To those who have LASAR on their 320/360 -- especially Bill
Harrelson and Scott Krueger. As I recall you put the controller on the
firewall. Do you remember how long the Low Voltage Control Harness
(between the mag pigtails and controller) is?
I'm planning on LASAR on a Superior XP-360. Any suggestions on
configuring this system would be much appreciated.

I mounted my controller on the right side of the engine mount using adele clamps. The circuit breaker is mounted alongside. The "harness" is ordered by a code which represents the length of the lead to the left and right mag. Go to the unison igniton product website and read the 10 (?) part configuration and installation manual (see below). Call the Lasar rep in FL, thay are very helpful. I believe that now one can order directly from Unison.
I would suggest installing a power switch on your panel so that comparisons betwixt Lasar and mag ops can be made on the same flight. Also, the engine cannot be started without the computer engaged. The only modification is to remove the "short the non impulse coupled mag at start" connection. The power cable (power, indicator light, etc) is quite long (6 feet?). I connected the manifold pressure line to cylinder 1 rather than tee it off the mainfold pressure sensor tap on cylinder 4. Generally, Unison says that you will not need the cylinder head temperature sense logic - they never saw it needed on any experimental, just certain Far 23 certified airplanes that could not stand a 20-30 degree higher cyl head temp in climb.
