Bunchy1995 Posted August 17, 2018 Report Share Posted August 17, 2018 Hi I am currently converting my distributor style to coil on plug and wanting to control trigger inputs through a 12 tooth crank wheel with a hall effect sensor and a single pulse cam position with a hall effect sensor. Just wanting to know what the pinout is for both trigger one and trigger 2 Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 17, 2018 Report Share Posted August 17, 2018 I assume you mean at the ECU header, not the old distributor plug? Trig 1 signal = C12 Trig 1 gnd = C2 Trig 2 Signal = C14 Trig 2 gnd = C4 Quote Link to comment Share on other sites More sharing options...
Bunchy1995 Posted August 17, 2018 Author Report Share Posted August 17, 2018 Yes, thanks Adam, that helps greatly. do i need to run a resistor between switched 12V power and signal or will the pullup resistor on the ecu control this.

Adamw Posted August 17, 2018 Report Share Posted August 17, 2018 What sensor are you using? Quote Link to comment Share on other sites More sharing options...
Bunchy1995 Posted August 17, 2018 Author Report Share Posted August 17, 2018 Honeywell LCZ260 Hall Effect Sensor - 4.5 to 26 V dc - 20mA Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 17, 2018 Report Share Posted August 17, 2018 According to the datasheet that sensor has a built-in pull up so none will be required. Quote Link to comment Share on other sites More sharing options...
Bunchy1995 Posted August 17, 2018 Author Report Share Posted August 17, 2018 Thanks Adam, so i can disable the pull-up on the trigger setup, due to the sensor having an internal pull-up Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 17, 2018 Report Share Posted August 17, 2018 Yes I expect it will give best performance with the ECU pull up turned off. Quote Link to comment Share on other sites More sharing options...
