I believe it is only "vulnerable" if you remove it from the stock intake box. And this is debatable as well...

 

Remove the ECU cover in the air box, you'll see it still gets weathered. Everything appears okay though.

 

An open exposed ECU outside the stock air box is only 15* hotter. I don't know if that's enough to cause an issue, but I am a skeptic that aftermarket intake has caused the ECU failure. Done plenty of ECU replacements on Volvo that have never been modified.

I would not relocate purely due to the amount of wiring necessary. I will be working on what I call the ice box for the ECU. Stay tuned, projected for this summer.

that sounds glorious.

 

Really would just be for piece of mind, I took a temp reading of an ECU in the stock air box today that read at 130* which was what mine read at laying on top of the transmission... Prior I had a substantial temp difference but was a pretty cold day. This shows that when a car is hot off the freeway and heat soaked they read very closely the same.

Also, have to consider I have numerous modifications to reduce under hood heat temp so could very well be the differences I am seeing vs. someone else that doesnt.

 

want me to take the reading of mine after i drive 75 miles on sat? i have mine in the BSR heatshield .. btw what would you have in mind for this so called ice box lmao
