Ei for IO540

[Auburntsts]

Bill,
You don't need the SlickStart Module for your 6393 retard breaker mag in order for it to start your engine. It can help if the mag is having problems, but is not required. The choice to switch to an impulse coupled mag is more along the lines of do you want a mechanical system (the impulse coupler) or the battery (the retard breaker) to give you the extra "spark" to start the engine? My Barrett IO-540 came with the 6393 as well and I'm sticking with it.

Here's a good read on all things magneto:

Thanks Todd, Based on a couple of reports I have read, over time as the points get dirty etc. the engine will become harder to start and the additional spark is needed for a quick start. I was not going to install the module and see how it worked without it. I also was going to fly phase 1 with just the mags and not an EI system.

600 hours, never a start problem, except when some dumbo left a master on

David,
Do you ever run LOP with the dual mags?

Bill,
I have before (my RV-10 isn't flying yet) and everyone else who's flying standard certifed aircraft LOP certainly are. In fact, John Deakins, author of the Pelican's Perch series of articles over on AVWEB suggests that in lieu of the standard run-up mag check, that you conduct and in-flight, high-power, LOP mag check to really determine the health of the ignition system.

But don't get me wrong--I'm a fan of EI, I'm just pointing out the art of the possible. I plan to add EI myself at some point, but it's at the bottom of my wish list and I simply don't have the cash right now.

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

Hmmm.....

I have been in touch with Brad for the last 18 months or so and the P200 has been coming "soon" most of that time - still waiting I've had my engine shipped without mags in anticipation.

Don't get me wrong - if the Pmag-4 is anything to go by it will be a great product but they are at least a year behind schedule.

By the way, what was the projected price?

Barrett Perf was working on an electronic ign for the 540------you might give them a call and see what the status is.

I have tried repeatedly to contact Barrett about their Ignition (Zeus). After the initial posting they made, they have been MIA/Absolutely silent on the offering. So I am suspecting they have run into some major issues moving forward. Just my assumption.

Who knows, maybe they are just secretive. But when they asked for engines to dyno with their product, I offered up my brand new YIO-540 straight from Vans. Still no word/info from them.

I have same mags as you but with the slick start and I run LOP all the time below 65% power. Injectors are not balanced so I get a fuel flow spread of 1.5 gph as well as my first to peak having to go to 40F LOP before last reaches peak. Runs smooth here but I am sure it can do better.

I am planning on calling Don on balancing injectors later this summer. My only question is we spend time and money balancing fuel flow but what if your problem is air flow related? You may be running leaner on one due to increased air flow vs decreased fuel flow. Sorry for thread drift. I am terrible for that Bill.

I kind of thought balancing the injectors did that. We speak in terms of FF, but by changing injector sizes in an attempt to equalize FF across all of the cylinders in fact balancing the air fuel mixture which takes into account variations in the induction system, at least to some degree?
