INT - Integrator & BLM-Block Learn Memory

Normal readings for these positions are approximately 128. Higher readings indicate the ECM is adding fuel to the base calibration, while lower readings indicate the ECM is reducing fuel delivery. The integrator (INT) reading is short term correction and the readings vary when the ECM senses a need for fuel delivery correction. Block Learn Memory (BLM) is long term correction, and readings should only change if the integrator monitors a need for correction that lasts for a calibrated period of time. Normal BLM readings are 128-138.
