Looking around, the same bit is used on the 2020 Escape.

There is a post in that thread about enabling the piezo sounder instead of the horn. I might try it.

There are no switches on the vehicle to turn off the double honk when you leave the vehicle running, with your key/phone in your pocket. Period.

If you can't do it with FORScan at some point, you can't turn it off.

Your research is somewhat lacking. Yes, FORScan could alter things and mess up the vehicle. Much is menu driven and many have used it on non-EV Fords, vehicles without OTA capability, to enable capabilities that the vehicle had but they didn't pay for. On my 2013 F-150, I turned on Remote Start. I enabled Hill Descent with the purchase of a $9 switch. I enabled my fog lights as DRLs. I switched my blinkers from 3 flashes to 5. When I finally buy a new battery, I can reset the BMS without going to the dealer (which is necessary for it to know that a new battery is in the vehicle).

No coding experience is needed. An understanding of the consequences of making changes is needed, as well as saving As Built, and the ability to restore it.

I had a 2018 Fusion Energi and I never touched it with FORScan. Mainly didn't know what would happen if an OTA update came for a module that I had changed. Of course Ford never made any updates OTA, and only Sync was updated, and that was via USB. Also wasn't my daily driver, so I didn't care to tweak it.
I wouldn’t say my research is lacking because you listed specific things you’ve done with FORScan, those are two separate topics. I stated what it did as a high level overview for someone who asked. And for someone who doesn’t actually know what they’re doing and on a new vehicle (that doesn’t have 8 years of people guess and checking their way thru hexadecimal bits to come up with a database of edits) and systems that are way more advanced when they were in 2013 it’s definitely possible to make a mistake that could cause some unintended side effects even if someone on the internet says it’s ok... Editing bits is absolutely coding and most code is menu driven anyway. Having at least some background in it is useful whether you think so or not. I’m not saying don’t do it, I will likely do it if I can safely do it from a cybersecurity standpoint - although sending my hardware info to a couple Russians to get a license approved seems like a really easy way for them to get everything they need to do a lot malicious things (using your hardware for bitcoin mining, using it for a local IP to create a fake social media account to generate fake news, etc). Unless something has changed in that front, which it very well could have, I will find another way.

Good news. FORScan has added support and may have even made it EASY for us to disable the double honk. I will be testing and reporting back tomorrow.

I will post the beta build then for anyone wanting to use it - but in the next realease this will be supported. My email kickstarted them to finish supporting the mach E. All I had to do was ask! They say they haven't gotten almost anyone asking for Mach E support. Maybe because I've been using FORScan since 2012 and emailing them feedback they like me more, or I'm just the first to ask!

Either way, check back tomorrow on the main thread for an update.

I don’t know much about it really but I read the wiki linked in the first post. It looks like FORScan is a home brew software made by Russians that allows editing of the firmware of the vehicle. I would be very suspect of using it… wish there was a better option that wasn’t made by Russian hackers haha. It seems to work well though and may very well be safe to use, but the origins give me pause.

It’s also basically guess and check on editing critical systems in the vehicle and could cause some major issues. Definitely not for an amateur or someone without previous code experience or at the very least a deep understanding of computer systems.
It isn't what I'd call Russian hackers. They are Russian software developers, but they're just using Fords own methods to make changes the dealer scan tool can make...for free. It isn't anything truly special or 'hacking' about it.

The good thing about as built data is in 99.9% of cases it is reversible. There are some extreme and select cases where it may not be reversible - but it is so rare I've only heard of it 1 time and it was something lighting related on an F150 in the BCM. Ford stores in the database your OEM as built and even better - save it yourself. You can download that data with FORScan and always flash it back to stock.

If it makes you feel better you can actually use the dealer scan tool to do this too...well in theory. You could in IDS, but I haven't actually tried with FDRS yet. You just have to calculate the checksum - FORScan does that for you.

I've seen the list of changeable parameters for other models. Would you guess that as many changes will be possible on the MME? Should a wiki be started cataloguing all of the confirmed changes?

Up to you but honestly no point in the wiki. If it is in the configuration it *probably* works. The only reason for the wiki is things not in the configuration. There are tons of spreadsheets for other vehicles but the MME is really unique for a lot of things. Normally they share a lot between vehicles.

I'll report back tomorrow with my findings and a link to the beta build if it works correctly :p too lazy to mess with it tonight.

Great News!

When I bought my 2015 Ford Fusion Hybrid, I tried out FORScan. There were some problems as they had not dealt with the multiple CAN networks. I emailed them some information. We went back and forth several times with beta software and debugging logs.

I'm excited for my date with a FORScan beta build tonight.

Will be great to go through car line without wondering if my FordPass is actually working, hasn't crashed, connected... No longer will I be that person who forgets to check it occasionally and double honks at everyone when my son gets out. Big day indeed.

For me, the challenges in using FORScan with the Mach-E are as follows:

1) If you change something, how does that change the interaction with other functions? With the F-150 and other models, there are thousands (tens of thousands?) of people making the same changes, and seeing the outcome. With the Mach-E, there will be tens, then hundreds. Won't be thousands for a very, very long time.

2) With the other models, the dealer can use their tools, if necessary, to put every module back to "as built". I don't have confidence that a dealer can do that with the Mach-E, especially without something "breaking", and they'd be lost as to the fix.

3) The Mach-E has A/B modules. How does FORScan handle those?

4) With OTA updates, how do they react when they check a module and see that it's different than expected, and then maybe not apply the update?

1. Generally this is known. Each number/letter in hex converts to binary. 1 = 0001 and F = 1111. Each number/letter controls up to 4 functions or settings (but doesn't have to). There are 16 combinations of on/off of various functions/settings at the same times. For example if you wanted the first and last function on you'd put a 9 in. If you then wanted to turn the third function on and keep the 4th you'd change it to a B.

Now there is a chance it does cause an issue with some other module not expecting that value...but you can see that pretty quickly by trouble codes set. Generally invalid message received codes or invalid configuration. It is SUPER easy to revert back to the old as built. I hope that answers your question. Seeing changes in real time and their impacts on other systems is pretty evident. Usually impacts on other modules is very rare depending on what you're changing. Also the module will reject the change write request if it is an invalid configuration for it.

2. First of all if you mess something up you can just put it back yourself. Super simple. If the dealer wanted to do it it is the same as any other FDRS Ford. Just run the PMI or configuration (depends on the module) on that module and it will put factory as built back in.

3. Doesn't make a difference as built isn't stored in the A/B it is stored on an EEPROM with the configuration data that is agnostic to the firmware/software. I think I understood this question correctly but let me know if I didn't.

4. They won't. There is no reason for an OTA update to read out the as built. There is a chance an OTA update will write the factory as built back over your changes after updating when it configures the module. Depends on the update. We just don't know yet because there haven't been many OTA updates.

Lastly, an interesting bit of info and why I recommend always saving your factory as built. On older vehicles (non FDRS...so even the 2020 mustang counts as an older vehicle) if you made an as built change and were internet connected the car would upload that change to Fords servers and it would get changed in their database as being correct for your car. I do not know if this happens for FDRS vehicles as FDRS logs changes to the server when they're done. Since there are supported dealer as built changes that can be made with FDRS/IDS this makes sense. It just becomes a problem if the database is changed with a ton of changes someone makes and leaves on for a while (it doesn't upload it instantly) and then wants to go back to stock.

Thank you for linking to some adapters. Does the better option access more modules? Or would the cheaper one cover everything for updates in the MachE?
They all work for everything, the more expensive ones don't require flipping a switch though to access different busses and the MX+ can do things like view live data via your phone.
