GRA-high became possible with any ECU on MFA+ PQ25
Posted: Sat Aug 17, 2019 4:18 pm
Hello to everyone from Russia!
Many MFA+ cluster owners using cruise control would like to see the cruse control icon on the display with stored speed. As i know every mfa+ cluster support gra high. The main issue is the data concerning gra high generates on CAN bus by the engine ECU, and it is the firmware feature, so could not be activated by long coding or eeprom modification. It is a very hard way.
But it is also another way.
Gra-high will work by external unit - the CAN emulator. That CAN emulator genarates data for gra high into the instrument cluster's CAN bus. In this case the hardest work to write the right code for emulator for correct gra high indicating of all cruise control modes: ccs on, ccs off, ccs on&active&stored_speed, ccs on&inactive&stored_speed)
In my case I used CAN filter. I bought it in Russian Internet shop ecutools.ru.
My friend provided tremendous work in developing the code for can filter, and it now works.
That is mine video.

For now it surely works with max BCM (7E0 937 090_) what about lower units it needs to check and investigate.
Friend has some thoughts to sell the codes for can filter maybe together with can filter, but it needs some time to release.
