what are you guys using to mount your ecm in the factory location?

 

no one... ? the factory 91 cage and even ls1 cage won't work. has anyone relocated it to the stock location? if so then what did you do to secure it?

 

From the pictures I've seen from several swaps, alot have been mounting under the hood. I think Mr_Dude1 put his in the stock location though.

 

depends on how you route the harness. i had a custom one made with a very long pigtail so it could go in the stock location but the computer barely fits and the original cage won't work.

 

I will probably do the same thing when I swap the LT1 over to the GTA, just to clean up the engine bay, but will extend the wires myself.....this way the money I save can be used on more goodies for the car for apperance.

 

As far as I know, a custom mouting bracket has to be made.

 

I need to know as well...

 

the problem is there isn't any room, the ecm itself barely can squeeze in on an odd angle?

This is for LT1.
Check out the second pic on that thread. Thats what i'm going to do. Just use some self-tapping screws, put in on the back of the firewall. Looks too difficult to try to put it in the LT1 factory location. I think it looks cleaner too. The original wires will extend there.

 

the pic.

 

Wonder if that will work with a LS1....

 

too tight on mine to try that which is why i just had the harness extended. looks decent though, good idea.

 

thats why mines in ALMOST the factory position, and not actually vertical.... even with a longer harness, i woudlnt move mine.

 

PICS PICS PICS!

 

lol saw that coming.....

no camera right now... besides, im not taking it apart right now....if i dont have to work on this thing for another couple months, that would be great!..... just using it as a daily driver... im feelin kinda burnt out on working on cars....

 

LOL Seriously though, can you describe how you mounted it??? Horizontal and to the left of where it used to be???

 

if it was sitting on a table, flat, with the PCM connectors to your left, and you picked up the edge facing you so it was tilted between 45 and 90*, thats how mine is. when you look at it from the passenger seat.

cables go out on the center console side (aka opposite of the door side) and out the firewall hole.

it wont fit all the way up the dash like the stocker, but its higher then the bottom of the dash, so it clears the lower cover... you cant tell its not where it "belongs"

 

Awesome!

 

when speartech made the harness I had them cut it to sit on the back part of the drivers side fender.. I drilled a hole and bolted a nylon luggage strap to the fender put a neoprene pad under the pcm (aka mousepad) tightened the strap down and it works and looks fine.. no problems with water or anything else..

 

after some playing i shaved off the fins that are on the factory ecm. fits in the factory cage and installs like oem.

 

Pics? How much did you shave off? I'd say that wouldn't be a good idea, but I'm assuming the fins are there to get rid of heat, which would mainly be in the engine bay... which you are not in anymore. Sounds good, pics please!!

 

You do realize that those fins are to let the PCM cool, right? it's like a giant heatsink

 

Yeah, but probably mainly there for underhood heat in the 4th gens.

 

do i need that in the interior of the car?

 

I don't think so... maybe though.

 

well it's only been 2 weeks but the ecm doesn't get any hotter. seems to work good.

 

I put mine near where the battery use to be. Some pics are in the link.
