So I have been running a Level 2 (87 tow) for a few months now without any issues. Today things got weird... I went to de-ice the truck as usual. Get scrapper from back seat and then lean in and start the truck. It turned over a little longer than usual, sounded weak, then just stopped. WTH?!? Radio was reset, Gryphon flashed my HEX code, it was just weird. So I reset it to stock, truck started fine. Reset back to level 2 and started the truck. It started but sounded a little off. The gauges (all of them, mostly the speedo though) were "freaking out" and vibrating a lot at their zero spot and then they all instantly snapped to attention and went where they should be. I let it run while I scrapped and listened for anything odd. Reset to stock. Weird gauge thing was gone. Set back to level 2 and got the needles to freak out again (but it started). Set back to stock and everything was fine. Drove to work because I didn't have any more time to mess with it. I don't know of any specific reason why I wouldn't be able to run Level 2. I don't have any mods other than the Roush Off Road (dual rear exit). The only other oddity I have noticed lately is it sounds like one of the pulleys is squeaking or the belt is making noise. I replaced the belt a few months ago since it was making a terrible noise and slipping a lot. It has been problem free otherwise. Ideas? I'd like to keep running level two but if the cold is too much then I will just suffer through the winter at stock. I will say I did not have problems a few days ago at 9*F, for whatever that is worth.
It's because it was cold. I had the same problem in Fairbanks, if you bring the programmer in to warm up, it should work again. I can't explain why it doesn't work, but that was my experience.
That makes sense. The whole thing wigged out and just kind of failed. I'll leave it on level 0 for now. It seems strange that the programmer is still in the loop at that point. In my previous vehicle I had a piggy back on the ECU that read in the values and "changed" them to work with the stock programming. With that you had to turn the key to the on position and wait a few seconds before starting to let the unit boot. Guess I'll just have to suffer the winter out then. Unless there is a way around it. I am not sure that bringing the gryphon inside every time is going to work. For what it is worth, it seemed to be okay down to about 9 degrees. Guess 5 degress is just too much lol. Could be. Which side is the alternator on? I am not 100% positive, but it seems that the sound is coming from the drivers side. I wouldn't be surprised though. Guess it would be a good excuse to go to a bigger alternator
Try setting it to level 2 and then disconnecting the Gryphon, it will stay programmed and hopefully won't be all sketchy.
Like cowboy said,when it gets to cold it just goes haywire.I had the same problem last winter and i tried a few things which worked for me.Let the truck warm up for atleast ten minutes before driving(i tried that and it works for me)Up load the level two setting(87Tow),take your tuner out and it will continue to run that setting on your truck.
Hrm. Could just be that is still the problem and it just sounds like it is coming from the left side. I'll have it checked out next oil change. So far it has been intermittent. I'll have to try that. I like having the gauges on it though. I'll try setting it to Level 2 and I have to leave the tuner unplugged all winter so be it. Not sure how old it is. I bought the truck used Nov 09. I will have a look at it and see if I can find a date or anything. Everything looked spotless (which is why I was OK paying as much as I did). I have just shy of 93k miles on it.
Good point about the battery, I just replaced mine and haven't had any issues with starting it cold. Though I let it warm up a while before going anywhere too (its -15 this morning)
