The wideband narrow band output should NEVER be hooked to the factory narrow band input under any circumstances for any reason.įirst you must unplug the egr valve position sensor from the EGR valve and/or the EGR flow sensor. NEVER use a wideband to simulate a narrowband.
NOTE: A wideband is too slow and not accurate enough to simulate a narrowband. See the Tuning Tips Write Up for more details. If you do not have the ability to add in an additional bung for the wideband you have the option to disable hego2 (driver side) and install the wideband EGR should be pluggedīack in and re-enabled in the tune after WOT fuel has been dialed in and the wideband is no longer needed. NOTE: It IS NOT RECOMMENDED to permanentely remove or disable the EGR unless absolutely neccessary. Typically on EEC-IV this is usually ECU Pin #27. See the ECU Pinout List for which pin is the EGR Valve Position. This input can be reused to datalog a 0-5v input (such as a wideband) when Most all EEC's have a 0-5v analog input used by the egr valve position.
