Cummins insite

How do I go about getting insite for my laptop to bring on the road with me? Is it free? One time cost to buy? I would like to have it in advance of any possible codes with my isx. I am running Windows 7 Home Premium. Also need to know where to buy the hardware to connect it to the truck. It is a 2016 389 with 2015 isx. The idea is to keep ahead of any maintenance issues that may arise with the emissions systems with help from Rawze's videos. One time cost? I would also like to be able to change some of the speed limiter/rewards settings and see if the upper droop/lower droop may actually save some fuel. In other words I would like to have more access to inside the ecm than what the bully dog hdgt provides.
Thanks

 

Pulling reefer usually 75 to 80k most of the time from Ontario and western usa/Canada averaging 5.5 and governed to 65. Ontario to nj and in between average in low 6s.

 

After watching a whole lot of rawze's videos I have renewed faith. So far (knock on wood) it has not been problematic and eventually I had to upgrade my old truck. Plus I got a very good price on a 389 the first owner could not meet the payments and the finance company didn't want to hold it forever. So much more comfortable for otr driving.

 

Yep that's pretty much my findings.
I have a bunk heater and haven't had to idle overnight yet. I bought it in August and was running Ontario to nj/pa and with the side sliding window and front windows down a few inches and a fan it makes for comfortable enough sleeping. I know idling is the fastest way to screw up the emissions stuff. It does cost more in payments than my old fl was in repairs, but it should have much better resale at its approximate half life when the payments end. All in all I love driving it. Finally get a little respect lol
