   Any particular reason you choose LSE over the P-mag?  My main concern with
the P-mag is the heat that the software would be subjected to!  Also, I
believe you used the dual LSE set up!  I was looking at just replacing one
side with LSE or Electroair set up, that is until I read about the P-mags!
 
  All:  Thank you for your replies.  I am currently investigating the reasons
for my IO-360B1B rough idle and hard starting.  Electronic ignition is but one
of the remedies I am looking at.

Scott,

 

1. P-Mag had no history, no experience and users that they could reference (except for one aerobatic guy that had experience with one E-Mag).  There was no hi compression experience.

2. They are big and I have no room.

3. There is no timing data (like the LASAR). BUT, I do like the configuration switches on the units.

4. Regardless of how irritating Klaus is, the LSE system is proven although not simple.  Klaus races!

5.  If I want, I could adjust the timing of the LSE system.

 

The heat should not affect ROMs.  However, you are correct to be concerned.  E-Mags have been around a while yet there is not enough info about them.  Arnie has had no problem with the P-Mags so far on his Lancair 360.

 

I am not impressed by "moderates" or one sided electronic ignitions.  While they are better than two mags (EIs, not moderates), I will never be convinced that flame fronts started at totally different times is an effective ignition system.

 

If you have reached a point where the mags need to be overhauled, you should seriously look at the P-Mags - especially if you just want to fly rather than screw around like I do.

 

Now, to your problem.

 

EIs won't fix poorly running engines but can be a good replacement for bad mags.  Are you sure the idle mixture is proper?  Are your mags/points worn out? Ignition leads in good shape?  Plugs properly gapped and clean?  All plugs good?  .......
