Mk3 ST to Mk3.5 Instrument soft update

Recommended Posts

Hey guys,

 

Hope you are all well.

I’m looking in to possibly flashing the software on my mk3 st instrument cluster to the mk3.5ST software...

 

I’ve done a bit of reading and this can be done, there are a few compatibility issues but nothing major and nothing to put me off. I noticed when I swapped from sync 1 to sync 2 that the ICP colour and splash boot screen changed and looked different once I uploaded the config of a later year ST with the same specs.

 

Anyone attempted this or could offer some insight? Really fancy the digital speedo read out and the added trip options. Also noticed hidden in the settings menu you on the 3.5 you get more options.

I experimented a lot with MK3/MK3.5 instrument clusters and the different MK3/MK3.5 software versions.

The MK3 and MK3.5 Level 3 (full color) instrument clusters are technically 100% identical. The only differences are the hardware and software version numbers. Because of the different hardware version number it is not possible to update the MK3 instrument cluster to MK3.5 software using the Ford IDS or FDRS diagnostic systems. 

The only way to load the correct MK3.5 software files (the MK3.5 software consists of 3 different software files) onto an MK3 instrument cluster is by selecting the correct software files manually. There are only a few diagnostic systems that are capable to do this. The best / most reliable ways to do this are currently the Russian UCDS diagnostic system or the (highly experimental) Forscan Beta Test version 2.4.0 in combination with a Ford VCM2 diagnostic interface.

It is not recommended to update the instrument cluster software using the FoCCCus software in combination with an ELM327 interface. Updating the software of a Level 3 instrument cluster using the FoCCCus software and a high quality ELM327 interface takes a very long time. At the maximum supported Baudrate of 500.000 Kbps the update procedure takes approximately between 12 and 16 Hours. I found this method only to be successful when performed on the bench outside the vehicle.


When installing MK3.5 instrument cluster software onto an MK3 instrument cluster the parking sensors sound will no longer work. On vehicles with Active Park Assist both the visual and sound will no longer work during automatic parking. This can only be solved by upgrading to the MK3.5 PAM module (in case of Active Park Assist this also requires 2 additional parking sensors). Next to this the interior/instrument backlight dimming function will no longer work correctly if the instrument cluster is not configured correctly.

Also be aware that most of the additional MK3.5 instrument cluster settings will not work on a Focus MK3. 
 

After a few weeks I decided to go back to the latest version of the MK3 instrument cluster software. I discovered that I barely used the digital speedometer and dual trip computer. It was definitely not worth the loss of  parking sensors sound and the loss of both the visual and sound of the Active Park Assist system.

Sounds like more hassle than it’s actually worth.
It’s a shame on the mk3’s you can’t swap out the full cluster for essentially an LCD screen. You can do this on the mustangs, it looks absolutely amazing and it’s plug and play too! Absolute game changer.
