Default Holley dominator tuning with boost




Trying to tune my LSX 427 under boost with the holley dominator setup with dual wide bands. Ive noticed in my logs that the AFR is not steady. I'm running in closed loop so its using the average of both WBO2 sensors and the AFR seems to jump around more than I like. I have the target AFR at 11.3 and the actual afr seems to jump around form 10.7-11.7 during a run. Is this normal since the wbo2 are making corrections to the fuel table?

Normal. It’ll steady as your tune gets closer.

Don't use an average. The Dominator is more than capable of doing per-bank fueling.

How can you set up the WBO2 for per-bank fueling?
