Fuel Trim info "help" page . . Images would be helpfull.
Fuel trim info page talks about 2 fields in block 32.
When I measure that block on my 2.8, I'm seeing 4 fields each with different values.
For me, I've got 3.1%, -3.1%, 2.3% and -5.1% . I get about 150 g/s on my MAF reading before readline.
Sure would be nice to have more detailed examples of possible scenarios for diagnosis.
