blm tuning help..

[1500chevy5.7l]

ok so i keep trying....to at least get a constant blm/int and as soon as i get my blms good my int hits extrems of 140+ to 110- but blms are pretty close... so i adjust blms a bit more and get my int close and blms look good then it seems like for no reason blms hit extrems like 117-145+ and int will be 127-129 whats going on....ecm is 7747 using tuner pro rt

INT = Short Term Fuel Trim
BLM = Long Term Fuel Trim

The Integrator follows the output of the O2 sensor by using the 02 window terms. If the 02 sensor is lean, the INT rises, if the 02 sensor indicates rich the INT falls. The BLM tracks the INT, if the INT stays continually lean, the BLM will rise, if the INT is constantly rich, the BLM will fall.

The swing is due to AE and DE being off, as well as maybe a lean or rich spot in the VE table.

I would get the BLMs pretty close 126-130, then disable them by setting the min/max BLM to 128 in the bin. Then fine tweak the fuel table with the short term fuel trims, INT alone.

AE= Acceleration Enrichment
DE= Deceleration Enrichment

AE= Acceleration Enrichment
DE= Deceleration Enrichment

very close, it Deceleration Enleanment, the opposite of Acceleration Enrichment.
