Okay I am wanting to do this with my car and I am in need of some help. I know you need a cheap laptop that I already have, the aldl cable to hook into the port under the dash and into the computer, then what program to use. I have tunerpro rt and all I would have to do is plug all this in together and click on tools and aldl logging and go from there to see what my car is doing before I start messing with things on the chip? Let me know if there is anything else I need to do to see what my car is doing right now to get a base line on my car?
