The higher voltage would represent both on the single input, unless the ECU code was written for two.
On a 1UZFE with its Karman Vortex, the signal is probably unreadable. Worst case scenario one is on while the other is off. The KV meter creates frequency in a square wave.
actually it depends on which model 1uz you have
if you have one of the later models 96 97 you can run a twin intake no problem but you have to use a piggyback or something to combine the signal
the safc neo will do it no problem at all as it has a twin intake mode
Why waste yr money on that
With twin turbo u need aftermarket ecu
Anyway if u want to do it right
That gets rid of the Maf
Please tell me yr not running orig ecu with
Twin turbo setup
