@russian I am not very familiar with the PPC variants. I'd open up my one PPC based eec-V for a look but Ford likes to put random part numbers on things instead of industry PNs.
The chips were designed by Ford's Microelectronics group in Colorado with support from Motorola and Intel and were cross sourced from several manufacturers. From the pocket reference "This reference guide is intended for use by engineers and programmers who design, develop, and program 8061 and 8065...
If you want a moderately accurate description of the systems in the Ford EEC-IV / EEC-V look for ( google ) documents titled similar to: Technical notes on the EEC-IV EEC-Tech-Notes EECTechnical EECIV Inner Workings EEC-EV Pocket Reference The "holy grail" of docs is a Ford pub titled: EEC ARCHITECT...

The Ford EEC-V runs a chip that is somewhat similar to an 8096 from an instruction perspective that includes substantial analog and time base circuits to support ECU duties. The family number is 8065 ( 8061 was in EEC-IV ) and they have bank switched RAM/ROM address space for a 256MB logical space a...

If you can deal with a small dash there is an ST unit wirh LCD
With the VR inputs ( and hall inputs also ) you need to be wary of catching the correct crossing point or the missing tooth will be off by almost 1 tooth.

It also seems that in several instances the STM32F3 series is better suited for automotive ( mixed signal ) use than the F4. I know the power of the F4 is tempting but it sure looks like there are more useable features on the F3 and the discovery board is even cheaper. http://www.st.com/web/en/catal...
