B1102 Torque Based Fuel LBZ

[Toodlums]

On a stock truck:

Looking at an LBZ B1102 Torque Based Fuel, we can assume that at least two values are accurate based on the engines rated power from GM: ~650lbft@1600 and ~580lbft@3250. What I want to know is are the mm3 values above the rated torque accurate? For instance, is the 3200RPM data beyond 590lbft accurate? If GM has mapped that out for us, it would seem like an easy way to get documented power increase without a dyno and without fudging the pulsewidth table.

Those numbers are just for reference they are not accurate.

I understand that they are not the actual fuel volume injected, so not accurate in that sense and merely a reference.

So what you're asking is can you just command a higher TBF to make "more" and a give power level?

If I go into pedal position to desired torque and bump up the torque at 3250 and 90%+ TPS, to 650lbft from the stock 600lbft, will it make ~650?

No. Not without changing all the other tables limiting fueling and timing.

Understood, I've looked at every fuel limit table in the file and augmented as needed. I haven't changed any of the timing tables.
