I have the old MPVI Pro I bought it way back in the day and added a LC-1 wideband. I recently started using it again after not touching anything tuning for about 10 years. I have a 70 Z28 that I put a 5.7 LS in and have been using it to get the car running. I don't really see the point in upgrading to the newer MPVI since this one works great. Since the LC1 is long gone, what wideband do you guys recommend for use with this thing?
