I've recently made several attempts on two different Nissans, a 2004 Nissan Sentra and my personal 2006 Nissan Titan to accomplish an idle relearn. All the requirements were met and I've even tried the Chrysler adaptor for laughs without any luck. I am currently a Nissan master tech with 20 years in the dealership, and decided to throw in the towel and turn my side shop into a full time deal. This unit and its capability to perform this procedure played a major role in my decision to make the purchase. 

Even at the dealer and using the Consults, idle relearn completion sometime would be a pain. These two Nissans that I have tried we're not  really out whack, but I gently cleaned the throttle chamber areas and wanted to eliminate a possibility of a mil due to this.

Thanks.
