Hello so I found someone parting out his car so He selling a Ecutek tuned ecu and his car it’s same mycar model and 6 speed manual and he said I can just plug it and play do do you think if I do that it will works and is anything bad will happened to my car!
thank you !!

 

If it doesn't have NATS deleted it won't work.
if it does then yes however NATS delete will trigger a red security light.. if you can live with that then it will work.

 

How much are they selling it for? You could probably get yours tuned by someone with those crappy tunes for a similar price and not have to worry about a second hand ECU.
