mashio Posted October 11, 2021 Report Share Posted October 11, 2021 Hi all, I am new with Link ECU. I am using Link G4X Xtremex wire-in with Mazda RX-7 S6. I tried to set up trriger calibration, but I could not find clearly OEM marks on crank angle sensor plate. So I am thinking of setting up a trigger calibration by observing the crank angle signal G and the leading ignition signal with an oscilloscope. Since the crank angle signal G of RX-7 indicates BTDC +5deg, If the leading ignition timing is set to +5deg by Link ECU, the falling edge of the crank angle signal G and the falling edge of the leading ignition signal will be at the same timing. Is my understanding correct? I attached image of the waveform. Mashio Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 11, 2021 Report Share Posted October 11, 2021 There should be quite a big clear "V" notch in the trigger wheel, this is 20ATDC. Quote Link to comment Share on other sites More sharing options...
