Im using the white wire from the AEM and connected to the red wire from the firewire. I am getting good readings during datalogging but it seems to vary a bit from what the gauge says at WOT. JRE wants me to be sure that they read the SAME before doing any more changes to the tune. How do I make sure that I am reading my values correctly at the gauge and the output that is seen in LIVElink? IS there an equation that has been a proven performer to set in the analog 1 position?

Running the Ground to the engine block gives a cleaner signal than grounding to the dash chassis.
What equation are you using Now?
With some one riding with you they can view what the log says vs what the gauge says they should be the same within a 1/10 or so but they move very fast.
