FW: Electromotive question

[Atkinson, David]

Yup.  It's called a HREIC ("hirec") chip - it's an ASIC developed by
Electromotive (or so they claim...) that determines engine speed,
position and acceleration in hardware.  It stands for High Resolution
Electronic Ignition Controller.  I think you'd have a real tough time
getting your hands on one...  but if you were to design your own...
Not sure about the status of any related patents - it might be
worthwhile to investigate since the use of a device like this makes
programming the ECU so much easier, and you can probably use
a slower, less capable microcontroller (less expensive) with this
approach.

     The electromotive manual says that the tec-II uses some sort of   
other
     processor besides an hc-11 (I think) to calculate fuel and spark
     information, relieving the burden from the microcontroller.  My
     question is does any one know who makes this secondary processor and   

     what its called.
