Yes, some good news!
After several weeks of work, I have created a prototype OBDII module that memorizes the last STOP-START OFF setting and restores it when you turn on the ignition on your 2016 or 2017 3.6 liter Grand Cherokee.
I expect to start shipping them in October or November.
There is a sign-up sheet on my website so I can gauge the size of the initial production run.
It also memorizes and restores the state of the SPORT button!
Here is the sign-up website: www.smartstopstart.com
. There is no cost or obligation to sign up for notification of availability.
There is a video demo
there also (sorry the audio is slightly out of sync, I need to redo it).
