[. . . ] For a throttle opening between the"Hi Thr"and"Lo Thr"setting values, the"Hi Thr" and"Lo Thr"air correction factors that are interpolated by the"Air Map"engine rotation speeds, which are further linear-interpolated by the"Air Map"engine rotation speeds, are used. These setting values are invalid for a vehicle with no throttle signals. Operations Select"Lo Thr"or"Hi Thr"with the Left and Right keys. Increase and decrease a set value with the Up and Down keys. Setting range LLo Thr: 0 to 99 (%) (in steps of 1%);initial value: 10 Hi Thr: 1 to 100 (%) (in steps of 1%);initial value: 50 * These values can be set as far as the relationship of Lo Thr Hi Thr is established. Outline of functions Change of the rate of correction by setup of the degree of a throttle. Difference angle of a throttle When it sets up to Lo Thr:10% and Hi Thr:50%, it is a throttle difference angle. 40%, engine number of rotations The rate of compensation of the air at the time of 3000rpm is as follows. * Setting example * Setting example 21 correct value +3% +2% ±0% 10% 40% 50% The open degree of throttle -1% 0 It can ask for the rate of air compensation whose grade which the throttle opened is 40% from the following formula. % % ×% % %% % % How to make a correction by engine RPM setting and throttle opening setting * Setting example Thr Point Hi Thr Lo Thr 80% 30% Air Map Ne01 Ne HiThr LoThr 500 2 -4 Ne02 1000 3 -2 Ne03 1500 4 -1 Ne04 2000 3 0 Ne05 2500 3 1 Ne06 3000 6 2 Ne07 3500 7 2 Ne08 4000 8 2 Ne09 4500 9 1 Ne10 5000 9 1 Ne11 5500 8 0 Ne12 6000 7 -1 Ne13 6500 5 -2 (Pro Mode) Ne14 7000 3 -2 Ne15 7500 2 -3 Ne16 8000 1 -3 If it is made an arrangement like the example of a setting, a map in practice as shown in the following table will correct. engine rotation speedrpm 500 0 10 20 30 40 50 60 70 80 90 100 -4 -4 -4 -4 -2. 8 -1. 6 -0. 4 0. 8 2 2 2 1000 -2 -2 -2 -2 -1. 0 0. 0 1. 0 2. 0 3 3 3 1500 -1 -1 -1 -1 0. 0 1. 0 2. 0 3. 0 4 4 4 2000 0 0 0 0 0. 6 1. 2 1. 8 2. 4 3 3 3 2500 1 1 1 1 1. 4 1. 8 2. 2 2. 6 3 3 3 3000 2 2 2 2 2. 8 3. 6 4. 4 5. 2 6 6 6 3500 2 2 2 2 3. 0 4. 0 5. 0 6. 0 7 7 7 4000 2 2 2 2 3. 2 4. 4 5. 6 6. 8 8 8 8 4500 1 1 1 1 2. 6 4. 2 5. 8 7. 4 9 9 9 5000 1 1 1 1 2. 6 4. 2 5. 8 7. 4 9 9 9 5500 0 0 0 0 1. 6 3. 2 4. 8 6. 4 8 8 8 6000 -1 -1 -1 -1 0. 6 2. 2 3. 8 5. 4 7 7 7 6500 -2 -2 -2 -2 -0. 6 0. 8 2. 2 3. 6 5 5 5 7000 -2 -2 -2 -2 -1. 0 0. 0 1. 0 2. 0 3 3 3 7500 -3 -3 -3 -3 -2. 0 -1. 0 0. 0 1. 0 2 2 2 8000 -3 -3 -3 -3 -2. 2 -1. 4 -0. 6 0. 2 1 1 1 At an opening below"Lo Thr", the same correction factor is applied. At an opening between "Hi Thr"and "Lo Thr" , linear interpolation is applied. At an opening over"Hi Thr", the same correction factor is applied. Throttle opening % 22 Dec Air * Only when VTEC control Off is selected If the throttle is rapidly released on a vehicle with a hot wire and Karman turbo airflow signals, the engine may be stalled by blow-back. If the throttle is rapidly pushed back, the airflow sensor may react to the blow-back, disturbing its signals, and then failing in fuel injection response to the deceleration, causing the engine to stall. In such a case, it is possible to prevent the engine stall by imposing an upper limit restriction on the airflow signals by setting"Dec Air"and then shutting off the airflow signals disturbed by the reverse blow. If the throttle opening goes less than the value set by"Dec Air"at a rotation speed lower than"Air Map"engine rotation speed"Ne 02, "airflow signals that are higher than the airflow usage ratio (or Karman turbo frequency) set in"Dec Air"are not output. * This function cannot be used for