For the monochrome gyphons, yes.

For the CS and CTS gryphons, not without being instructed by Bill.

I will be using my new PC from now on, so i will have to install Pegasus on that. Will I need to update the computer name on my open ticket?

thanks

That'll work. Just make sure that you update pegasus when you install it onto the new computer. I think the link on the website is an older version.
And yes, update the computer name and any other relevant information on the open ticket.

Well today I had a new problem. I was leaving work and my truck went into the Fail safe mode. I stopped on the side of the road, turned it off and started back up and everything has been fine since.

Not sure if this can be linked with the rough running problems that I have been having.

Were you able to check for codes?

I ran the Pegasus update. returned message Gryphon updated successfully.
Firmware Version: v3.10.1063 .Calibration Version: v2.04.1012 .

Went to plug it into my truck, and as soon as the gryphon is plugged in it says 'external memory needs to be reflashed - call tech support '.

argh. ticket #136.

Is there no way to reflash with the current software? I guess the pegasus client detects that the flash is 'current' and there is no option to reapply. Should be easy enough if there was that option.

edit: doesn't look like it. I guess if I had custom tunes (I don't) I could reinitiate that download and it would fix itself. But as it is, it looks like PHP will have to throw the canned tunes in the 'custom' bin so it can be reflashed.

same kinda issue as this, except mine didn't have a comm timeout. it all seemed to work fine. I can still see my serial #. http://forum.gopowerhungry.com/close...t-timeout.html

I did not check codes when it happened because I totally forgot that the Gryphon could do that... LOL!! But I just checked now and no codes show up.

Engine fail safe popped up on the information screen. I was only pulling out of the parking lot at work so I immediately stopped and turned the truck off. I am not exactly sure what happens in fail safe mode. It just doesn't sound like a good thing. Everything seems fine now. Nothing out of the ordinary happened when the message popped up.

Update to my post #123, I installed pegasus on a different PC, and was able to reflash the unit with the same firmware/calibration this same. hopefully when I plug it into my truck the 'memory' error is no longer there.

but then we are still back to the hesitation/missing issue

Wow...what is that exactly? What happens when a truck goes into fail safe mode?

"Failsafe" is actually designed to get you home if your truck engine overheats. (It's also known as "limp home mode"). Basically, the PCM shuts down spark and fuel to half of the cylinders so that the engine can run cooler.

As I said, it's supposed to be triggered by overheating, but it seems that the PCM can apply this strategy any old time - possibly caused by a false sensor signal. If you're really paying attention, you'll see the temperature gauge peg on full hot as it goes into failsafe mode. The PCM is actually moving the temp gauge there, since it is not actually telling you what the coolant temperature is (there's no sensors for that value - it's inferred by the PCM from the Cylinder Head Temperature).

The fact that an engine shutdown and restart often clears this condition is almost a sure sign (to me) that some sensor is malfunctioning.

Got the fail safe error again today. I immediately checked for codes and this this is what I got. And again I turned her off and started back up and all was good. Same I was leaving work and as soon as I pulled out of the parking lot bang, fail safe.

P061B Internal Control Module Torque Calculation Performance

Anyone have any idea what this is?

After reading a bit in the forum, I see that this code may be related to the tune. Everything that I have seen says canned tunes, but I am running a custom 87 perf tune. Please help!
