The screen shots above are "Closed Loop" averages.

It looks like you're tuning with PE/AE disabled? I assume you tuned with WOT too?

[dave w]

The WBO2 Excel Spreadsheet is using Average IF formulas.
Average IF AE = Inactive
Average IF PE = Inactive
Average IF PE = Active (for WOT)
Average IF Closed Loop = Yes
Average IF Near Idle Flag = Yes (for Near Idle)
Average If Near Idle Flag = No (for Off Idle)

Dyno makes life so much easier this was a dirt track car with a v6 block that i road tuned in a paddock with wideband vs an hour on the dyno cleaning up only fueling nearly 40hp gain and 75 ftlb of torque its a huge change to how it drives that's for sure lol leaning it out from 12.5 to 13 gained 1 to 2 hp so I left it at 12.5:1

I have yet to find big gains dyno tuning anything. I have also yet to see big gains tuning anything with a wideband compared to how I tune off the integrator. I did find about 25 ft/lbs at 1,500 rpm in my Express van years ago but that was purely from the fact that area was not tuned at high load because it never ran at that RPM on the street at high load.

Hmm, would you care to share your Integrator tuner?

Fairly easy actually. Disable BLM and use the Integrator to tune the same way you would BLMs. On OBD2, BLM is Long Term and Integrator is Short Term. Delay PE until 90% throttle like the factory Vortec engines and set the RPM to enable PE delay if applicable to 5,000 rpm like the 6.0L LS. Integrator reponds 10x more quickly than BLM. When you enable PE the air/fuel mixture drops right in line where it should be.
