Question about TBI Flood Clear mode

[t3tom]

8v or 16valve? year?
RTM
this only very briefly covered the FSM factory service manual.
sure cranking, there is an (I am) cranking now pin, on all ECUs here. connected to the start/crank lug of the IGN, switch. 8v is pin B11 (blk-yell)

seems cuts fuel 100% why not? be easy to see with a scope.
unflood mode. (keep in mind wot is not calibrated, only the idle switch is. so wot can be 3.4v to 4.75vdc or as high as 5.25vdc but the software sets this only
Firmware, in the CPU.(ECU) 75% is a good guess, as any. my guess is over 3.4vdc as the book shows on 8valve, page below pin a21
Wide open throttle. i'd guess 4v or more, TP pin. I dont think the book tells this. only that it is WOT, crank and injectors stop for clear flood mode.
pin A21 is stated here,

not sure if it monitors RPM, as cranking is 200-300 rpm, about.
but may?, when it sees, over 600 it know engine started, as spark is for sure there. not sure. not me. and not easy to test this.
we now that this works push start (or by gravity) it know engine started, regardless of any crank singles. the 600 rule.
my guess an internal hidden firmware (Running flag)

seems cuts fuel 100% why not? be easy to see with a scope.

I have a pocket Nano oscilloscope but it can only handle up to 10V X 10 using a 10X attenuator probe. Would that represent enough Y range to measure the Fuel injection pulse waveforms? Should the probes be connected to the red and yellow fuel injector pins or connected at the ECU pin side?

And thanks for these diagrams. The vehicle being examined is a 91 G16A 8V US FED spec.
