malcolm ward Posted July 25, 2011 Report Share Posted July 25, 2011 I have just installed a link onto my holden 5l vn engine. I am just wondering if it is possible to fire the injectors in sequential without installing a crank angle sensor. Is it possible to just use the standard hall sensor?

Simon Posted July 26, 2011 Report Share Posted July 26, 2011 The short answer is no. To get sequential you need some sort of reference so the ECU knows what TDC it is on. This is normally done with a second sensor. In this case fitting a crank sensor and modifying the existing trigger would be the best option. Having a crank trigger will also give better timing stability. Quote Link to comment Share on other sites More sharing options...
malcolm ward Posted July 26, 2011 Author Report Share Posted July 26, 2011 ok thankyou for that. Will altering my sensor by removing one tab and setting it up as a multi tooth missing tooth work or will i definetly need the second sensor?

Simon Posted July 27, 2011 Report Share Posted July 27, 2011 To do multi tooth missing you will need more teeth that what you currently have. (needs to be ideally at least 2 times the number of firing events) If you did make a disc with say 16 teeth and then removed one. That would work.
