Can not read a 03 4.0 wrangler

[Scottyb6.0]

Rookie question I?m guessing but I can?read a 2003 Wrangler Ecm.
I get a Unsupported Interface. I?m using the latest version of editor and hp tuners interface.
I?ve tried two of my hp tuner interfaces. Same issue. I?m still using the hardwired usb interface.
Any help would be great

Have you tried the Beta version? That is what i have to use for my caliber to read correctly.

You need an MPVI2 or MPVI2+, and an internet connection, to read JTEC computers. You cannot read it with your old MPVI. Look on the supported vehicles list to see which vehicles are supported. The ones which require a newer device have a blue coloured "(2)" beside the model.
