Thread: Sequential Injection Phasing

  1. #1

    Default Sequential Injection Phasing

    I've read through all I could find on this, and still have some questions. What does the phasing of the cam sensor (single pulse Hall-Effect) have on the injection? Example: I'm using the 60-2 wheel set on the 11th tooth and have the sensor at about 190° BTDC #1. The car is up & running, is it correct? What difference would it make at 110° or 240°? Should I be using my cam specs to figure it out closer? Does it matter what tooth your using on the crank wheel as 0? Thanks, Russ

    All the cam sensor does is tell the ECU where TDC Compression Stroke is, so that it can use a Sequential Timing & Fueling Strategy. As long as it falls within a 30° either side of where the instructions say it is supposed to land, it will work just fine. Other than that, it doesn't affect anything else.
