Curious what this is proving. I know we use to place hard drives in a freezer before boot up on voicemail systems as a last ditch effort to get a system up. Freezing would allow the platter to spin up and load. Ecm is solid state so just curious.Pull the ECM off and stick it in the oven at 175°. Plug it back in and fire it up without wasting any time. Leave it off the block so it does not transfer any heat out of the ECM. Long shot but free.
