Ok so I have a sct x-cal2 and i notice when you plug it into you car it has a section called "data logging" or something along those lines. You can go to SCTflash . com and download a program that will show you parameters of your car. From the way it sound you plug your tunner into your car then hook that to your laptop and the same time using a usb cable and you should be able to get you parameters. does anyone know anything about this and if so can you get your air fuel ratio by doing this.

 

The car itself doesn't have a wideband so you wont get correct readings.

what does it take to install a wideband?

 

You need a wideband O2 kit. Dynojet, innovate and there is one by FAST. Autometer has a setup as well. They need to have an analog output that will go into one of the analog inputs of the XCAL. The mini din connector has the inputs.
Here is a link to all the ones Lethal Performance have. To install one, you need to drill a hole in the exhaust and weld a bung connector where the wideband sensor screws into.
