As stated, a wideband is the best bet for tuning... you could buy dyno time and use their wideband... but the 200 bux for an LC1 is a matter of what 3 maybe 4 hours dyno time tops? (proly more like 2 hours)
If you have your own wideband you'll constantly be able to check your AFR
yup...with how much the prices have come down over the past 3 or so years theres almost no reason not to have on in your arsenal.

Ok, well I am new to efilive tuning. New to tuning all together and I just received my software today and was told this is ALL I need to do the tuning, but after reading in the tutorials seeing that I MUST use a wideband O2 made me wonder. Guess I`ll be ordering the wideband sensor. What about my truck that I wanted to do some tweaking on? I really don`t want to get into a performance tune on it.

As mentioned its "not compulsory", but its pretty "essential".
By all means see how you go without it, but once you have tried tuning with one you will wonder why anyone bothers without one.

Verdad Gallardo Sorry about the tearse comment, I could'nt resist. On your truck, when you say you want to do some minor tweeking, I take it that means doing anything but Air Fuel corrrect? If so, yes. But that's not why you bought EFI live now isn't it?

That's very good.
A wideband tells you your true AFR which is what should influence any changes you make to your tables.
Even carburettor people have started using widebands to better see how a jet change is working.

LMFAO!!! I thinks thats the best analogy Ive ever read.
I bought efilive to tune my t/a, make some improvements on my truck and tune my ls1 67 camaro and my boosted ls2 69 camaro. I want to change some stuff in the factory tune on my truck, but I want to tune the t/a across the board. I think the old laptop I am using is the culprit in the problems I`m having, so I`m about to head out and get a new one today. I am new to tuning and want to learn every aspect of it and that includes doing a maf tune. I feel that would be the better place for me to start. Plus, it`s lighter on my pocket for the moment, which is what I need considering I just bought efilive thursday and am about to have to go buy a new laptop.
