    Off-Road Race truck running a N/A Gord 363, 10.5:1 comp, AFR heads, blah, blah, Sniper EFI to Holley Digital Dash.
    It appears with Dominator you can run dual O2 sensors but what about Sniper EFI? And if not, is it possible to run a second WBO2 straight to the Digital Dash for monitoring only?
    I live at 5500 ft, so dyno & testing takes place up here, but races are at around 1K feet. Should I build two separate tunes or just put the system in Learn mode when I get down to lower elevation, and let it figure out running on the extra air.

    Only one WBO2 channel for the Sniper EFI. There is one "Custom 5V Input" (LINK), so if the aftermarket stand-alone WBO2 controller has a 0-5V output, it should work. Contact Holley Tech Service (LINK) to confirm this.

    I'd try letting it Learn first: http://forums.holley.com/showthread....5941#post15941 (Effect Of Elevation Changes On Fuel & Timing)
