2. P Connectors Insert the male connector from the SmartM AP into the female connector of the SmartMAP wire harness You should hear a definite click sound when the two connectors are properly mated Step 6 Secure the SmartMAP The SmartMAP is supplied with an adhesive foam backing that should be used to secure the SmartMAP housing to a flat surface As an alternative the housing can be secure to any other surface using a large nylon wire tie Secure the SmartMAP wires to the vehicle using small nylon wire ties Trim all excess nylon wire ties with the wire cutters HOW TO BYPASS THE SMARTMAP If the SmartMAP needs to be bypassed disabled at any time it is easily achieved by unplugging the SmartMAP male connector from the SmartMAP wire harness female connector Then insert the supplied shunt plug male connector into the SmartMAP wire harness female connector
3. e the MAP sensor on the electrical wiring diagram The MAP sensor typically has three wires with the following labels Reference Voltage VREF or VCC MAP Sensor Output Sensor Ground GND Using the electrical service manual locate and identify the MAP sensor wires that go to the ECU Step 2 Connect SmartMAP White Blue and Yellow Wires The SmartMAP is connected inline with the MAP sensor output wire Cut the MAP Sensor Output wire and connect the white blue and yellow wires from the SmartMAP wire harness to the MAP sensor wires as shown in Figure 2 The connection should be made closed to the ECU in order to maintain signal quality Lengthening the white blue and yellow wires to the SmartMAP is not advised It is recommended that the white blue and yellow wires be soldered to the vehicle wire harness instead of using solderless crimp connectors A soldered connection will be a more reliable connection compared to a crimp connector made with a non professional type crimper After soldering the wires wrap the connection with electrical tape and secure with the small nylon wire ties Step 3 Connect SmartMAP Black Wire Connect the black wire ground from the SmartMAP wire harness to the MAP Sensor Ground wire Use the MAP sensor ground wire instead of the chassis ground to maintain the best signal quality Lengthening the black wire to the SmartMAP is not advised It is recommended that the black wire be soldered to the vehicle wire harne

5. t atmospheric pressure wide open throttle for normally aspirated NS X s With a turbo or supercharger installed the manifold pressure will increase above atmospheric and the MAP sensor voltage will rise above 2 7V At some voltage above 2 7V the NSX ECU will assume that there is a problem with the sensor and shut off the engine since under normal conditions without the turbo SC the MAP output will never exceed about 2 7V The SmartMAP model SM 300 275 prevents the ECU from shutting down the engine by limiting the MAP sensor voltage to the ECU to 2 75V 0 0 15V Application for the Acura Honda vehicles The SmartMAP model SM 300 275 was originally designed for the Acura Honda NSX It should also work on other Acura Honda vehicles that have a MAP sensor with a similar output voltage as the one in the Acura Honda NS X Features e Replaces unreliable mechanical check valve restrictor assembly with reliable solid state device e Clamp voltage preset and accurate no adjustments needed e Fast response time much faster than any mechanic device e Easy SmartMAP removal with the use of supplied shunt bypass connector Specifications Current drain Less than 0 01 amps Ambient operating temperature 20 C 4 F to 450 C 122 F Specifications subject to change without notice ZUBLIN Figure 1 SmartMAP Output Waveform model SM 300 275 oo stopped 1 500 mv div BH lim 1 500 X 10 00 1 1H dc mou ee E
