I had it in my car for like an hour and took it out, it was too confusing for me, i got it to work on learning mode but it was too confusing..... Im looking to get $400 or best offer for it, and it comes with the 60 page instruction manual, and the Optional External Signal Wiring Harness for analog and data logging, plus it comes with the USB cord to link and tune the E-Manage with the E-01.... If anyone is interested please let me know, you can pm me or post......
