Hello guys forgive me about my weak English

Just asking about something that happened while reading Nissan ECU
"Can't read the ECU with the Editor and even normal check with the scanner"
Imported Nissan's from USA are Readable, but the ones are sold Here in Dubai, United Arab Emirates , I can't read them at all.

Is there any lock on these ECU's? NO Engine Temp, spark etc... even can't clear DTC or read.

Thanks
