Anyone know where to get a good quality one? I wanna try and get one that will give me a good readout of MAP sensor reading, RPM, and Spark advance. I want to get a good idea of what our cars run before i have to go tune my haltech provided i ever get it installed. Or, if someone has a datalogger, would you be willing to help with this? I know i can't use one on my car, cus i have OBDI, but i was gonna use it on my buddies 97. If someone else wants to help though, god would it make my life easier.
