408 tuning with a Wideband sensor
Drove the car to work after lunch today. It's probably about 15 degrees warmer than the last time I tested it. The idle and transition definitely got richer with the warmer weather. Here's what I saw on the meter
Idle 13.7-14.0
40mph 13.0-13.5
50mph 13.0-13.5
60mph 13.0-13.5
70mph 13.7-14.2
Seems like the transition is still rich. I put new plugs in before this drive. I put about 7 miles on them most of which were just cruising under light throttle between 50-70mph. Plug looks lean to me but I have little experience reading them. I also adjusted the valves tonight for the first time since break in. I'm happy to report that after 600 miles they haven't moved a bit. I heard that Hughes made great rockers and now I'm a believer.
