How warm does the LS PCM get?

[beeman]

I have room for the engine PCM (and throttle control unit) behind the passenger seat in the cockpit, and I would prefer to put it there to make some more room in the engine bay. Does anyone know if they put off much heat to where it would warm the cockpit significantly?
Looking at ls forums, some will mount them under the dash, but others say they are hot to the touch when running.
Thanks!

I have my crate ECU in engine bay, right side behind fuel tank like most, is this different unit?

Yeah, that is the typical location. I was going to move it to the cabin so I could shuffle some things around in the engine compartment. Maybe I will just mount it where the manual tells us to.

I dont think the unit gets hot at all.

I dont think the unit gets hot at all.

Yeah that's what I would have thought, but some of the LS forums have posts about the thing getting untouchable.
