wrong
in the situation i mentiond the fuel IS shut off … meaning the only reason the engine is spinning is because its being driven by the wheels
trust me on this, ive seen the wideband reading, ive seen the injector pulse width datalog’s
proof … turbo sho on the way to the nyspeed BBQ. were driving down a rather steep hill, alex backs totaly off the throttle says “watch this” weight of the car is pulling the car down the hill at 40mph …
14.7:1 afr … backfire, backfire, backfire, backfire, wideband maxes out lean, reads “- - -” backfires STOP untill he just barely taps the gas again, repeat results … the car was shutting the fuel off because there was no need for it
also 3rd gen shos shut off the fuel during shifts
again, the car isnt technicly running, in this case its off for a split second in order to soften the shift and save the tranny
theres a difference between engine spinning and engine running
