LS ECU options

[71RS/SS396]

Tim, are you talking about the HP or the Dominator.....or both?

I believe the Dominator has the option to connect 2 O2's, but it's an option, I don't THINK it does bank to bank tuning. Most of the aftermarket ecus I've seen ultimately get the tune all jacked up over time if you leave the O2 correction turned on. Get the tune right and leave it alone, no reason to keep fiddling with it imho.
