I had a feedback from Dynojet tech support; they confirmed that using the spark learn feature with stock O2 sensor is not a feature to be used.
As far as concern the .25 retard I'm having in the front cylinder, I went trough the log and made a MAP/RPM table to identify in which area I have the problem realizing it is all trough the mid-range zone.
I will use the quick tune strategy adding 5%. Fuel and -4 spark in the area and see how it goes with a new log as per dynojet procedure for resolving ping issues. As per dynojet instruction I will set the log to highlight the spark event counts and corrections.
Because actually the rear cylinder is fine, if I see something bad happening in that area then I will go back and I will modify the front Cylinder only.
The lesson learned is that with the slip-ons and the K&N filter in the stock housing, the AT narrowband came out perfect automatically while with a full stage 1 AC the powervision requires manual adjustment.
