Thanks ! You have helped me so much! I really appreciate it. I was also trying to figure out what my spark should be set at for best performance.

Okay. So I have another question. I need to know how to set my short & long term fuel banks and what they should read. Because where they are set right now Short terms are between 0 & -2 for both banks, and long term on one reads 12.50 & the other reads 10.70.

I have the U7193 for my 04 Corvette with the 2.10 ver. on it. I have been trying to view the real time data on my laptop and I cant get the predator to connect to my laptop. What do I need to do to be able to use the predator with my laptop?

I have a 2004 Corvette .I am using a U7193 and I have been trying to use it with the Dataviewer. But the dataviewer just continues to say connecting. It never connects. I have unplugged and tried it all over time and time again. I am using Vista. Is there something that I'm missing.
