Since I installed the Smarty, the Edge has been gauges only. I understand the Smarty programs without timing allows the Edge to be adjusted up for added timing and performance. So what actually does the Edge do with the various systems? How does it make it's power? And what does it not do? I'm concerned that when the Edge intercepts a sensor signal and modifies it to cause the ECM to react in a certain way might not be a good thing with the Smarty program installed and perhaps I should remove the Edge and add gauges. I sure would appreciate any suggestions that would help me mate the two together correctly. Tks in advance, John
