David Tychsen-Smith Posted January 28, 2016 Report Share Posted January 28, 2016 Hi,I require a squarewave output to indicate when cylinder number 1 is firing or at TDC to input to another device. As I am using a G4 ecu on a 6 cylinder engine and only have 4 ignition drivers I'm running wasted spark, so taking a signal from ignition driver 1 will only tell me if cylinder 1 or 6 is firing. Can I use a spare injector driver to produce a squarewave that changes state at cylinder number 1 firing or TDC?Thanks for your time, any assistance would be much appreciated.Cheers,Dave Quote Link to comment Share on other sites More sharing options...
Simon Posted January 28, 2016 Report Share Posted January 28, 2016 Hi David Does it need to be timed accurately or will a single pules for one engine cycle do? Quote Link to comment Share on other sites More sharing options...
David Tychsen-Smith Posted January 29, 2016 Author Report Share Posted January 29, 2016 Hi Simon,Thanks for the quick reply.It needs to be timed accurately, preferably to Cyl1 ignition firing. Is there any way to configure an output to perform in this manner? Or possibly a way of distinguishing between Cyl1 / Cyl6? I could try combine this with the coil driver output and extract the signal. Thanks again for your assistance,Dave Quote Link to comment Share on other sites More sharing options...
Scott Posted February 1, 2016 Report Share Posted February 1, 2016 Is your injection sequential? Possibly you could use injection drive 1 in conjunction with ignition drive 1 to determine when is cylinder 1 and when is cylinder 6. Quote Link to comment Share on other sites More sharing options...
