Hello,

I am not sure what the desirable long term fuel trim values are
for (manual transmission, 2000 LS1 engine, F-body):

1. car fully warmed up, car at idle for several minutes
(when near stock my car would gradually go to +22...24% from whatever value it was when driving

2. car fully warmed up, light load, light throttle, say 4th gear going 45 mph

3. car fully warmed up, WOT (or in PE mode)

Maybe there is a reference table where the LTFTs are supposed to be versus the fuel cell numbers?

Thanks,

Gert
