As far as not needing a standalone and Ecuteck can do it all. That is a heck NO! If the tuner can't see all the data needed and blows your chit up. Then, nothing is said and the car is given back to you broke. Yeah, you need a standalone to add all the additional sensors needed to properly tune the car. If you aren't logging it, you are guessing and asking for trouble. My bad for trusting that tuner. That's not happening again.
