Ei for IO540

[Bill.Peyton]

I just realized that my new 540 does not come with an impulse mag and requires the slick start module for $650. I am now contemplating replacing one mag with an EI. The question is, what are the choices? I know of light speed , but I really like th simplicity of the P mag, but it appers a 6 cylinder model does not exist on their web site. Are their any other mature solutions out there for a 540?

Really???

What did you get?

Straight from vans/LYCOMING. It has a retard mag and requires the slick start module.

You may consider an Electroair system ... I still have an early generation ~1994 vintage system that works great. Only thing I've ever replaced is the mag pickup 6 years ago. They have come a long ways since then and seem to have a great system still. I have a Slick impulse mag on the left and the Electroair for the "right" mag.

Emag has a model for the O/IO-540 they introduced at S&F. Brad says it should be in production in 3 to 4 months and if you order now you will save over $300 each.

Getting ready to pull the trigger.....probably go with one with a mag as b/u.

What was the price they offered?

I had an Electro air that lasted about 250 hours on my 540. First the pickup or more accurately the flexible arm that holds the pick up allowed the pickup to contact the timing wheel. After that was replaced some temperature sensitive components in the coil plate gave up. The new ones allow you to mount these parts in the cockpitt side while the coils stay on the engine side. However for the 540 the clamp on timing wheel under the ring gear is still the way it's done.


In the end I opted for a second mag and put a slick start on the LH mag. It starts like it has an EI hot or cold.

You really sure??

I can look up the details of our mags, but that does not sound right to me.

By the way no slick start modules in any of the RV's I have anything to do with.

I fear you may be on a hiding to nothing!

By the way.....we have lost count of the numbers of starts in 600 hours.

Bill,

Take a look at the G3i. That's what I've installed. I like it because the mags are still the backup if the ei fails. Larry Vetterman did a great write up of his tests with the G3i on his web site. Thomas will also talk as long as you need to answer any questions you may have.

The Lycoming "as-built" document lists two mags installed on my engine P/N 66LP-OSCNN (6350)and P/N 66LR37-SCNN (6393). The latter being a retard mag. I don't understand why they don't ship with an impulse coupled mag.

Bob, thanks for the input.
