Your PCM requires NB sensors. Wideband is for tuning or reference to the layman. Some guys swear they can tune by the NB sensors just as accurately as a wideband. As for Innovate, I guess you get what you pay for. Honestly, I would trust the opinions of professional tuners rather than guys like me that just play with tunes. I would call on the larger shops or tuners that do 10 or more tunes a week and ask their opinion on which wideband to go with. I know the entry level Innovate LC1 was supposed to be troublesome. I have a FAST unit myself and since I only play with it I can't really give any opinion of its performance other than that it turns on when I tell it to and never misses a lick.
