Tuning MED 17

Post by Nieznany0 »

Anti tuning remapping Since mid 2009 we have seen the introduction of protected
Bosch EDC17 & MED17 using an Infineon Tricore processor, and people are often told
that these new Tricore ECUs cannot be remapped as the vehicle has “Tuning protection”
or the ECU itself is “Locked”, this simply is not true! There is no such thing as a
“Locked” or “Anti-tuning” software, however, there are many inexperienced or
poorly equipped tuners that do not understand these ECUs and rather than
admit they have no knowledge on these latest systems, they simply say it is not possible.


Safe and reliable solution for programing these ECUs,
this is via a Bootloader technique as pictured above, which involves the removal of the ECU
from the vehicle and making a direct connection allowing the reading and
writing of the Tricore processor. This is the only safe way to remap any EDC17 or
MED17 ECU, because please remember, these ECUs were introduced firstly without
any protection (pre 2009), which would allow OBD flashing, but during normal servicing or
warranty repairs, the dealers do have the ability to update the old non protected software
with the new “Anti-tuning” versions, where this is the case, any attempts to reprogram
the ECU via the OBD (On Board Diagnostics) can cause fatal damage to the ECU.
