Vibration isolating Motronic ECU mount(ing)?

[famoroso]

Over the years, I've availed myself of a number of 911chips.com / Steve Wong's services: off the shelf chips, two custom dyno tunes, 24 to 28 PIN socket upgrade, ECU functionality test, ECU rebuilds, etc.

Everytime I R&R a Motronic ECU, I think about some of the things that I've read here on Pelican about the box / circuit boards being mounted horizontally and solder joints cracking due to that and hundreds of thousands of miles / decades of vibrations.

Both of my current 911s have more "sports purpose" levels of NVH than they left the factory with 36 and 34 years ago... stiffer suspensions, stiffer tire sidewalls, firmer engine and transmission mounts, spring centered clutch discs, JWest and WEVO shift couplers, etc., etc.

Anyway, in addition to wishing for a set of longer knurled aluminum fasteners that would allow me to remove & reinstall ECUs without using tools, I've considered isolating the mounting of the ECU box itself via something like o-rings on the mounting studs (both between the floor and the box and between the box and the mounting hardware) or adding some low durometer foam tape to the bottom of the ECU's mounting flanges, etc.

I'd love to hear people's thoughts. Is this a valid thought process? Am I overthinking it (which is fun / ok too)? Both?

I suppose a similar inquiry can be made regarding the DME relay, but I run solid state units, so I don't lose sleep over those, or at least... Not much sleep. ;-)
