: Airbox Computer?

04-12-06, 09:25 PM
Ok so I just got to looking at my new 01' DTS. I started looking around for things to play with, you know, mod's. When I pulled the airbox apart and found a computer in there I quickly put the screws back in and closed the hood.

I can only assume that this is the ECM and they located it there for cooling?

Anyone know anything about this?

It's the PCM and yes, it is in the intake air stream for cooling.

For some reason that seems crazy to me. So if I wanted to alter the airbox for better / cooler / larger airflow what are my options. I hear people talk about drilling holes in the bottom but since the thing sits on the inner fender that doesn't seem logical to me.

Volant makes an intake for the late model Devilles. I'm not sure how the PCM is cooled with that installed though.

This subject has been beat to death. If you do a little research, you'll find that you won't gain anything.
