We're running a Haltech F7 on a 3 cylinder, 2 stroke motor. The unit bench tests to 9600 RPM (equivalent to 19,200 RPM for 4 stroke motor), but starts missing fuel injector pulses in operation at about 7800 RPM. Has anyone had any experience running F7 units at these RPM's? -- Douglas A. Yip Digicon Engineering Inc. http://www.digiconeng.com
