ECMlink DSMLink V2 with Wideband o2

[eclpsegsx12]

Hi, I currently am running the dsmlink v2 on my 98 and when my motor gets done(built 6-bolt) along with my other goodies, i was thinking that getting a wideband might not be such a bad idea. I can get a really good deal right now through a friend of mine and i think i should jump on it. Bsaically, i want to know how much more effective is the wideband going to make my tuning off the dyno. I dont want to spend days on the dyno. I know the dsmlink measures a/f ratio but wha exactly is the difference between that and a complete wideband. What do you all think? How effective will it be for me? I am pretty familiar with tuning and most of the settings on the dsmlink also.

DSMLink estimates A/F ratio based on the airflow and the injector pulsewidth.

You'll be able to see your knock count. You really want to tune for zero knock, knowing what your exact a/f ratio is at that point of zero knock is a nice benefit, and if you have the money to burn then sure, get the wideband. But you don't need it.
