ae82ted Posted February 19 Report Share Posted February 19 Does the TTXLink use the stock primary O2 sensor as the calculation for close-loop fueling? or do we have to add an external wideband O2 like other plugin ECU does? Quote Link to comment Share on other sites More sharing options...
Vaughan Posted February 19 Report Share Posted February 19 Looking at our schematic the primary O2 sensor is narrowband and so no good for determining anything other than stoich, you will need to add an external wideband for proper Closed Loop Lambda Quote Link to comment Share on other sites More sharing options...
