Six_Shooter Posted October 9, 2008 Share Posted October 9, 2008 I recently purchased a JimStim-K from DIYAutoTune.com (happy with how quickly the order went out ), had fun assembling it, and it works well. I'm not using it with a Mega Squirt, I am using it with a GM ECM right now and it's working pretty much exactly how I wanted it to. Now the issue I have is that the code I am using in the ECM seems to have limited output display to the datalogging. I need to verify the actual RPM at which something occurs above what is currently being displayed. What I would like to do is drive a tach off the JimStim in addition to ECM, so that I can have a display that shows me actual RPM. Will this be a problem? I'm thinking that it won't be, since the trigger to the tach is usually a high Z input and only used for "sampling" the coil input or tach output for a reading.
