How about this:
Many Triumph TR8's (as well as Rover 3500s)
have an ECU controlled fuel injection (PI) system.
There are various inputs monitored by the ECU which results in the
varied pulse lengths and pulse repitition rate changes for optimal
performance with minim emmissions. The system and factory ECU do
a credible job, but in the event of a failure in the system, the
owner and car can be left dead on the side of the road.
WHAT I'D LIKE: How about developing a simple overide system which
could be installed in the PI TR8 and switched in when or if a
failure was experienced. The system should be simple and not concerned at
all about emissions levels, but rather it should be of sufficient utility
and control to allow the car to be driven home without damaging the engine.
Such a system would probably require monitoring of at least two inputs:
The amoount of throttle as indicated by the change in the throttle resistance
potentiometer AND the engine speed as a function of the electronic pulses
associated with the distributer.
I'm posting this response also to the TR8 car club list to see if anyone
else there has any ideas or would like to amplify on my thoughts.
