Does anyone know what voltage and waveform (AC or pulse DC) the TB and TD tacho signals are? And hows many pulses per engine revolution? A screen shot of an oscilloscope would be handy if anyone has one.
Alternatively, does anyone know if an Autometer tach adaptor will control either TB or TD factory tacho's?GQ TB/TD tacho signal. What voltage & waveform?
Wanted:
GQ/GU 3-inch exhaust
Mudnut may know he was looking into an osilliscope last week
04 ST 3lt auto, not enough Mods to keep me happy, but getting there
Sorry, bloke, I've just only ordered a handheld oscilloscope. It will take a week or two to get here. The only other info I have is the link given me for the speedo signal. I will post info as I get it.
My advice is: not to follow my advice.
