. 4 and 6-Cylinder models are available for Lycoming and Continental engines.
Replacing just one magneto eliminates magneto maintenance and cuts associated costs in half! Zero maintenance. Zero rebuilds. Zero overhauls. Most fixed-wing single engine aircraft can enable SureFly's advanced timing feature for improved cruise flight efficiency. Many other aircraft will be able to use the advanced timing feature as the FAA extends SureFly's Airframe STC AML.
For SureFly customers, 500 hours is simply not good enough. SureFly Ignition Modules provide operators a 2,400 hour operating service time. No inspections, no rebuilds, no overhauls. That prevents scheduling headaches and down time. That saves money. Period.
SureFly Ignition Modules have no mechanical parts that wear and all solid-state electronics. There's no need to disassemble a SIM like a magneto every 500 hours - which eliminates the chance of introducing a maintenance related failure.
SureFly Ignition Modules deliver a more consistent spark energy with higher accuracy than traditional magnetos. Variable timing advance provides SureFly customers real fuel savings. Low power consumption and light weight (up to 2 lbs. lighter than a Bendix magneto) make SureFly Ignition Modules light on fuel and light on the wallet too.
SureFly perfectly controls timing at TDC below 400 rpm which combined with longer spark dwell and the option to use wider gapped spark plugs, makes starting a breeze, greatly minimizing wear and tear on high performance starters and electrical systems.
SureFly Ignition Modules are hand built in Granbury, Texas almost entirely from components manufactured in Texas and Michigan. Designed, engineered, created and supported by the same team that brought you Sky-Tec starters and Plane-Power alternators, our approach to SureFly shares the same commitment, experience and passion for creating and bringing sensible, affordable solutions to the piston engine aviation market.
With the low cost of the units, combined with SureFly's potential fuel savings and low maintenance/replacement costs, there is simply no better value in magneto replacements for Lycoming and Continental engines.

Intelligent Timing AdvanceFor non-turbocharged engines, SureFly controls spark advance up to 38Ί before TDC as determined by manifold pressure and RPM (engine power setting). Each engine's base timing advance is read off the data plate and set into the SureFly Ignition Module or, "SIM" at installation. The timing advance schedule is hard set at the factory, when the SIM is manufactured, to provide the highest possible combustion efficiency.Not only are points and condensers a point of failure in magneto ignitions, so are rotors and caps as they carbon track and provide alternate paths to ground as resistance builds in the system. That's why SureFly utilizes none of these antiquated technologies. SureFly components are all solid state and industrial-grade electronics.
The result is zero maintenance, zero overhauls, no rebuilds, and no maintenance costs whatsoever! Nothing to wear. Nothing to maintain. Run it to 2,400 hours of SIM operation.

PRO: SureFly Magneto bought to replace Slick 6393 & SureStart Booster was easy change for RV10 builder.
CON: After installation I find out there is 100 mil second dead spot designed into unit that when doing magneto check will cause backfire due to ACS 510-2 starter switch which most builders use. There is a fix according to SureFly GM, but not for some time into future. Also mag not compatible with GRT EIS6000 engine details for RPM display w/o using UMA MAG sensor in right Magneto. I try to get more hi-tech, yet retreat to decades ago to get RPMs ð¤

Q: Is the 8130 form included with the Surefly SIM6L free of charge?
These units come with copies of the airframe STC and engine STC in the box. If an export 8130-3 form is required, it will need to be requested at the time of order for an additional charge of $50 USD.
Q: Does this unit replace the impulse coupling/left magneto and is the price the same for a non certified/experimental unit?
The SureFly Ignition Module replaces one magneto - generally the left or impulse-coupled/starting magneto on most aircraft. They do not have an experimental option for Lycoming 6 cylinder engines, this can be used on both certified and experimental.
Q: Can both mags be replaced with SureFly units?
Not for certified aircraft.
