Default ccm/bcm testing

I have no speed, no mileage (odd) no instant or avg mileage. tbl codes are
32,34,36,38. clear codes still not working. sys lite flashes at times. car starts
runs ( ran 7.72@92 mph at points race this past weekend 1/8 mile track.
I'am using a tech 2 , check veh speed no reading on tech 2. per fsm 1990
section 8D pg 36 ? possible replace ccm/bcm. or can it be tested to see
if it is ok? car has an auto (4l80E) so i can see mph on the transmission control unit.
thanks
