Ross, I have the Lycoming twin sheave flywheel and your magnets installed for the dual systems. Aerosport drilled the holes, but seemed to be just fine. Not sure I would have tried to drill the holes myself, though.

Good.

I recall discussing this with the guys at Aero Sport but didn't hear how that went. Could you email me a photo? There appears there may be 2 different types.

Ross,

What's the lead time look like right now on a dual-ECU injection package for a four-cylinder Lycoming? I'm thinking I might go ahead and buy the system before building the engine up so I can integrate it all on there as I go. (and, this way I'll have covers for the magneto and fuel pump holes...)

Our backlog to build an EM-5 is about 4-5 working days at this time.

Default RV-14 Fuel Filter

We're doing a number of RV-14 systems these days and the question has come up several times about using the Van's supplied Andair filter as the SDS pump pre-filter.

Yes, that's fine and we can discount our pre-filter from the kit price if you want to go that route.

Default Injector Boss Mounting, Fuel Hoses, Plug Wires

We've made a slight procedural change when assembling the thread-in injector mounts on Lycoming engines.

Previously we specified using VERY small amounts of red Locktite for the NPT lower body into the cylinder and on the SS 8/32 cap screws holding the top body to the lower ring. If too much was used, it's extremely difficult to ever remove these parts.

We now specify a high temp blue 246 Locktite instead where the quantity is far less important.

The installation manuals have been updated with this change.

We also recommend you use the -3 braided fuel hoses and fittings we supply with the kit. These are lighter and have less fuel volume than -4 which some folks have fitted instead. We always want to keep the mass as low as possible here.

Finally, we've made a new recommendation to ohms check your finished MSD plug wires. These should read 50 ohms per foot of length. Also check these values at each annual.

If you want to change hardware from what is supplied with the kit, it's a good idea to check with us first. We may have some very good reasons for doing or not doing something which might not be obvious to you. Reliability of the fleet is often dependent on following what's been proven in hundreds of thousands of flight hours. Making changes to that recipe can sometimes have unknown consequences.

Default Lead Times

A couple guys called this morning about lead times on the EM-5 systems. At this time of year, we are generally at 7-14 days depending on the ebb and flow of orders received.

Default Magnet Position Setting

In the last couple months we've had a few people call, being unsure of the procedure on setting the magnet offset values for the crank sensor which we call Magnet Position. This applies to CPI, CPI-2 and EM-5.

The most important aspect, which is often not remembered, is that you must know what timing mark you'll use on the flywheel to verify timing and set the Magnet Position value. Most Lycoming flywheels are marked on the back side with 0, 10 and 25 degree BTDC scribes.

If you choose to check timing at 10 BTDC for example, be sure to set 500, 750, 1000 and 1100 rpm timing at 10 BTDC and idle the engine at 750-1000 rpm. If these are set to anything else, it's easy to get confused.

On systems using the dual Hall sensor pickup, we find the settings should be 88 for primary and 97 for backup. Note that starting in late Spring of 2019, all dual Hall sensor cables are marked green for Primary and red for Backup so these can't be easily mixed up. CPI-2s have green and red paint dots on the ECU connector faces denoting Primary and Backup.

Once Magnet Position is verified, you can set RPM ignition timing to whatever values you wish. This is a one-time calibration.

On dual pickup systems (twin cables), you should not have to check timing with a timing light when using the values above, as long as you get the correct cables plugged into the correct ECU. If you mix these up, both ECUs will deliver the wrong timing for the engine.

On single sensor systems (one cable), the Magnet Position value should be around 92.

We recommend on all these systems that you keep the 500 RPM timing value at no more than 10 degrees as this value is used during cranking. The ECUs bring in 15 degrees of retard below 300 rpm so this should result in true cranking timing at about 5 degrees ATDC to avoid kickbacks.

Default Western Canada SDS Installation

We've added a new partner in Canada to do SDS installations in Alberta, Saskatchewan and BC. Harry Jaeger from Caddis Aviation offers mobile service to your plane and can also help with most other maintenance and avionics installation tasks. Great guy, 30 years experience on all types of aircraft. You can find links at the bottom of our Aircraft Page.

We have another recommended shop at Springbank Airport as well who has done multiple SDS installations if you're local.
