I'm wanting to invest in a scanner so that I can get some baseline readings for my vehicle before I start modding. What are some of you using for CAN vehicles, AutoEnginuity, AutoTap? What are your impressions? I'm leaning towards AutoEnginuity atm, but don't know how I'm going to be able to data log while driving. Aren't the connections for CAN and OBDII vehicles under the hood?
