FoCCCus Central ECU Config Edit – ELM327 – Focus MK3
FoCCCus Central ECU Config Edit has been developed to provide the same features of the ELMConfig program, but for the Ford Focus MK3 (2011 – 2016) owners.
FoCCCus Central ECU Config is a fairly new program to the internet, and is still currently being developed, but it is still in a good condition to use, to enable auto door locking, turn off passenger seatbelt warning chime, disable your day time running lights, and is also useful if you retro fit anything like a tow bar, where you can enable the tow bar functions yourself without visiting Ford.
The opportunities are endless with the new FoCCCus Central ECU Config program, and best news is, its free. All you need to do is get your hands on a ELM372, and modify it, or send me an email and I may have some modified ELM’s already made.
Modifying ELM327 USB
Like the previous guide I posted on the ELMConfig post, you will need to modify an ELM327 USB OBDII reader. To complete this task, you will need the following:
- 1x USB ELM327
- 1x SMTS (Sub Mini Toggle Switch) – Miniature Toggle Switch ON/ON Dual 3A
- 1x Soldering Iron & Solder
- Heat Srink
- Philips Head Screwdriver
- 5mm Drill Bit
- Wire Snips
- Wire Strippers
First you will need to remove the sticker on the front of the device to reveal the 4 screw holes underneath.
Using your Philips Head screwdriver, remove all 4 screws holding the plastic casing together
Now break the two halves of the ELM casing into two to reveal the board and cables which make the internal parts of the ELM, and remove the USB lead, and you can also remove the OBD port to allow for some space for the next steps
Take your switch, and align the switch up on the inside of the plastic casing, as we will need to drill a hole into the plastic casing for the new hi/lo can switch to be seated (remember to use the opposite side where the capacitor is located). Use something to make a mark on the outside of the plastic. As you can see my switch is 9mm wide, taking into account the width of the plastic on the inside, I drilled a 5mm hole 8mm inwards. Once measured, take out the motherboard from the plastic casing, and put the two halves back together and tighten the screws. We will now proceed to drill a hole 8mm inwards and exactly centre between the two splits where the two halves meet.
Now undo the two halves again, and place the motherboard back into the casing, and then test fit your switch into the hole we just created.
Now the wiring starts, we will be wiring the switch using the following diagram:
There will currently be wires going from the ELM connector into pins 14 and 6 on the OBD plug. If you trace these back to the ELM side of the plug, they should be as displayed in red and green in the diagram above. Double check yours is wired the same, if not, you can just trace the wires back. Cut wire 6 and 14 in half. Wire 14 from the ELM connector will be soldered directly to the middle pin of the switch, and wire 6 will be soldered to the other centre pin.
FoCCCus Central ECU Config Edit Program
Now you need to download the FoCCCus Central ECU Config Edit program. This is
- FoCCCus Central ECU Config V0.5.1 (Local Download) – Released 10th March 2014
Also available from the FoCCCus developers website: http://ford.xtlt.ru
Once you open the FoCCCus Central ECU Config program, you are shown the window above. This is where you should plug your modified ELM into your PC. The program should then establish a COM port which you will select from the drop down menu named “serial port”. Once selected, press the open button the the FoCCCus Central ECU Config program to open a connection with your vehicle.
You will then be shown the page above. This will identify what options have been set on your vehicle, and what options are currently disabled. Some options may be disabled as they may not currently be fitted to your car.
On the bottom of the window, click the “Read from BCM” button, and you’ll notice all the settings on this page change to identify your current ECU settings. It is a good idea at this point to “save to file” your current settings, as we can then use this to write back to the car in case of an error.
Below is the fill list of options currently available to change on the Ford Focus MK3 with the FoCCCus Central ECU Config program.
