Hey guys noob here. I'm having a hard time finding tools and info on tuning my 98 vw tdi ahu. I have edcsuite but im kind of lost on a few things. one is the file types and what they are for for example ols files kp files. im familiar with .bins and xdfs as most of my experience is with tunerpro but these are all new programs to me. I'm hoping maybe someone could point me in the right direction maybe even to a guide on tuning tdis as this is my first one. any help is much appreciated thanks.
