My colour touch is working great in my 1996 4.0 fuel injected Cherokee.
Usually accurate now to within 1 litre per fill, and i have a 120L tank.
Love the Distance to Empty feature.
Glen, did the older versions have built in Bluetooth?
Wouldn't mind checking it out the app.
The link you provided doesnt take you to the site.
Perhaps this one will..
