Jacky Fung Posted June 1, 2021 Report Share Posted June 1, 2021 Dear All, Since I have some problem w/ Monsoon G4x and AEM EPM as trigger signal on a civic B20. So I would like to try back to OBD2a Stock Distributor. I'm confused w/ the AEM and stock. If AEM EPM to Monsoon or plugin, only 2 cable back to ECU In stock distributor, there are 6 wire from distributor to ecu Stock Distributor OBD2A ECU 2. Crank Position Output - C2 CKP Sensor P-Side 3. TDC Output - C3 TDC Sensor P-Side 4. CYP Output - C4 CYP Sensor P-Side 5. Crank Position Ground - C12 CKP Ground 6. CYP Ground - C13 TDC Ground 7. TDC Ground - C14 CYP Ground Would you help to figure out, how can I connect Stock Distributor to Monsoon? Do I need connect a IGN or 5V to P-Side? Thanks for your help since I'm really confusing now.

Adamw Posted June 1, 2021 Report Share Posted June 1, 2021 You only need 4 wires. We need to reverse the ground and outputs since the honda outputs a rising edge waveform and Link needs falling. Honda distributor pin 2 & 4 = Link sensor ground. Honda pin 5 = Trig 1 Honda pin 6 = Trig 2. Quote Link to comment Share on other sites More sharing options...
