I have two race engines (12As) with electronic distributors. Both leading
and
trailing are triggered by the leading pickup. There is a MSD 6AL for each
coil. Both leading and trailing fire at 27 degrees. from idle to 9,800
RPM. No
ignition problems of any kind.

I fly a Zenair Zenith 200 powered by a 1986 13B equipped with a Mazda 1985
electronic distributor. I do not use the vacuum advance devices. I have
wired and switched leading and trailing separately, thinking that if one
circuit failed in flight I could fly on with the other circuit. With my
timing light, I adjust ignition timing to about 20-25 degrees BTDC leading
and about 15-20 BTDC trailing.
I never thought of using the leading igniter to control both leading and
trailing circuits, but now that you mention it, I am tempted to make it so,
if it will make a marked power improvement in the 5000 to 6000 rpm range.
Please advise.
Yvon.
