Could someone please help me with a few questions I have about the SCT. OK, what exactly is data logging, how do you do it, and what is it for? (I have brenspeed tunes) Also I have installed JBA headers and now I am getting a CEL which reads 2197. Brent said this is due to a manufacture defect in the 02 placement.Anyone else having this problem with their JBA's?

 

Data logging is when you record the functions of your engine fora duration to use that information to make appropriate tuning adjustments. I am currently learning more about it but would not do any of my own timing/mass air/fuel/spark adjustments at present. These things are best left for someone who know's what they are doing. At this point I don't have that kind of confidence in myself. So I rely on a tuner. Someday I hope to learn enough to make those types of adjustments. But for nowI will be staying with folks who have the knowledge and ezperience.
