Fuel shut off during coast down - ZR-1 Net Registry Forums

*sorry, typo in the headline - it's fuel SHUT off* (can't change the headline)

I found in the shop manual that the LT-5 shuts off fuel delivery completely during extended coast down to protect the catalytic converters.
I observed my instant fuel consumption today and even in long downhills it never reads less then 2L/100km (sorry, metric...). My Audis drop to "0" reading in such situations. What is expected behavior for my 91 Z? Should it also display "0" fuel consumption at a point?
