I upgraded to Xfi with the motor change, over the summer. The problem is with A/F... I have a eDash for the Xfi and it reads A/F of 9.7-10.8. The target reads 12.8-14.4 The car is setup to run on pump gas and Alcohol.. If the target is asking for a 12.8 and it is reading 10.3 what needs to be changed??
