I've been contemplating the purchase of a wideband O2 sensor and data logger for use in tuning the injection on my van conversion ( www.my.tbaytel.net/guskers ) and autocross car. The two I'm gravitating towards are: http://www.plxdevices.com/onlinestore_domestic.htm and http://www.innovatemotorsports.com/lm1.php Anyone out there used these or similar devices? They would seem the only way for a hack like myself to accurately tune air fuel ratios. I do have a O2 sensor monitor ( http://my.tbaytel.net/guskers/gauges.html ) and would agree with Frank C. that these are very inexpensive devices that tell you a great deal about the health of your fuel management systems. They don't however, offer much with respect to reliable assessment of A/F ratio outside of 14.7:1 Here's a great article on the subject: http://my.tbaytel.net/guskers/Real%20World%20Air.htm www.autospeed.com by the way, is one of the best "techy" car mags I've come across. The subscription (online) was money well spent. Their older issues are free. |
