Can I use a laptop if I want to do additional tuning?
Yes! BUT we recommend this for PROFESSIONAL TUNERS. FiTech is not a tuning school and we are not here to teach you how to operate laptop software. If you are a proficient tuner, you can do ANYTHING you desire with the laptop software including messing up your engine! If you are an amateur or even a well-rounded tuner you will have more than enough available at your fingertips, please stick to the Hand Held Controller. It is MORE than enough for 99.999% of users.
