Lynn,

I've gone with dual Light Speed Laser III ignitions on my Super ES. I'm mounting them in the cabin side of the firewall on the copilot side, above the horizontal shelf. One mounts vertically to the firewall, and the second is above the first on standoffs. I had to plumb the manifold pressure into the cabin for the sensor anyway so this was not a concern. The wires from the crank sensors I'm running through the firewall on a multipin connector, and I mounted 6 BNC bulkhead feedthru connectors in the firewall. These are for the connection to the coils which is made using RG-400 coaxial cables.

I do have dual batteries and alternators, without which I would not go dual electronic ignition. The big drawback compared to a magneto is the need for DC power to run them. I have split the systems between the two buses.

I second the concerns expressed on the need to install the system properly. I had the ignition system installed by Performance Engines when they built the engine, and it was tested and timed before the engine was delivered.
