Awesome. Just called them and waiting for a recovery. Anyone have this issue?

**Phuck Phace** · 05-23-2013, 04:48 PM

Yes, unhooked battery, waited 10 minutes, reloaded just fine.

**Midnight11** · 05-23-2013, 04:53 PM

Ditto

Dirty D recently had this problem.

**Grandpa** · 05-23-2013, 05:30 PM

Nope. I let Sean tune it, put the SCT back in the package and haven't touched it since. It won't get used again until Kevin tunes it. I've seen too many stories about them bricking and rather not tempt fate. lol

Battery trick fixed it. Thanks guys.

**DirtyD** · 05-23-2013, 08:34 PM

Dale and David got me through the issue. Glad it fixed you too

**JDMLOL** · 05-30-2013, 03:01 PM

Just wondering. Do you have to unplug the battery before every time you return it to stock?

**DirtyD** · 05-30-2013, 03:06 PM

No. Just do not try and tune or return the car to stock unless the car has been sitting and the charging system has cooled down. The heat makes it go into fail safe.

It's what they call the "keep alive memory" (kam). If simply unhooking the battery doesn't do the trick you can leave the car overnight. Switch the headlamps on the next morning for 10 minutes (with engine off). Switch the lights back off. Then reconnect the batter. All about discharging the KAM in the event it loads to 99% and fails etc.

So basically its deleting the half loaded tune so you can start over?

In a nutshell; the car stores a certain amount of voltage to the PCM. It periodically spikes the PCM which closes the doorway on the SCT HH.

Yup. That's why you get charging system messages when you tune upload fails. The voltage spike is pretty much the failsafe mode

Could this be what happened to my F150. I went out to start it a couple weeks ago, everything lite up like it was going to start but it wouldn't do anything. I disconnected the battery for awhile, hooked back up, still nothing. I plugged in the SCT knowing I needed to put the stock tune back on and the handheld device said "unrecognized vehicle" or something like that. Long story short, I had to have it towed, the local Ford house said I had a dead PCM, 8 days later, $900 later, (out of warranty), I have my truck back. Of course ford said it was either the programmer that caused it to fail or they also saw "mouse tracks" on the engine. I can laugh about it now, but at the time is wasn't funny. I live in the country so the mouse tracks is no surprise, but really..... that's grasping in my opinion.
Just curious what every one thinks. I have not tried to put a tune back on the truck. I'm going to send my programmer back to SCT and let them check it out.

Damn, that sucks, let us know what SCT says about the programmer
