Went to my dealer today to have the original map flashed back on, can't be done to my horror!!!!
If you have the latest Vauxhall software in your ECU, whether it be standard or altered my EDS/AMD/Mantzel/V-Max, you can't flash the basic programme back on.
TIS states, "Latest version of the software already installed, re-programming not possible"
So basically I am stuck with what I have and can't run standard software unless I buy a new ECU or Vauxhall issue a newer version of the software, which is doubtfull because the Zafira 3378 code has been current for 12 months.
May be worth bearing this in mind, so if you have a standard ECU and is on the latest software, once it is mapped, you can't reverse it!!!!
