Scan Gauge II and Protium Gas Optimizer ?
 

Does the scan gauge really do anything but monitor your computer and does the optimizer really work ? If both of these units work, how hard are they to hook up ? I am just wondering if they are worth it.
Thanks,

Are you looking at an ebay auction, perchance?

The SGII is FE's best friend, but the protium gas optimizer is a piece of junk. Just get the SGII.

Listen to SVOboy. The SGII will pay for itself because it will help you to become a better driver. That's good for 10-20% MPG improvement alone. Bio-feedback for you and your car.

yes, I was looking at an ebay auction . So, the Protium Gas Optimizer is just a hoax ? THis is why I am asking you guys. I will fill out my bio in the next couple of days but I have to go to work now.
