How will you deal with the firmware? Also, do you have the maps for the eprom?
Good luck with this - night be time consuming really cool stuff.

I bought 15 items of the Atmel TS87C51RB2, it's a DIP40 8052 with all Philips/Temic devices and features. I'm going to connect a RS232 driven backlighted external screen to display real time parameters like RPM, temperature.

Firmware: as mentioned I'm writting my own one. I reuse the Bosch map access routines and their math routines. I have a Linux based Bosch map editor and an Eprom emulator which understands these maps. Their routines are well written and extensively tested (and even certified ).

I'm going to have a configurable real-time kernel (already tested) and a background main calculation loop (engine dependent). But I would not be able to share all that because most of people uses Windoz and does not have ROM emulators. It would be cool someone writes a graphical interface to program the maps and to put them into the internal EPROM through the serial connection. For the moment I don't plan to spend time on that.
