This video shows how to install a wideband O2 sensor and how to set up a firewire with an SCT X4 programmer. This will allow you to be able to send datalogs of the AFR to a tuner or to log AFR for your own review. This was done on a Ford Lightning but the process is similar for almost any car using an SCT device with Firewire.
