theres a guide on the innovate website for hooking it up to datalogit, can use the same guide for whatever wideband you have. but whatever you do make sure the afr values showing in datalogit are the same as the ones showing in the widebands program before you do any tuning, when i first hooked myne up (accoridng to the guide) it was out by a fair bit.
as for the afr values in the fuel map, ignore them for the most part, as said they're a rough guess at best without adjusting the afm curve to suit.
