Is there still any way to reprogram PCM module for cruise control myself or is only way to do it to bring my car to Ford mechanic who does have Ford IDS and is willing to use it? I got quote of EUR 150 for reprogramming the module which seems a bit high price for me (unless they guarantee results for that price and fix everything if something goes wrong).

Anyone (civil-zz, Psyence, ...) willing to share required knowledge, algorithms etc. so we could create Android application capable of re-configuring AS-BUILT data just like Windows applications do? It's pretty inconvenient to carry laptop to my car while I could just do everything via ELM327 bluetooth dongle and my Android phone? Personally I am capable of Android programming should special timings. etc not be needed for serial communications.

Mk2 focus CC buttons are not integrated to the steering wheel. They are connected to the wheel using screws and yes, they can be bough separately. However, steering wheel originally without CC buttons are NOT compatible with buttons. It seems that our Russian friends from FFClub have fitted buttons to non-buttoned wheel, but they have cut some plastic etc. New buttons does cost just as much than used wheel with CC buttons, so there's probably no point getting just the buttons (ie. I paid 70 EUR for leather steering wheel with CC buttons )...

Can you modify a bluetooth elm like you can the USB one?

Yeah, I have modified Dealextreme's bluetooth ELM327 dongle and it's working flawlessly. Inside it's just like USB version but instead of USB chip it just does have bluetooth chip.

Hello!
For CC activation you have to perform changes in three modules - GEM, HEC (IC) and PCM. ELMConfig is able to work only with GEM and HEC. I can tell you why. There are some differences btw CONFIGURATION and REPROGRAMMING. configuration is mean that you only change some storage parameters in module nonvolatile memory. And reprogramming is mean that you totally erase all controller microprogram with it's calibration and parameters, and then write back a new one with new parameters which you want to change. So, all modules in Ford Focus can be configured excluding PCM, it need a reprogram to change a work parameters (it' s exactly so, it was performed by module developers for reasons unknown to me). Configuration is relatively simple procedure, but reprogramming requires special skills and i don't have them yet. IDS can do both procedures and for end user there is no differences, but for third-party developer it's a huge one.

Thanks civil-zz, your explanation makes sense! So it seems that activating cruise control does require visit to garage having Ford IDS or similar hardware and software. Too bad as my local Ford mechanic would charge enormous money for the job (EUR 160)
