I was wondering if there is a preferred device for OBDII error code checking and engine parameter monitoring?

I have come accross the following:

http://davisnet.com/drive/products/drive_p...t.asp?pnum=8221



I wanted to be able to monitor Air / Fuel ratio on my '05 to determine if it runs waay rich, etc.

I didn't want to spend money on a reflash if my ecu is already doing a good job.

Anyway would be nice to have this for future projects. :)

I have a laptop I can use for viewing the output. I don't really want an LED display or anything.

to see your air/fuel ratio you need a wideband o2 sensor. i use a plx m-300 on my 240sx it has a good price and great display. for a little more money you can wireless and datalogging widebands

you can also go to a dyno, they use them in your exhuast pipe

factory o2 sensors are narrowband which arent very accurate at all. mainly jsut switch the ecu from open and closed loop maps (closed being idle and cruise, open being wot)

:) haha.. i realize that.. but don't the '05 Z's have a wideband?
wasn't that a change for the model year?

That's what i'm after, something that will read it from the oem wideband sensor.

I just got a Blitz R-VIT from Gruppe-s . It looks to be an awesome tool. I'm not sure how it will work with the wideband setup on the '05.


thanks!
