I had just spent the last hour answering some of the points - went away to do something else - and lost the lot - so here's the second attempt. We have had exceptional results with the RTD (Racetech Developments) EMX-04 (for singles and tandem twins) and the EMX-05 for a 2 trigger system. Shame as it's a well priced and featured box. We did also try both coil outputs feeding into the single coil as suggested in Frits' comments, but it made no difference. I did speak with Ignitech and they couldn't shed any light on the difference and we did check everything at least 3 or 4 times. After the big difference we also verified the curves on the motor (by strobe). The curves programmed in are identical and were verified on our ignition rig prior to installation on the motor. The only other thing I could think was that a low spark energy was taking longer to actually fire the plug. As well as the lack opf power with the Ignitech you also see a big rise in the EGT's, which under normal circumstances I would say was due to a retarded ignition. We also triggerd this in the same manner. We powered the Ignitech with Lipo battery, rectified and regulated 13V supply off the Honda generator and both (which is actually illegal for us. The HPI is a 2-curve digital programmable CDI unit, just replacing the stock Honda unit and plugging into the Honda generator and taking the trigger off a raised segment on the rotor periphery. I know it's a bit off your topic, but I thought you might be interested to see a direct back-to-back dyno comparrison between an HPI and Ignitech ignition installed on one our Honda CR250 Superkart engines.
