Good evening. My 2006 F350 6.0 wintered for 4 months like every year. At the first start yesterday, my Edge CTS2 showed me this error message below. I have had the Edge installed since 2018, so far it has always worked reliably. I drive a Gearhead tow tune and don't want to update the CTS2 until I get the pcm back to the stock version.

I paid in 2018 $US 1375.- to GH to get this answer now (asking for help):

“I hate to say we no longer have support for the edge CTS2. We are primarily on SCT now”

How do I get my PCM back to the stock tune now?

Can anyone recommend a competent dealer for Edge devices who might be able to help me?
Unfortunately, I have not received an answer directly from Edge products.

Thank you.
