Okay so I recently purchased a December 5 2014 build date ST1 and I am unable to get FoCCCus to work. The vbf files I need aren't on Ford's website and the newest version of FoCCCus is lacking them. Do I just need to wait or is there another option?

Try connecting with FORScan. How does that connect? Forscan has an iphone app and a pc app. Use the pc one.

Have you tried connecting to the built in wireless webpage of the MX Wifi? if you have what kinds of options are there?

I found a forum this after doing a quick google search, http://www.obdlink.com/setup-category/mxwf/ where it says cnnection type using obdwiz try setting the option as RS232. That should allow you to assosciate a com port with the wifi connection.

I haven't tried forscan but I'll give it a try shortly. The Web configuration page of the MX Wifi only has simple settings such as changing ssid a d password so there isn't anything there for me.

As for the connection type in OBDWiz, that drop down is just for connecting the program itself to the MX Wifi. If I select RS232 it will no longer search for the MX through the wifi connection but rather through an RS232 connection, and since there is nothing plugged in in that way, the program couldn't connect.

I'll spend more time today searching for someone else who has run into the same problem. If there's anyone on here who has gotten an MX Wifi to work with the Focccus app please share your wizardry!

Either way, thanks so much for your quick help jdub!

You dont need vbf files..i could have sworn i editted the vbf files thing out of the 1st post months ago.

The only way you might need them is if something is different about your ipc or bcm that focccus doesnt recognize..interesting... can you send me your VIN?

I'm a little behind. Last time I messed with this was back in 2013 when I had an SE.

FoCCCus was telling me it could not find the correct vbf file or something like that.

FORscan works fine.

Rs232 is a serial communication port standard hence the words "com port." As far as i know this is the only way to get focccus to work which is through serial communication.

Well now it works. I don't know why but it is working perfect now.

Weirdly enough but somehow Amazon now gets the post office to deliver on Sundays. This was just delivered.

Its a low profile OBD2 Y adapter. I should be able to leave my MX and my AP3 plugged in at the same time. Im not sure if they will interfere with each other yet.

They've been doing it here a lot too. I talked to the mailman once before and he said he doesn't mind it since he gets paid overtime.

We have Prime, my wife wants to know if its related to that. We dont mind the delivery we just want to understand how or why. This isnt my first Sunday delivery either, i just didnt question it at the time.

Yeah he said something about amazon prime. We don't have it but we still had a package come in.

Keep us posted if the y splitter works with an obd link MX and accessport. Based on reviews on amazon there may be conflicts

 

[Now534]

I would suspect that there may be a conflict since the AP is already going to be connected to the Canbus adding another device may not even connect.

As long as they're not both actively running at the same time it should be OK, otherwise its likely that there would be issues. The way UDS and OBD diagnostics works it would cause problems having two test tools trying to talk to the same ECU at the same time. Responses to one tool would be confused for responses to another. Data would likely get mixed up or never come in at all.

If the tools are just monitoring the communication then any number of tools could monitor the same traffic without issue. However, generally those devices are polling for information through diagnostics so they probably won't work right.

Ok, so both units cant be plugged in at the same time. Both the accessport cable and the MX can be plugged in but if you connect the AP it will never connect to the car. A message pops up saying something about trying to connect except it never does. If i exit out of Torque Pro then the AP connects and logs fine. If I then go back into Torque the AP will drop the connection.

On a side note, the low profile adapter is great. Because of its small size the white car obd2 connector can stay locked into its holder and the Y adapter seats fully and the access door still closes.

One thing i hate though atleast with the 13 model is the dang obd2 port is upside down. It makes things hard to read especially things like the MX whose 4 lights on the front all mean different things. I wonder if the car mount can be modified to make the white connector lock in right side up.

You can fix the upside down part. Depress the clips and rotate around and reclip.

That doesnt work for me...it wont reclip into place like that. The shape of the cutout is different which makes my plug only fit one way. Ive tried many many times to make it go the other way and it wont even go into the hole.

That's odd I've done it on mine.

@Bugasu - I acquired my secret key recently but what can be done with it? Ive read about something called mode 27 that is some kind of security mechanism built into our cars. Can you shed some light on the subject?

 

[Bugasu]

Mode 0x27 is called Security Access.
Basically an ECU is supposed to lock certain features away as secured functions.

These include flashing, reading the ROM file, adjusting certain stored parameters, etc.
Typically you enter a diagnostic session using Mode 0x10 on a module, and afterwards perform the security challenge using Mode 0x27.
Then you can go on to use Mode 0x34 & Mode 0x35 to download/upload data, or whatever else needs secured access.

Typically the requests are challenge/response based, so I'm curios as to which secret key you have.

There is also a Checksum for ECU files you may flash for example, which if it isn't correct, the car will not start. (Part of the Bosch MED17 anti-tamper functionality!)
Originally, people thought we'd end up like VW/Audi having to send our ECUs in to be bare-metal programmed because of this, but @COBB and SCT have obviously figured out how to circumvent or generate proper checksums so they can modify ECU files.

I doubt they're willing to share such secrets as there was some R&D cost and it probably wouldn't make business sense. Other modules like the BCM, IPC, etc. as far as I'm aware don't have such anti-tamper protection, but to be honest, I don't know or not. I can flash files that already exist obviously, but those have the checksums already built in correctly. Calculating new ones is not something I've tried to do, and the people who can do it don't typically share the info on how to do it, either because they work with Ford directly and are NDA'd, or because they spent all the time figuring it out and use that info to make money (rightfully so! It's an investment!).

 

[jdub1981]

I did a metric ton of googling yesterday and found out I already have the needed hardware for CAN sniffing. Focccus has the ability to brute force the secret key(s). I have 2 different keys so far. Ive seen that some people use the keys for nefarious deeds and others do it just for fun or to make a little money. I want to do it because these are things ive always wanted to learn about. Im no hacker but I do like to tinker. I know it takes a long time to figure it all out, but Im into the ST for the long haul so I got time. Here are some things id like to figure out:
