Small change in startup
 

Running my Gryphon on a tune by Bill. I have an 06 f150 xlt 4.6. When I use my aftermarket autostart the last couple of times the screen showing the HEX file appears but goes away when I hit enter. Now it does not do that when I start with my key.

?????
What was it like before the custom tune when you were running canned tunes?

I may be misunderstanding something, since I don't have a remote start system.

You should not normally see the hex code on startup. It only happens when you first install your Gryphon, or, after you have disconnected the Gryphon or the battery - which kills the "keep alive" memory in the unit.

It sounds to me like your Gryphon is operating normally.

The way I understand it the hex code shows up every time the remote start is used. Right?
Doesn't show up when key is used? Right?


Lars

This is correct. I never unplug the Gryphon and I have not removed the battery. Now an update. The HEX code apears on auto start sometimes and sometime the screen appears showing the four display boxes but no data in them. If I go to the menu and then exit out the data appears.

OK, I misunderstood. (It's very easy to confuse me). :o

All this strange behavior has to be related to your start system, but, you're the first person I've ever heard comment on it. I wonder if it has to do with the way "run" power is delivered to the OBDII port?

I sure don't have an answer. Perhaps the Mad Doctor will see this and have some thoughts.

Here's my assessment of the situation, and correct me if I'm wrong.

I'm going on the assumption that the programmer will reboot during remote start on the first startup of the day (after sitting overnight) or when leaving work (after sitting all day). The overnight scenario fits my logical thinking better and I'd say that's probably when it happens most often. Again, correct me if I'm wrong.

Reboots have generally occurred on startup after sitting overnight because the battery drains down enough to drop the voltage below 8-9 volts while cranking. The engine will still start but the programmer reboots. After this initial incident, there is no further issue the rest of the day because of the minimal amount of battery drain between starts.

I don't believe the issue is related to the remote start, but more of a coincidence that it happens because you use the remote start the same time every day versus when you do a key start.

In a nutshell though, the battery is most likely starting to fail. Historically, when the programmer reboots overnight or during cranking it is time for a new one. The one in our Expedition started this little display of temper about 20 day before the battery puked. New battery... No more problem. In fact, we've seen a number of threads where the poster had indicated their truck/battery was about 36 to 40 months old when they started seeing this problem, which ironically was how old our battery was when it died.

Hope this helps.

Great solution. I have noticed my interior lights dim a little when my power steps go up or down. Im still showing good volts on the battery from the Gryphon but I gues thats because its running. I need to get a more powerful one anyway withh all the electrical addons. Any suggestions on a great battery.



Again thanks guys.:D

Great thread! You're right you are seeing normal voltage with the engine running. That's alternator voltage. If you have a multimeter, measure the voltage at the battery with the engine off after it has "sat" for about 8 hours. If the battery is weak, the voltage will probably be under 12.4 volts.

I keep recommending Costco's 100 month/36 month free replacement batteries. They have higher capacity than the OEM battery and are reasonably priced.

Well the battery was toast I was cranking at about 12 volts if that make sense. No Costco's areound here. I went with the Duralast Gold. I have a lot of aftermarket stuff hooked up so I figured a 3 year free replacement wouldn.t hurt.
