Racepak O2 sensor

Willyracer · 06-22-2020, 11:30 PM

Have added a single O2 sensor to a racepak sportmans unit.
It is mounted on the collector just after merge.
Running a BBC on C12. I know location is not the prime
Spot.

I am only taking values above 6000 for comparison since
The sensor is in the collector.
The "lowest" reading I very see is 13.8 and that is only in
High gear at higher rpm
What values should I see and does the motor load effect
The AF value. The 13.8 is lean correct? But plugs look
Ok. Haven't tried bigger jets let but will soon now tracks are
Opening up

Thanks
David
