Yeah that's what I also seen was one at a time n whichever guage "won" n received data first would work. But also, it was saying people wanted to hook a wideband or hpt tuners up n do that at once n that wouldnt work, n that actually the aeroforce a would. Oh well I ordered from aeroforce. Was just seeing if people have done it before n if it worked or not. Because they don't sell 3 adapter aeroforce obd2 cables anymore and so I wonder how they run them now..so it seems like they should work for aeroforces.
