so i bought a lund n gauge for my 2014 auto gt mainly to fix the soft transmission shifts and i know absolutly nothing about datalogging or anything else related to tuning these cars. so at this point i would just like to figure out how to read knock activity and air fuel in real time while im driving. i played around with the gauges but like i said i dont have a clue but now that i voided my warranty just want to make sure everything is safe. seems like they could include some kind of literature
