I tuned my VE table via a wideband and lost about 4-5 MPH on the highway. I did not notice ANY difference in the way the car ran, although the wideband was showing more numbers >14.7 than <14.4 with the tuned VE table. Going back to the previos VE table without making ANY other chnaged brought my fuel mileage back to where it was before I tweaked the VE table.
BTW - I know what I did wrong when I tuned the VE table, so I am going to try this again. The only thing I did was to unplug the MAF and O2 sensor, then scanned and used thre wideband to get the AFR to 14.7:1. I know now I need to make other changes in the VCM file before doing this.
