Safe Temperature Limit for Tuning
 

Well I've had my Gryphon now for about 2 weeks and it's still in the box while I wait for warmer air to arrive here in NH. In the booklet it says not to tune at extreme temps, 20 to ???. I only noticed the cold side since that's what I'm dealing with.

What is a real safe temperature for me to wait for so I can try this new toy out? Our weather here in NH is cold and snowing right now. (sick of winter now....) with a week of cold temps during the day and single digits at night.

Bill, what do you recommend? I'm hoping I can install this before my custom tunes arrive. But if it's not safe (I'm an engineer so I believe in being conservative when necessary), I'm not going to install...

Time to go plow some snow...

Thanks
Henry

you can program your truck as long as you have your pcm warmed up to temp.........just let the truck fully warm up!
It's much colder here where I live and I reflash my truck quite often :thumbs up yellow:

Chris is correct. Get the PCM warm and keep the Gryphon in the house where it's warm before you try to upload a tune. Make sure the electrical load on your truck is minimal (no headlights, heater fan, radio, etc.,) and you should be fine.

Warm everything up and you're fine.
