Hi, new here and to tuning. Just finished my LS swap on my 1986 Buick Regal and tuning the 4l60e. Worked great!

My question involves using the vcm scanner and it's gauge display. I would like to add an odometer in the gauge display as I no longer have a cable driven speedo. I know I can purchase a box that can feed the existing speedo but I am interested in replacing all that with a digital dash. I am NOT looking to change the milage on my swap, in fact I'm hoping I can use a formula to add the actual mileage of the car into the digital dash. Hope I am explaining this correctly... Any thoughts?

Regards,
Mike
