Do you have AlfaOBD, you can test fire them with it. How hot do you let it get before shutting it down.

Which elm327 are you using? I've found some of the really cheap ones ($10 or so) aren't great on compatibility. A good one I've found is the BAFX Products OBD2 reader. I've used the bluetooth one (about $23) with my phone and Torque Pro, has worked on my 2006 300C SRT8, 2006 Silverado SS, and several 2018-2022 Ford F450 work trucks. I see they now have a Wifi version available for $28, might be the ticket for use with your laptop.
I'd check with the AlfaOBD people first though and see why you're having connectivity issues and maybe ask them specifically about the BAFX adapter before buying.
Which reminds me, tried finding mine the other day and it's disappeared, which sucks, because I rarely lose stuff. I had pulled it out of the toolbox to loan to a friend but he went ahead and put his truck in the shop first so I didn't get it to him.. now it's gone.