a vehicle with no throttle signals and one with selective throttle signals. * The engine stall is not prevented for a mechanical reason other than explained above. Outline of functions The sensor has read the air flux of throttle off depended for blowing. Airflow sensor signal input Actual air flux included in engine. Since an Air flow signal comes out greatly to actual air flux, fuel will be blown beyond necessity and engine will carry out a stole. Throttle signal Timing of throttle off The Air flow sensor signal output after correction of AFC neo. Since the waveform after correction of AFC neo approaches actual inhalationof-air flux, a stole can be prevented. 23 Operations Select"Thr" "Ne01"or"Ne02"with the Left and Right keys. This function is not enabled when"Thr"is"OFF. " This correction functions at a throttle opening less than the value set in"Thr. " The rotation speeds set in"Ne01"and"Ne02"are those set in"Ne01"and"Ne02"in "Air Map. " If a rotation speed in"Air Map"is changed, the one in"Dec Air"is also changed. (This change is enabled by"Air Map"only. ) Set an output upper limit for the airflow signals that are at the engine rotation speeds in"Ne01"and"Ne02"If an engine rotation speed is between"Ne01"and"Ne02, " calculate the upper limit for the airflow signals by linear interpolation. If the engine rotation speed is lower than that of Ne01 the upper limit for the"Ne01"airflow signals is adopted. This function is not enabled at an engine rotation speed that is higher than that of "Ne02" Set values of Air Map Ne01 and Ne02 engine rotation speeds Set value of upper limit of airflow signal output Set value of control start throttle opening Setting range Thr: OFF, 0. 1 to 20. 0 (%) (in steps of 0. 1%);initial value: OFF Hot wire type Ne01 and Ne02: 0. 0 to 20. 0 (%) (in steps of 0. 1%);initial value: 10. 0 Karman turbo type Ne01 and Ne02: 0 to 40 (Hz) (in steps of 0. 1%); initial value: 20 * Setting of rotation speeds conforms to that of Air Map engine rotation speeds Ne01 and Ne02 24 V/T Control * Only when VTEC control On is selected VTEC setting points of a VTEC-installed engine can optionally be set. One is an engine rotation speed at which the VTEC is switched from the Lo cam to the Hi cam. The other is one at which the VTEC is switches from the Hi cam to the Lo cam. These points can optionally be set irrespective of genuine switching points. When a specific intake pipe pressure (or airflow usage ratio) and throttle opening are exceeded in addition to the VTEC switching by engine rotation speed, the VTEC can be switched from the Lo cam to Hi cam. Operations Use the left and right keys to toggle between items and specified values. Pressing the DOWN key while the cursor is positioned in"Lo -> Hi"or"Hi -> Lo" displays"No Control"and disables the"V/T Control"function (ECU VTEC control becomes effective). Pressing the UP key while"No Control"is displayed releases"No Control"and enables the"V/T Control"function. [. . . ] The following signals are displayed and checked: ignition power voltage, airflow signal input 1 voltage, airflow signal input 2 voltage, throttle signal input voltage, airflow signal output voltage, position lamp, VTEC input, Karman turbo, and engine rotation. Whether wiring is normally made and the status of each sensor can also be checked. Operatings Press the Up navigation key (PRV) to go back to"Display Setting Select. " Measured voltages are displayed respectively in"IG, " "In1, " "In2, "and"Thr. " "Out"displays an airflow output signal voltage that is actually output. "Lamp"and"Vti"display input signal On/ Off.
