a/f ratio in pra ecu

Post by contectr »

HI..
i have see that it's possible to see a a/f ratio in a pra ecu with so2v...
(so2v * 2)+10 = a/f ratio..
but at full load i have 0.94*2+10=11.88 a/f..it's too rich...

The secondary o2 sensor is a narrow band sensor and does not tell you anything other than "above stoichiometric" or "below stoichiometric".
