So if you don't mind rolling your own it can be done.


Unfortunately I think it's unlikely that I could build my own system for less than $350, which is how much I have to pay the dealer. A smarter person who already has the tools and know-how might do it for cheaper...but then they would need a monthly cellular plan on top of that...if you could get a plan for $10 per month it won't be long before you have paid more than $350.

So I think I'm talking myself into paying for the dealer upgrade here...unless a4bry4 comes back with some guidance on getting it for free!

Ostensibly you need an Arduino that can process CANbus input to track the SoC and push that out to a cheap LTE module.

If you just want to know when it's finished you can skip the CANbus part and just monitor the current draw or something else like the battery contactor.

You could also measure the battery voltage directly - rather than decoding the report from the car - and process that through ADC to avoid the need for CANBus hardware as well.

If you have to use CANBus, you'd use a board like the one the CHAdeMO mod uses http://store.evtv.me/proddetail.php?prod=EVTVDue2 which sold for ~$100. Their newer and more expensive one has dual CAN transceivers which you would not need for this application (but could be VERY useful if so inclined)

But since you are just looking to monitor a single bus, you could get away with a much less expensive CANBus shield (https://store-usa.arduino.cc/products/can-bus-shield-v2) on a cheap Arduino. The cell modems would be the most expensive part at around $100 +/- $20 but with the obscene number of stupidly cheap cell phones, I would have to guess that sending SMS through a bargain basement phone over bluetooth or USB would be preferable.

So depending on what exactly you want to do, it's $200 for an Arduino with integrated CANBus and the cheaper LTE.

If you don't need CANBus integrated in one unit, an Uno and a CANBus shield are about $60 together and another 80-120 for the LTE

If you skip can CANBus monitoring altogether it's $30 for an Uno and $80-120 for the LTE modem or whatever you want to spend on a pre-paid phone. Either way, the trick is to do it as a pre-paid data plan with some cheap block of text messages to pass data back and forth. If it required a $10 a month ongoing expense there's nothing that will beat the real one. But if you can buy 1000 texts for $10 you'd have something that goes on a LONG time depending on how chatty you want it.

May not be worth it to you specifically but anyone else in the same boat, that may or may not have the option for the upgrade, should know.

If you did tie into the CANBus and had a reliable data input you could actually program the board to send any number of CANBus messages to the car. If you wanted to get really cheeky with the Dual CAN board and it allowed you to specify what the device ID was - you could imitate any other module on the CAN Bus and send messages to do anything it supported - remote start, climate control changes, etc. Read and set stuff that isn't possible even with the stock TCU hardware.

Oh, your tire light warning is on? I'll text you the PSI values reported by all the TPS sensors. Oh, you want to shut off the battery cooling but leave it plugged in to charge? Cool.

I got the upgrade done today at the dealer. As noted had to shift to the FordPass app. It’s not as user friendly as the myford mobile, but it works. Had to pay for the modem kit, but labor was free.

Thanks for sharing your experience at the dealer. About the Fordpass app, do I have to subscribe to that? Am I going to have any costs here besides a one time hardware upgrade?

If I am going to have to subscribe to Fordpass then it makes more sense to put the effort into something like Anti_Climax's Arduino solution, which actually sounds pretty cool. Probably outside of my ability, but very cool.

Mine is a 2018 so I didn’t have to pay to use the FordPass app. I had used the app previously with my Escape PHEV and my 2018 Fusion sport. I don’t think Ford has started any way to pay for the app yet.

Looks like I can still get the kit if I like, but they will not be enabling the option for my 2012 to be programmed by the dealership.

So, short of me buying it and somehow figuring out how to program it myself, it looks like I'm out of luck.

So, I've been corresponding with the gentleman that re-programmed and sold me the Sync 3 APIM. He's been working on a few TCUs relating to this Customer Satisfaction Program, though not for a Focus electric so far.

With what he knows of the process, he's pretty sure that Ford "not permitting" my model year in the software won't actually prevent the process from being done on an older vehicle - it would just mean it has to be done in a more manual fashion that a dealer likely won't do.

That all said, he'd like to do some testing and would like to find a "junk" VIN he can put in the system. If anyone has the VIN for a <2016 Focus Electric they know to be dead/junked/etc, can you please DM it to me? I've asked 'J in TX' but figured I'd put out a wider call. It might also be worthwhile to have him look up a newer Focus electric VIN to see what he can get for a car that is actually "allowed". Same conditions would otherwise apply - one you know is dead/junked/etc

With my Ford contact noting he can help me though the process of getting the TCU, this could mean an unsupported but otherwise functional migration to LTE may be possible for all us pre-2016 owners - and I'd love to see that happen.

So, he basically has a bench top SIM that can be loaded with different configs. He set it up to SIM a portion of the 2013 Focus EV and paired up an LTE TCU, and it showed up in Ford Pass, though it showed less than he normally sees for something like a C-Max, but that could be a side effect of it simulating a limited number of components.

Based on that, I'll be buying and trying it once I hear back from my Ford contact.
