I'm very familiar with my hondata s300 , but the one thing I want to figure out is how to read and record datalog. I have the D14 wire hooked up into my wide band but is it possible to make a few runs and read air fuel ratio from idle to red line and make adjustments?

 

Yest that is why you have a s300 and a wideband.

 

where can i find a write up on how to do this?
