I only have one o2 Chanel on this unit(less expensive unit) and don't have the money to buy all of them sensors
will have to be happy with 3 Chanel's
Left Bank o2, TPS and RPM.
Just when threw an extensive testing of my fuel pressure/volume, and had a vacuum gauge taped to my windshield,.....but would be nice. Gs gauge would be super Cool........
all of these require a sensor..........the 80 dollar tps broke the bank. Vary limited funds these days
I thing if i buy another sensor it will be drive shaft rpm.
