See no mention of locking and unlocking the device in the instructions provided with the tunes. Not saying I didn't screw up by not putting my old truck back to stock, just trying to figure out my options now. I only posted last night because I was in a desperate situation and had limited time to try and resolve it before resorting to putting my stock intake system back in place. I'm already in contact with Troyer about this. They said I should have just been able to unlock it like I tried with the liveload, but that isn't working.... I will update once we resolve it.

I had no problems at all when I bought the device and tunes for my old truck. It couldn't have gone easier at that time...

Okay, it has to be sent to SCT to be unlocked... that's another $150 spot. Anyone want an AF1? Not sure I am even gonna mess with it, thrown too much money into this already.... my own damn fault...

 

Hi.

Sorry to hear about your issues.

I got these specific instructions from TP with my new tune order (I did the same as you - moved my XCal2 from an old truck to the new one:

"You will need to check the FW version on your tuner and update it to version 1.14 from the Sctflash website (support/downloads and drivers) and use liveload to unlock the tuner. There are tutorials for using liveload if you have not done this before - also on the website. I am assuming of course that you returned the original vehicle back to it’s stock program before you sold it….. ".

Assuredly, all customers get the same communications. I had zero issues, and I'm just a dumb old guy ;-)).

Did you try to completely erase the device?

Check to see if your X2's firmware is at v1.11 or 1.14.

Update with Live Update to 1.14 ( not 1.15) if it's not.

Then check to ensure you have the very latest rev of LiveLoad3 from SCT's site.

Try the (full) Erase function in LiveLoad - nothing to lose at this point, and it may save you some bucks.

Then try to upload up your new tunes into slots 1 thru 3, provided you got past the above.

Important thing is, don't get discouraged - chit happens. You'll want to keep that AF1 if at all possible.

Good luck & let us know.

Cheers
Bubba

 

Yea I hear you, I was thinking earlier about checking the version of my tuner and updating if needed.

19-1 is dangerous and lean enough to cause problems -especailly at wot- wher safe numbers are around 12.5-13.1-obviously that run of the f150 at 19-1 under wot wasn't enought to turn on the cel- good job ford-think about what you typed-

 

hopefully chester takes this as constructive criticism and learns from it-

 

Well,

I really killed the device now. I tried to load the same firmware revision and in the middle of it I pulled the usb out, now it won't even come on. I thought I could still get power back to it to reflash.. was attempting to somehow erase its memory about being locked. It was a last ditch effort, I have a voice message in to SCT to send it back and pay that dang $150 to unlock it. :-(

 

Well, Troyer Performance told me to call SCT directly to request an RMA yesterday, but when I called SCT they told me Troyer Performance had to put the request in. It appears Troyer Performance is closed due to bad weather today. So much for getting this thing back before the weekend I guess....

So, you're tellin me that you can't buy an intake without having a custom tune to go with it?!!

Well the AF1 website doesn't say anything about needing custom tuning. Seems kinda stupid to sell a product that will break your truck. Or to sell a product that requires you to buy something else, but they neglect to say it. Are you saying that the product is that bad? What a piece of crap. If you have to have custom tuning, then you have to take the intake off EVERY time you return the truck back to stock! Can't take the truck to the dealer to get the oil changed without returning the vehicle to stock, and do you have to take the intake off every time?!!

I have said numerous times that if I got something wrong, I would be quick to change it. Did I Not? I did not use wikipedia to get ANY info on these engines. I had a few reference papers from ford a long time ago, that outlined the function of our computers, and it's been a long time since I read them. So I may have a few details wrong. But here you are, telling me that this intake is going to break your truck, in spite of the fact that they sell them every day to people that don't have custom tuning. And in spite of the fact that they don't say anything about having to have custom tuning. Now, I don't know everything about these trucks, or their tuning, but I do have a basic understanding of how they compensate for changes in the intake. And I know that if the engine was running lean, it would light a CEL. Just as it does when you get a vacuum leak. Vacuum leaks make an engine run lean. Lean enough for the PCM to decide it's dangerous, and does a vacuum leak blow your engine up? NO!!

My guide has nothing to do with intakes.

If you find something wrong with my guide, post it here, and I'll fix it. If you don't see anything wrong with it, SHUT UP!


Give me some facts, and I'll shut up. I've been wrong before, and I'll admit it when I hear some explanaton of why I am wrong. And he-said, she-said blah blah doesn't count as anything to me.

I have always respected your comments. And from your previous post, you sound like you know a lot about intakes. Would you please explain how an aftermarket intake will make your truck run lean? Why wouldn't a new air filter do the same? Why can't the truck detect the higher airflow at a given throttle position? Why is the truck unable to make adjustments to the fuel map to compensate? Why doesn't it detect a lean condition when running closed loop? Why wouldn't the truck set a CEL for a lean condition, if a lean condition was in effect? And mostly, how is it, that nobody has ever mentioned that they broke their truck from running lean because of an air intake? These are questions that I need answering. Coming here and makeing fun of me doesn't answer anybody's questions.

 

So, you're saying that ford doesn't know what fuel ration their trucks are supposed to run with?

How many people do you know broke their truck with an air intake?

 

The MAF sensor in the intake is specifically calibrated for a cross sectional surface area of the stock intake tube. When you change the size and or shape of the cross section, this sensor may no longer be calibrated to accurately measure the ‘true’ amount of air the engine is receiving. The MAF sensor is basically a heated wire positioned in the air stream whose resistance will change in relationship to mass air flowing past it. Changing the velocity of the air changes the amount of heat removed from this sensor’s wire. A smaller diameter tube will increase air velocity where as a larger diameter tube decreases velocity.

If you place the MAF sensor inside a larger tube, less heat will be removed from the wire because of lower velocity. This means the MAF sensor is measuring less air than their really is. The ECU doesn’t know this and therefore it won’t be able to compensate the mixture by enriching it with more fuel, thus your lean condition. After the mixture is combusted, the O2 sensor will report the mixture info to the ECU. If the combusted mixture is too lean, the ECU will flag a lean condition and illuminate your check engine light.

 

Understandable, except that they were saying that it was running lean and still not setting a CEL. Also, why would they use the stock MAF sensor in a larger diameter tube? I was not aware that they did this. But again, it doesn't make sense.... That actually seems rather foolish...

 

While doing R&D on the Air Force 1 on my truck ( stock tuning) I went as lean as 17-1 without setting off a CEL. However, it did go into the "limp" mode several different times during this time, which was a little over 1500 miles. Every time it went into "limp" it was running in closed loop..So if you think it can't happen you are dead wrong....

Chester, you really need to spend more time trying to understand what can and has happened on these boards instead of trying to disprove something you do not believe in....thats why some here treat you like they do....

 

Ok, so you ran so lean it went into limp mode. That thing is a piece of junk.

Why do they use the stock MAF, Marc? They ought to know that will cause problems. Why don't they come with one that is calibrated for the extra diameter, or have a narrow piece there to compensate?

One thing I don't understand.... The computer goes into limp mode AFTER it throws a code. So how did yours go limping without getting a CEL? That's not the order of progression inside the computer...

 

you just don't listen......I don't know why , I just know it does and I accept that.....
