  • Page 5: Introduction

    Introduction the air-fuel ratio combustion monitor (afm1000) the ecm air-fuel ratio combustion monitor (afm1000) was designed for the professional calibration of carburetor or fuel-injection systems. Using a state-of-the-art, wide-range uego (universal exhaust gas oxygen) sensor, the afm1000 provide...

  • Page 6: Important Operation Notes

    Important operation notes 1. Before installing the uego sensor, apply a small amount of non-lead containing antiseize compound to its threads. Do not get the compound on the sensor's tip. 2. Do not operate an engine for more than three minutes with the uego sensor in the exhaust and the control modu...

    How to use hooking-up the afm1000 location of the uego sensor the uego sensor should be located approximately 12" from the exhaust valve(s) of the engine. A location further from the engine may be used as long as it is at least ten times the exhaust pipe diameter upstream of the end of the exhaust s...

    Power the afm1000 requires clean dc power of 11 to 28v at 1.4a (steady-state). During sensor warm-up, the requirements are approximately 5a for a period of up to 1 minute. A good car or motorcycle 12v battery can meet these specifications. An ac/dc power supply is available (p/n 1000a-7). The suppli...

    Afrcorrected = (afrmeasured + b x p) / (1 + c x p) [equation 7] where: afrcorrected = the afr corrected for exhaust pressure. Afrmeasured = the afr output by the afm1000. B = 0.009140 for afr b = 0.012100 for afr ≥ 14.57 (lean). C = 0.000627 for afr c = 0.000830 for afr ≥ 14.57 (lean). P = the exhau...
