Hi Liteace
We have the Launch431X and I went into measuring blocks but for some reason I couldn't Identify what it was reading usually it say's what your reading but not on this vehicle had something like 00001001? whatever that means, the only one I could Identify engine temp, no clues what the rest ment?
But I need to know why cant we read wideband with pico, thought the scope could measure any sensor, :?: think it's because I want to fix any vehice that comes in with the scope 8)
