Hi Guys;
        The Tach saga continues. I tried a tach from my new snowmobile which is a computer driven signal, hoping that it would make sense of the hi-res. signal from the EC2. No dice. It shows zero while connected to the tach output or the coil trigger. A conventional 2 stroke tach also fails to register any signal from either of these sources. A Hastings Tach continues to read 3X actual from the EC2 tach output, but zero from the coil trigger.

        Now for the interesting part. I borrowed an inductive test tach (SunTune - an analog dial with settings for 2 or 4 stroke) and clipped it on the plug wires... and still zero. I tried all settings on all 4 wires under various engine speeds, but still nothing. I'm pretty darn sure that I've got good spark, 'cause the engine sure is smooth and powerful :-). My timing light has the same type of inductive clip for the spark plug wires and it works fine. The clip is directional (little arrow points to the plug) and I ensured it was on correctly, but just to check I even reversed it, but no luck. I checked the operation of the test tach on my Jeep and it works fine. So this leads me to question whether the Tiny Tach will work either. I guess Rusty will answer this question soon.  I've not yet received my programmable divider counter chip yet, but I sure hope it works. Currently on the AeroElectric list, the Tiny Tach is being discussed by others on a different application. As electric Bob is engaged in the discussion, maybe I'll throw this one at him.

        On a different note. all other tests are going well. Absolutely no cooling problems yet and the muffler is working very well. I've had many comments about how quiet it is. The prop noise is definitely louder than the engine, however even this is quiet as advertised (IVO, 3-blade) Obviously I can't tell you what my static RPM is, but I can tell you that even while standing on the brakes I can't hold it during a full power run-up :-) So far, I'm extremely pleased.

        Now if I can get this tach issue sorted out, I will call for my final inspection.
