so i have a 2002 Z28 that was tuned in Speed density rather than using a MAF and id like to start logging data and smoothing out the tune a bit. Car definitely needs some tuning as its been maybe 10 years now and i have to add this will be my first attempt at logging and making adjustments. never logged data before so if anyone can guide me in the right direction to selecting PIDs and how to go about all this thatd be awesome! 100% rookie here and thankfully this car is now a test dummy rather than a priority. so im not too worried about learning tuning with this car.
