Gryphon not operating under ambient temp of 40 deg.

[f150ian]

Greetings all!

'02 F150 4.6L 4x4 Reg. Cab, Serial 2410

I've been having an issue lately where the Gryphon WILL NOT connect to the PCM under an ambient temperature of 40 degrees or so. What's weird is, when the engine is up to temp and the cab is up to temp (er-comfortable ~75 deg), the programmer will connect no problem.

This leads me to believe there's an problem with the Gryphon's hardware when it gets cold.

The truck runs the same on stock or 87 tow. It is currently stock as I'm trying to resolve a cyl 2 misfire on top of this.

Anyone have any ideas?

Thanks in advance,
