Newbie tuning questions Hello tuning experts, I want to make the jump into DIY tuning. My car isn't heavily modded yet (lid, headers, catback), but I want to get a handle on tuning before it is. I plan to purchase HP Tuners VCM Suite Standard and a wide band O2 setup. A few questions: 1) What wide band O2 to get? I've been looking at www.innovatemotorsports.com and www.widebandcommander.com. 2) This may be a stupid question, but when logging with the wide band, where do you connect the O2 sensor? 3) Is this a good way to go? Any suggestions for another route or other stuff I need? Thanks in advance.

The Innovate and I believe WB Commander both log
internally and let you hook to PC. I saw on the WB
Commander website that they were out of stock on
that unit? Anyway, both of these will output an
analog voltage that you can feed to (say) your A/C
pressure sender connector (0-5V) or one of your rear
O2s (if it's 0-1V). The A/C is easier to get at. I would
go that way. You may need to get a bung welded in
unless you use the tailpipe mount ($ or cobble). I
don't know whether the post-cat AFR reading from a
wideband is considered as valid a tuning read as
pre-cat (using the front O2 bung I guess; issues w/
closed loop normal operation then?). I think a lot of
the dyno wideband reads are tailpipe so maybe it's
no diff?
I am leaning toward the Innovate unit myself, on
price and portability; the WBC unit looks more like it
wants to be permanently mounted and only portable
reading is by the remote gauge (?). That, and the
out-of-stock situation. But the WBC does give you
the dash gauge as part of the deal where Innovate
prices that ala carte.
