Up to TWO Analog/Digital Auxillary Inputs – Use External Sensors to Enhance Your Data Capture

Sometimes a LOT isn’t ENOUGH Tie in external sensors (such as Wide Band O2 controllers or Exhaust Gas Temperature (EGT) probe(s)/Amplifier) for even MORE of a good thing …

With TWO Analog 0 to 5 volt inputs BUILT IN you can easily interface with almost all of the popular add-on wide band controllers and other 0-5v style sensors such as Exhaust Gas Temperature (EGT) probe kits*, fuel pressure senders, boost sensors, position sensors, temperature sensors … you choose!

In most cases it’s a simple matter of attaching one (sometimes two) wires to the DashBoss™, setting the response curve as specified by the sensor manufacturer, and then the data is integrated with all other vehicle parameters!

Optional External A/D Sensors: How to Configure and Use the A/D Inputs

Expand your capabilities with a simple hook up! Up to TWO external sensors at once!

This tutorial will show you how to configure and use the DashBoss™ Analog/Digital converter inputs for interfacing with our EGT Single Channel Kit or the DynoJet Wide Band O2 Controller device. The Wide Band Controller, EGT AMPLIFIER OR other sensor MUST have a 0-5v Analog Output for hooking up to the DashBoss™. The tutorial will assume that the Wide Band O2 Controller has been wired up as shown in the manufacturer’s documentation and in accordance with the following diagrams. If you are hooking up a Wide Band 2 unit that you bought from us, then simply plug the two mating connectors together and set it up in your DashBoss™ App on your device by touching the “DynoJet WB2 Presets”.

BE SURE THAT THE EGT AMPLIFIER IS OFF WHEN PLUGGING/UNPLUGGING DASHBOSS FROM THE OBD II PORTTO AVOID DAMAGE TO THE EGT AMPLIFIER!


Where to find 5 volts for sensors


This will depend on the vehicle, but most have a 5 volt reference (Vref) under the hood that runs to all the OEM sensors (ECT, TPS, MAF, MAP, BARO, TPS, etc.).  This can be found by back probing a sensor connector with a multi-meter and finding the steady 5v source … usually you have to have the KEY ON.

Then trace the wire to a convenient place to tap into (it usually runs throughout the wiring harness under the hood) and either splice/solder/heatshrink a new wire OR use a ScotchBlock style connector (NOT recommended just because those types of connectors are rarely weatherproof).

In the above examples using OUR EGT AMPLIFIER AND PROBE KIT, once things are wired up and ready, you can connect your iOS device and start the Dashboss App like you normally would.  Once it’s up and connected, do the following:

  1. Go to External Sensors from the main screen
  2. Choose Port #1 (or #2 depending on which port you wired up to and are configuring)
  3. Choose High Temperature Sensor (since this is EGT)
  4. Set the various limits as shown here:

settingsEGT

These setting are based off the published curve for the EGT amplifier as shown in EGT Amplifier User Manualampcurve-1

The equation we’re using is:  Temperature °C = (Voltage / (0.004 * (1 + 0.02))) – 1 


In the above examples using OUR PRESSURE TRANSDUCER, once things are wired up and ready, you can connect your iOS device and start the Dashboss App like you normally would.  Once it’s up and connected, do the following:

  1. Go to External Sensors from the main screen
  2. Choose Port #1 (or #2 depending on which port you wired up to and are configuring)
  3. Choose Pressure Sensor (since this is a pressure transducer … it can be used for fuel, oil, gas, air, etc.)
  4. Set the various limits as shown here:

EXAMPLE FOUR

If you have only ONE wide band, you only need one “channel” so only two wires (signal/ground pair). You use four wires if you have TWO channels of wide band (such as one each bank of a V engine). SEE PICTURES BELOW FOR AN EXAMPLE OF ONE CHANNEL WIRING WITH THE DYNOJET WIDEBAND 2 ANALOG 0-5V OUTPUT AND SIGNAL GROUND.  CLICK HERE for the instruction manual for your Dynojet Wideband 2 kit …

FORD POWERSTROKE DIESEL FUEL PRESSURE (TRANSDUCER) INSTALLATION

  1. Disconnect Battery cables from the negative posts of the batteries
  2. Remove the driver’s side fitting from the pressure port on the dirver’s side of the fuel filter housing (facing the firewall) … see diagram
  3. Thread the fuel pressure ADAPTER into the fuel filter housing pressure port.  BE SURE TO TIGHTEN THE ADAPTER SO THE O-RING SEALS NICELY.  Don’t over-tighten or damage the O-Ring.
  4. Thread the fuel pressure sensor directly into the female end of the fuel pressure sensor using a MINIMAL AMOUNT of Teflon tape or sealer.  Don’t “goop” it on or over wrap the adapter because there needs to be a GROUND between the sensor and the adapter.  You want just enough to make a nice seal
  5. Finish your wiring and DashBoss installation as per the wiring diagram.
  6. Reconnect the battery cables.

  1. Thread the female end of the -4 AN Fitting (A) into the male end of the 1/8” NPT Fuel Pressure Transducer (B) and tighten.
  2. Thread the male end of the -4 AN Fitting (A) into the female end of the remote line (E)
  3. Install the PRESSURE PORT Adapter (C) as instructed in the separate instruction sheet included with the adapter
  4. Thread the male end of the -4 AN Fitting (D) into the 1/8 NPT port of the PRESSURE PORT Adapter (C).
  5. Thread the female end of the remote line onto the male end of the -4 AN (either straight or elbow depending on your application) fitting (D)
  6. Use the supplied cushion clamp to secure the remote line to a bolt on your firewall, fender well or other convenient location that isolates the transducer from heat and vibration. If you drill holes for mounting the clamp be very careful around wires and hoses. Be sure to know what’s on the “other side” to avoid drilling through a body panel.

Wiring and Connections for the “Do It Yourselfer”

ConnectorParts needed (not included – available separately as “DashBoss™ Connection Kit”):

Molex connector pins – Part #: 43030-007 …. Digikey link to Pins

Molex housing – Part #: 43025-0400 ………… Digikey link to Housing

IMPORTANT NOTE : BE SURE TO DOUBLE CHECK THE CABLE/CONNECTOR DIAGRAM when wiring up your connection kit!. The connector you are wiring is a MIRROR of the diagram presented above (since it is the mating connector!) See diagram below for the MATING CONNECTOR! If you purchased the “DASHBOSS CONNECTION KIT”, the connector will be premade and you just need to match the wire colors and solder/butt connect them.

EGT sensor kits are sold in the shopping site and include an amplifier, a thermocouple probe and a connection kit for connecting to the gateway.  CLICK HERE for more info …
