An interesting and well written post, thanks for the link. However I still have three questions:
1. Is the purpose of the diag signal to allow visibility of the adjustment (whether richening or leaning) the system is making compared to the 50% base?
2. How to read duty cycle for this diag output?
3. Does residual O2 in the exhaust lead to increased CO too?
I think this thread answers 1+2 (thanks guys) but can someone confirm.
Much appreciated.
