Discussion and questions related to the course Practical Standalone Tuning
Is there a process to calibrate the wideband sensor on the MS3? What I am seeing is a sensor reading of <8.1/1 A/F at all times. I have a Ballenger AFR500 to calibrate with and the wideband sensor read by my MS3 is not accurate to the AFR500. Leads me to believe there is a way to change the interpretation of the Wideband signal, or maybe a different wideband needs to be used.
This is on a 2004 Mazsdaspeed Miata, 1.8 turbo.
There should be a calibration table (based on the thread below, look under "tools"):
Here is a similar page with info for the Innovate wideband...
