Tapping into TPS and MAP for Zetronix dataloggin
which wires do i tap into to get the MAP and TPS signals for the zetronix wideband? and is there an easyer way then splicing into the tach to get the RPM signal?
and whats the diff between a normal ground and a sensor ground?

The resistence between the ground points causes a small voltage diffrence.
the sensors are grounded to the same point so there is no voltage offset. The ecu uses the same ground or measures the small voltage at the sensor ground point.

yeah ground your ground where the sensor is grounded too thast way they read the same. thats why most a:f gauges are required to ground to the engine where the ecu is grounded so you get the same readings as the ecu

hmm where is the ecu grounded? this probably explains why my a/f gauge sometimes illuminate some leds around the led it actually should illuminate.
