I suspect Tracy's PIC has its hands full at high RPM
reading this :) The single pulse by it self is probably
rotor one. The wide pulse is probably rotor 2.

I have no idea what Tracy is doing. He probably
considers the single pulse is the same as the
old 2nd gen crank angle sensor.

The easy way is to use 2 or more sensors, one for
each rotor, with only one tit on the wheel.

The pictures say it all. The router motor and
Harbor Fright (:)) motor control is the hot tip.
This thing runs smooth to ungodly RPM's (up to
22,000) thanks to Jim Poole's accurate machining.

If you want a RX8 trigger wheel hub and you need to ask
the price you can't afford it :) I have a spare one.

It is putting out a very strong signal with .2 inch
between the sensor and the wheel. On the order of
8 volts peak to peak. That is a stock, high buck, RX8 sensor.
Ill try it soon with the cheap $16 ABS sensor.

Be careful. Don't let it come apart. It can kill.

Paul,

That's great progress.  I would be interested to see what effect a
non-concentric timing wheel would have.  I found that mine had a
.0012-.0013" variation in the gap.  I decided to go ahead and switch over to
the Renesis water pump which will use the Renesis trigger wheel and hub.
This should cure the problem with changing gap, and possibly cure the miss
too.  It sure won't hurt anything.  ;-)

That out of round is not going to help. It will vary the amplitude
of the signal once per rev. Jim Mederer tells me that is a common
problem with the e-shaft on the 3 rotor.


Good idea to go back to the 2nd gen CAS. Does Tracy have a different
software package for that or will it work with either?

I have no idea what Tracy is doing but reading the RX8 trigger wheel
and firing a three rotor is not an easy  thing to do in software.

How are you coming with the Hytech ?
