Re: wideband 02 sensor/data logging
Wide band O2 can be a great tool. Just like anything else, it depends on where your A-F ratio is now as to to how much improvement.
I sell the Racepak and Innovate lines.
If you are looking for the most economical setup I recommend the older LM-1 for race cars with MSD ignitions. They are $279 you can add RPM for $99.
Racepak has a O2 sensor to go into any Vnet system and they are $359.
I have had customers make major gains with cars that are setup for big wheelstands and had some issues with float levels. Also, several guys were able to determine intake manifolds with very unequal fuel distribution.
