I don't know it just me or something. I used lot of live data. Now it so much lagging
take 10 second to react. O2 sensor, maf, rpm. And so on...

why don't u try 2001 Xterra 3.3l , see everything work. only thing work for me is Engine. No airbag ,or transmission ..

If I can go back to day 1 , i will take it. In my case i didn't backup the data.
