Troubleshooting rich condition on both cylinders

[Jim Bronson]

Which PV channels should I record/analyze?
2013 fxdc, S&S 110, S&S 585, S&S intake, V&H 2>1.

Usual suspects. RPM, TP, ET, AFR (lambda) desired, O2F, O2R, KRF, KRR. Are you using widebands?

[Jim Bronson]

Using stock narrowbands.

[rigidthumper]

If you wish, you can set the AFR desired (lambda) table to 1.0 for testing purposes. Flash that in , ride & record. Look at the data to verify your system is able to hit/hold 1.0 @ the O2 sensors, or edit the VE tables until it does. Once satisfied, restore the AFR desired table.

Thanks ridgidthumper. That gives me a good homework assignment. 

[Jim Bronson]

I can't figure out what KRR and KRF are. Front and rear something?

[Coyote]

Knock Retard perhaps

[Jim Bronson]

I think that's it. Thanks.
