using two ECU's at once

ok, I've posted before about running the ATTS of a Prelude SH with the hondata system... ok, so it can't be done yet with the OBD1 ecus, but by chance can you splice in an extra connector to hookup 2 ECU's at once? the reason I ask is because if all the sensors are run into the stock P5P ecu and only the ATTS output is hookedup, while the P72 ECU would control the rest of the engine... will the reading from the sensors be screwed up if they drive two ECU's? if so, can I just build a little box to mirror the signals to each ECU? (I am an electrical engineer). anyone know where I can get data sheets of all the sensors used in the 5th generation Prelude SH?
