unplugging Gryphon once PCM is tuned?

[Chris74]

Hey folks: I just returned my truck to stock and unplugged Gryphon because the truck is going to dealer tomorrow for a Ford Reflash.

But for future reference........is there any reason I can't load one of my tunes and unplug Gryphon once PCM is programmed with the tune (and truck would still function properly on loaded tune)?
I was just thinking that if it's done stock why can't it be unplugged with any tune?
Was thinking I could unplug it for the winter.....or atleast during the bitter cold weather to save the drain in the battery while programmer is in sleep mode. But I would still be driving my truck on performance tune.

Yes indeed you can do that. I removed my Gryphon when I drove my truck about 150 miles into Mexico out of fear it would get somehow "liberated". The unit simply acts as a monitor once the PCM is programmed on any level and has no effect on the truck at all.

Before I bought a Battery Tender, I unplugged the Gryphon too, since my truck does a lot of sitting in the garage.

Thanks Jack!
.....that's exactly what I thought........I just don't know why it never dawned on me to do that. I wouldn't have needed a boost in the airport parking lot!
For some reason it just never occurred to me that I could unplug but still be on my performance tune.

Does it pull that much juice in sleep mode??

I measured it and Bill confirmed my measurement. It uses about 50 milliamps (or 0.05 amps) as "keep-alive" current. Now, that's not much by itself, but my truck also pulls 0.05 amps when it's turned off once everything is powered down according to my measurements.

So, if you add the two, you have a steady 0.1 amp drain on the battery when the truck is parked. In 24 hours, you've sucked 2.4 amps out of the battery.

Interstate says a battery is dead when it has lost 50 amps. That happens in just under 21 days at a steady 2.4 amp/day drain.

If you open a door, use the keyless entry system, etc., you turn on lights that really suck power out of the battery for a while until everything is allowed to power down again. Once a battery gets low, its voltage is reduced which causes the amp drain to increase too since all these "gadgets" need a specific amount of "keep alive" power (which is volts x amps). I also know that a low battery causes the Gryphon's screen to stay lit, even when off, and that pulls MUCH more power too.

Bottom line, if your truck is going to be parked a long time, disconnect the Gryphon or use a Battery Tender, like I do.

Hope this all makes sense.

Cool. Thanx for the info. My PIAA 525's are wired straight to the battery so they
Can be used whenever. So the led's on the switch are always on.
