Part Load 0.80–1.20 • Low Load 0.53–1.47 • Adaptation values maybe erased if the car battery goes low or is disconnected. • Additive adaptation is used mostly to correct idle mixture, however, it may also be used at higher RPM for fine adjustment (may see different additive values at different RPM. With relearn, it is normal for Additive adaptation to respond quickly. Multiplicative learning typically requires more learning time and vehicle must be driven on an extended road test under various driving conditions. • For most systems that have FT control using ±25% maximum range, readings above or below 14 sets a DTC and turn on MIL.
