SuperMID installation - help needed!

[landspeed]

Edit : The above is slightly incorrect (after I reset all the values it changed).

I have connected the speed sensor to one of the cars injectors
I have connected the injector sensor to another of the cars injectors.

Results:

The Instantaneous km/l always stays at 17.6. When I go downhill with
engine braking, it changes to 99.9.

The speed sensor wire is actually reading the injector pulses correctly, and
when I go 1 mile (at any speed), the display goes up 1km (as long as I am in 5th gear).

The Injector pulse width (on the top right of the display) is 0.0 all the time, except when it is 0.5,

when going downhil with engine braking.

This means that

- The speed sensor wire is able to 'read' the injector pulses perfectly
- The injector sensor wire is unable to read the injector pulses perfectly
- The injector sensor wire is detecting every firing of the injectors, but
it is unable to detect the length that the injectors are opening. This is
why, even when cruising, or accelerating hard, the instantaneous
economy is staying at 17.6km/l.
- When the car is doing 50km/h (on the SuperMID display), it says that the economy is 17.6km/l, *BUT

THE INJECTOR PULSE = 0.0* still (which makes no
sense).



The above information should be useful to someone who knows how the
SuperMID works, in order to detect what might be going wrong. Is there
any chance the fault is in the SuperMID conversion box, or the SuperMID
itself?

Attached - is a diagram of how I have wired up the SuperMID...
