6. tooth width Therefore 2015 AEM Performance Electronics Tuning Guide 16 there are several considerations to take into account when calculating the desired Noise Cancellation values The shortest duration between edges is the first value to determine by examining the trigger wheels or signal outputs from the Crank Position Sensor and Cam Position Sensor s This means that either the shortest tooth or the shortest gap between teeth needs to be used in the calculation whichever is shorter in duration degrees What is important is the minimum time between edge transitions either high to low or low to high within the entire trigger wheel For a 60 2 even spaced trigger wheel the minimum tooth duration is 6 degrees 360 60 However the tooth is actually high for 3 degrees and low for 3 degrees Therefore the useful value here is 3 degrees This value will be used in Column D inthe table below which uses a 60 2 trigger wheel as an example The second important variable specific to each engine is the maximum Engine Speed RPM that the engine will spin to This is because the duration of each degree of trigger wheel in microseconds will be reduced as the engine spins to a higher RPM The maximum desired RPM needs to be used as the deciding factor and can be seen in Cell A12 in the table below Use the table below to calculate the desired Noise Cancellation value for the Crank Position Sensor for a 60 2 trigger wheel The RPM value
7. widths Therefore the calculation above is only a guideline and should not be used at the maximum limit The actual Noise Cancellation value may have to be 2 3 times smaller than the maximum allowed value to compensate for random noise injected into the signal To understand this idea more completely refer back to the figures above 2015 AEM Performance Electronics Infinity V95 August 2014 Update Notes CAN AEMNet The CAN AEMNet output is identical to the Series Il datastream with the exception of the analog channels below CAN works the ECU will broadcast the same CAN telemetry as a Series2 EMS If working with an AIM or RacePak dash configure the dash as though it was receiving data from a Series2 EMS No setup needed in the Infinity software it s always broadcasting Make sure you connect the dash to the CAN_A pins C1 31 and C1 32 on Infinity 8 10 12 Since the Series2 default stream sent a bunch of spare ADCR_XX channels and the Infinity similarly has a bunch of Analog_XX channels the Infinity s Series2 Emulation telemetry is already broadcasting lots of Analog_XX volts signals that might be useful to view these channels get broadcast on MessagelD 0x01F0A001 Series2 ADCR11 bytes0 1 gt gt Infinity Analog09 Volts pin C1 37 Series2 ADCR13 bytes2 3 gt gt Infinity Analog10 Volts pin C 1 38 Series2 ADCR14 bytes4 5 gt gt Infinity Analog11 Volts pin C1 39 Series2 ADCR17 bytes6 7 gt gt Infinity

15. s in Column A represent maximum desired RPM Assume for this example that you want to spin the engine to 9500 RPM Therefore you will use Row 12 to calculate the Noise Cancellation value From left to right the RPM is used to calculate degrees per millisecond the milliseconds per degree then microseconds between edge transitions and finally Noise Cancellation values based on 3 2us per increment At 9500 RPM and 3 degrees between edge transitions each transition will happen in 52 6 microseconds Therefore you can have a maximum Noise Cancellation value of 16 16 3 2us 51 2us A B C D E F G A 360 60 1000 1 B Ex 60 2 3 deg high 3 deg low C D 1000 Determined by SH chip E 3 2 200 RPM 1 2 degrees ms 0 8333 ms degree 3 degrees 2500 0 us microsecond 3 2 us NC point 781 NC max value 3 0 0 3333 3 1000 0 9 0 0 1111 3 333 3 15 0 0 0667 3 200 0 21 0 0 0476 3 142 9 27 0 0 0370 3 1111 33 0 0 0303 3 90 9 39 0 0 0256 3 76 9 45 0 0 0222 3 66 7 11 8500 51 0 0 0196 3 58 8 12 9500 57 0 0 0175 3 52 6 ON DU wn la w Another important consideration when determining Noise Cancellation values is that the values calculated from the table above above assume a noise free signal More specifically if noise occurs at some location in between edge transitions the effective tooth duration is split up by the noise ff a single noise impulse occurs 1 5 degrees into a 3 degree tooth duration then you will effectively have two 1 5 degree teeth
