Alright, So I am tuning my car with a maft with a blow through setup. I am using the stock o2 sensor to tune the car and a TMO data logger. When I drive the car normally with minimal boost(Regular driving). In the first the a/f ratio shoots to 20.0 and then goes back to 14.7 ish . I know 14.7 is the stoichiometric ratio for cruise. Im shooting for a 11.1 - 11.5 ratio which I do have. So should the ratio shoot to 20.0 at all? Also sometimes at idle the ratio might go up to 17 and then go back to 14.7 .
