As I was taking apart the intake I noticed that the computr is in the box (wow what the heck GM) If I replace that with a cone filter will the PCM have problems overheating, seeing as it sits in the air box? I live in cali where summer temps get to 95+ often D:
I honestly don't think so, my 99 Suburban with a 454 gets hotter than you can imagine under the hood, FAR more than my 00 Park Ave does and the PCM has never overheated and there is zero airflow over it.
I think you will be fine.
Honestly at work, my old group did PCM's for brand F, C, H and a some other stuff and we designed around -40C to +125C OPERATIONAL. That is 257F. I don't think you will ever get the PCM itself to those temps.

You'll be fine. Been utilizing a FWI set-up for years in GA. For the past 10-15 days it's broke 100*. Here's another thing, for example a lot of the S-10's and Blazer's have the PCM sitting in a tray on top of the Coolant resevoir. That same tray that the truck utilizes are available for purchase in many FWI kits as it also will support our PCM's. Hope this helps.
In reality, the underhood temps from 70F to 120F ambient is likely only a couple degrees different. It is heated by the radiator that is pushing 195 degree air into the engine compartment all the time.
You should be underhood of my 454 on a hot day.... the radiant heat and the heat being blown on you from the 9 blade (yes 9) clutch fan is mind boggling (and cooking!)
Honestly a 80 degree day here and 107F down in Arkansas really felt the same to me....

One would also be surprised at just how much heat is generated in the engine compartment from the condenser of a vehicle utilizing A/C. Big difference. Thomas as far as 80* in Illinois versus the hot-humid south you gotta be the bionic man. That's the first time I ever heard that. When I lived in CO I used to think it was hilarious when the hottest days were below 90* with no humidity. Now I just think it's funny when every one comes down here for the Masters Tournament and can't believe how hot it is not realizing that April's nothing compared to July/August.
there ya go
