Hello everyone, I’m sorta new around here. Last fall I purchased an 05(mk4) Jetta 1.9tdi, and I spent the winter converting it into an autocross kart, to play around with in the spring. With the build drawing to it’s close, I’m wondering if there’s any way for a tuning newbie (me) to edit the car’s ecu map myself. I’ve got a laptop and some tech know how, and it’s a process I would love to try for my own experience (as opposed to paying for a ‘chip’ tune or reflash. Please let me know of any software that can be used to play with ecu values, and share whatever tips and tricks you can! The engine is a BEW code (pd) engine, with the (correct mw of I’m wrong) Bosch 16 ecu. Thanks in advance to those who can help!
