EVOscan Wideband readings different from Fuel Map AFR

[BostonGST]

Getting into tuning and have done tons of research and understand most of the concepts, just am unsure on a few things. One is my wideband readings are different that the fuel map afrs. I know the 02 feedback trim is how the ECU changes fuel based on 02 readings. To get the fuel maps to match the wideband do I change the MAF scaling? And for a 02 feedback of 6% how would I change the scaling?

Using Evoscan/ECUFlash with evo8 ECU

1). Any boost, vac, or exhaust leaks?
Did BLT all good, also boost gauge reads 20 vacuum when idle

4). Ignition system
all stock and changed with correct spark plugs about 3k miles ago


6). Performed basic throttle body adjustments?
idles good no idle surge



8). Any known bad sensors or brittle wiring?
everything good

11). Base fuel pressure and injector values
stock injectors and pump

12). Properly calibrated and configured wideband sensor
widebands hooked up and reads properly, o2 sensor is from AEM Eugo (set to P04) and in stock front 02 location

13). Type of fuel
California 91 Octane

Log is attached.

Fist off what tuning tool are you using? and second if its ecmlink posting a log does wonders on these boards there are a few link gurus here that can certainly help you for sure

Not only posting a log but filling out the supplied template when you start a new thread is the only way you will recieve advice from many of the knowledgable members on this board. Help us help you and give accurate information when filling out the template.

Your profile lists no tuning method so I assume that should be updated as well.
