I saw a brand new Lightspeed fail this weekend .. most probably due to heat under the cowl since it eventually re-set. The aircraft had mags on one side ... so no big deal. However, wouldn't you think that the current generation of electronic ignitions would take into account that under the cowl on an airplane is HOT and make some sort of consideration? It's my understanding that the vast majority of these ignitions controllers are installed on the fire-wall? Anyone else had any ideas, recommendations here? I think these are great electronic ignition systems and am looking to install a pair on an aircraft .. but it was an old fashioned MAG that got us back to the airport!

I believe the Klaus recommends to put the controller on the cold side of the firewall (inside the cabin). Was this recommendation followed by the builder?

No the unit was on the engine side of the firewall, where I've mostly seen them. Room is the primary issue here. Thanks for the info. I'm wondering about blast tubes directed on it?

That is not such a great location, ...even if it had blast tubes.
Computers are like brains, keep them cool so they can think!
I'd mount them inside the cool cabin, instead in the hot engine compartment.

Heat might not be the only enemy here.;
If the best location (in the cabin behind firewall) is not an option, the brain box could be shrouded inside a .020 aluminium cool box with a blast air tube feeding it cool air.
The possibility of the introduction of humidity and whatnot being introduced via the blast tube must be considered.
Keep in mind that the brain box was designed to be inside the cabin out of the ravages of weather and under cowl contaminates.
It might not be completely weather and environment proof such as most ignition cdi modules etc. that are found under the hoods of automobiles.
Take care,

I don't know about current production, but Klaus' ignitions always used
to have a port for forced air cooling to be fed with an avionics fan or
similar. Before I hogged the port on ours out to 5/8" and got a good fan
on it, it ran very warm and it did need a new power transformer after
about 700 hrs. He uses a different transformer now which is supposedly
less susceptible to heat damage, but all the same, I would put it on the
cabin side of the firewall and fan cool it if I were you.

Hi all
I'm a '6A builder in Corvallis, Oregon. Long time builder, first
time poster. I happened to install my LSE module this week.
Here is the relevant text from the current edition LSE manual on
installation of the Plasma II and III modules:
"
2.4 IGNITION MODULE AND IGNITION COILS
The PLASMA CDI module should be mounted in a clean and dry place on the cold
side of the firewall. If space limitations require mounting on the engine
side of the firewall, a protective metal cover should be used to protect the
module from water/engine cleaning materials and heat. In this situation,
the module should be oriented such that the connectors are to the sides of
the plane. Air must be allowed to flow between the bottom of the module
and the mounting surface. "

Mine is mounted on the inside (cold side) just like Dan Checkoway's, I have not had a problem 85 hrs so far. I don't think Dan has had any problems.
The directions do say something about not putting it in the engine compartment.

Its really not a problem to install on the cold side of the firewall.
Yes, you have to cut the supplied cable, but its a simple solder job on
a radio shack 9 pin plug is all it takes to fix. You only need to drill
a very small hole through the firewall.
