Hi I have this proble in the microtech software wen I going to modify the parameter I try to modification put in 0 and I can't modify

 

Is your ECU locked from your tuner?

If not, you could try switching it to matrix mode and making your change there.

Oh, I've seen versions of the laptop software where the keys are reversed. As in, down is up and up is down. Try the other key.

 

hi thanks for your response , as when the ECU is locked ?

and I test with several keys and all the same, when I positioned in the box I want change and pressed the M since then the parameter is set to " 0 " and since I can not change it does not move from 0
