Actually, the car in question (my 1994 Probe GT) has a normally 
aspirated 24V DOHC V6. No turbo...it was the previous generation 
GT that  had the turbo.

The engine is a 2.5L unit and is built by Mazda. The car itself is 
basically a Mazda MX-6 with Ford bodywork, interior and suspension 
tuning. The engine and engine control system is Mazda's MECS-II 
system.

I'm "hacking" it more for fun than anything. When I say hacking, I 
mean disassembling the program code, determining memory mapping, 
peripheral chip functions, logic flow etc. I've already got quite a 
bit of the hardware figured out and just wanted to know if anyone 
else had been working along the same lines. Lot's of people hack GMs 
ALDL (for instance) but I've seen very little discussion of this nice 
little ECM.

Thanks for the reply.
