Hi folks. Glad to be here, as cars are my hobby, and i am more interested in to electrics. I have no problem install alarm system , or do diagnostics, so time to "grow up" , i decided explore ecu programming world, as thats is something new and interesting for me. At the moment i have access to vw / audi group diesel cars (10- 13 years old) which i am planing explore and try do ecu mapping. I have ordered KESS obd tuning kit version 4.2 . Before i receive it, any recommendations ? Also wondering , is somewhere to download maps ready to go in? Or each car has to be mapped individually ? Assume everything is stock . Thanks.
