I live in Boise Idaho and have a 02 Jetta TDI I just had to do a motor swap due to a broken timing belt. I grew up building race cars for circle track this is the first diesel, as well a the first modern European car I have ever had. I love my car it is the most repair friendly car I have ever had. So long story longer I had a friend come by with vag com to help with the injector timing and a few other mods. After watching him and helping look up features and have decided to start delving into ecu mapping. So this is my first step.
