Hello, Im new to TunerPro and well...tuning. I finally learned how to connect my ELM327 cable with the software. I would like to change the Idle speeds and mostly the speed limiter. Im working with a 2005 Hyundai xg350, yes Im changing the limiter on the car, lower. Im hoping someone can help and possibly teach me how to make changes to the ECM. Im not sure how to flash using tunerpro, I know you can, but haven't found a good explanation. all I plan on changing with the flash is idle, speed limiter, and possibly fuel/air ratios. Please remember I know very little about tuning, thanks!
