Trucks Due for inspection this month. Have the Gryphon CS with custom tunes. What, if anything, do I need to do before taking it in? Just return to stock and remove it?

No I would not return to stock (you will throw a code). Just remove it, and leave it programmed.



Edit: State Inspection

Oh really? I always thought it wasn't "safe" to run the custom tune without the programmer connected. Learn something new everyday.

Thanks for the link.

Rob, and everyone else - Once you have loaded ANY tune into your PCM, you can disconnect the Gryphon, CS/CTS or whatever programmer you own, and put it in a safety deposit box if you wish. It is only actually needed for programming. Once that process is complete, it simply acts as a passive "monitor", telling you things about your engine and transmission that you would otherwise not know. In other words, it becomes a "display device".

In my case, when my vehicle inspection was due, I first used the device to check for any codes. There were none. Then leaving my custom 87 octane daily driver tune installed, I unplugged the unit at the OBDII port and drove to the inspection station. I didn't even bother to remove it from the dashboard, since the vehicle was never going to be out of my sight. (I did tuck the cable up behind the dash so it wouldn't get in the technician's way when he plugged his probe into my OBDII socket). If the technician noticed the unit, he didn't say anything - my guess is, he didn't know what it was.

My truck passed the inspection without incident. And, I simply plugged it back in when I got home.
