Fuel Injection06WEGO III WIDE-BAND AIR-FUEL RATIO TUNING AIDThe WEGO III is a complete air-fuel ratio metering system with overtwo hours of built in data logging for all carbureted and fuel injectedengines. It features a waterproof, daylight readable blue LED displayfor air-fuel ratio and engine rpm, and has a spare 0-5V analog inputfor sensors such as throttle position or manifold pressure. It is said tobe highly accurate with easy, free air calibration to adjust for sensoraging effects. It has a wide voltage range from 11 to 16V with currentdraw of approximately 1 amp allowing operation from battery or racevehicles without an alternator. The kit includes the WEGOIII unitmeasuring 4" (11.6 cm) long, 2" (5.1 cm) wide and 1/2" (1.3 cm) high.Unit has a built-in USB interface. Comes with a 48" wiring harness, aBosch LSU 4.2 oxygen sensor, matching 18 X 1.5mm weld nut andsoftware that runs under Microsoft Windows 98, ME, XP and Vista.742020 Complete Wego III wide band air/fuel ratio tuning aidIndividual parts741992 Twin Tec WEGO serial interface (for WEGO and WEGO IIonly)742001 Twin Tec PC USB Link interface cable741993 Weld-on nut for exhaust oxygen sensor741994 Socket plug for weld on nutTWIN TUNER FUEL INJECTION CONTROLLERThe Twin Tuner allows you to easily adjust your fuel injection to matchthe requirements of performance parts including camshafts,free flowingexhausts and low restriction air filters.To properly tune an engine youneed to know what fuel trim values are required. The only practicalmeans of doing so is to use an air/fuel ratio metering system. Use themode and up/down push button switches to make fuel trim adjustmentsin the RPM and throttle position ranges required by most applications.You can add up to +30% or subtract down to -20% fuel. The TwinTuner also has an advanced mode, where you can use the optional USBInterface (ZPN 742001) and PC Link Tuner software to make precisefuel adjustments.The PC Link Tuner software uses the same RPM rowsand throttle position columns as the Dynojet Power Commander.Whenyou have already created Dynojet Power Commander files for yourapplications, you can enter the same values into the Twin Tuner tables.Installation takes only 10-15 minutes and is very easy.All access is atthe connector unit of the Delphi ECM.The controller unit is completelyencapsulated and resistant to moisture. Due to its very compact size,4" (10 cm) long x 2" (5 cm) wide and 1/2" (1.3 cm) high, you will nothave a problem finding a place to mount the unit.

Jims has manufactured and assembled all the parts needed for a singlepart number, user-friendly,AFR diagnostic sniffer tool kit for use with the Daytona Twin Tec WEGOAFR Monitoring System. Simply install the WEGO III sensor cable into the new JIMS manifold sniffer.The Jims AFR Diagnostic Sniffer comes complete with heat wrap, wire taps, and clamp for securingthe sniffer to the exhaust system. During testing, the Jims AFR Sniffer gives readings that are virtuallyidentical to the readings from a wide-band sensor mounted in the stock location near the cylinderhead and accurate readings were obtained at above approximately 10% throttle.751113 Jims AFR diagnostic sniffer06-029
