TBI WBO2 Tuning- Dyno Results

[Fast355]

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.

Set the minimum temperature all the way up and the RPM all the way low.
