I have a 91 Mazda protege front wheel drive with the 1.8 l SOHC engine. 
The ECU mounts under the center of the instrument panel. The heater core 
sprung a leak and when the engine stopped running I noticed that I had a 
computer box full of Anti-freeze. After the monumental task of replacing 
the heater core I need to test the ECU. Is there any way to get a 
schematic??Some of the IC's come up on the web for sale but no data 
sheet Same for the Processor. The darn thing has only one injector 
driver and puts all of the injectors in parallel???? The little engine 
is amazing when it runs. Appreciate any help or direction pointers. I 
will replace it with a PIC micro in the near future. I have a lot of 
them left over after a home control project.
