<strong>Daytona</strong> <strong>Sensors</strong> <strong>LLC</strong>Engine Controls and Instrumentation Systems<strong>Tech</strong> <strong>Note</strong> for Interfacing <strong>WEGO</strong>to Dynojet ® Analog ModuleCAUTION: CAREFULLY READ INSTRUCTIONS BEFORE PROCEEDINGOVERVIEWThe <strong>WEGO</strong> IIID can be interfaced to a Dynojet ®dyno by means of the Dynojet ® analog module.Correctly scaled air/fuel fuel ratio data for two channelscan then be displayed and charted along with otherdyno data in the Dynojet ® WinPEP ® software.For more information about the Dynojet ® analogmodule and WinPEP ® software, please refer to theDynojet ® website at www.dynojet.com.Once installed, the <strong>WEGO</strong> IIID can be used witheasily fabricated exhaust sniffers for automotive andmotorcycle applications described in tech notesavailable on our <strong>Tech</strong> FAQ at www.daytonasensors.comREQUIRED PARTSdyno system must be equipped with theDynojet ® analog module. You will require twounterminated sensor cables available from Dynojet ® . Inaddition to the <strong>WEGO</strong> IIID system, you will also requirea 13.8V regulated power supply capable of supplying aminimum 6 amp current. Appropriate power suppliesinclude P/N 136581 available from Jameco(www.jameco.com) or P/N 72-8142 from MCMElectronics (www.mcmelectronics.com).HOOKUPRefer to Figure 1. You can use this samehookup for any <strong>WEGO</strong> series unit (for single channelunits, only one channel is connected). One Dynojet ®sensor cable is required for each channel. The red wirefor +5V power on the sensor cable is not used andmust be taped up. The grounding strap on the back ofthe analog module (refer to Figure 1-4 in the Dynojet ®analog module documentation) can be used for thecommon dyno ground point shown in Figure 1.Figure 1 – Typical <strong>WEGO</strong> Hookup to Dynojet ® Analog ModuleSENSOR 1 CABLEIDENTIFIED BYYELLOW BANDBOSCHLSU 4.2BOSCHLSU 4.2SENSOR 1 INPUTSENSOR 2 INPUT<strong>WEGO</strong> IIIDSENSOR 1 AFROUTPUTSENSOR 2 AFROUTPUTWHITEBLUEGREENBLACKGREENBLACKCHANNEL 1INPUTCHANNEL 2INPUTDYNOJET ®ANALOGMODULEREDTHIN BLACKHEAVY BLACKGROUNDPOWERSUPPLY+13.8VGNDBLACKDYNO GROUND<strong>Daytona</strong> <strong>Sensors</strong> <strong>LLC</strong>, 933 Beville Road, Suite 101-I, S. <strong>Daytona</strong>, FL 32119 <strong>WEGO</strong> Dynojet® <strong>Interface</strong> <strong>Tech</strong> <strong>Note</strong>(386) 322-7390 www.daytona-sensors.com 3/2011Page 1
