I have read it succes (back up)
I have write the mod file back it says succes
But the car doesn’t start and the fan is on

Then I write my orgi file back and it’s good no problem like before all good

I have a stage 1 + egr off
Friend have make it for me the modfile

Readwrite with openport tactrix software flasher by alex

Is it maybe the tool is not good?
Why can I write back my orgi file without any problem?

Is it maybe the modfile?

Get your ori ok, modify some simple map, save and write. If car ok then it's your egr-off method. If not ok then it's tune program or checksum.
