Soonto_HAS_soop Posted March 6, 2004 Share Posted March 6, 2004 What wire to the ECU do I need to use to wire in an Air/Fuel Ratio gauge? Anyone know, as I don't really want to run it directly off of the lambda wiring. Ben.. Link to comment Share on other sites More sharing options...
Wez Posted March 6, 2004 Share Posted March 6, 2004 47B = AFR #1 48B = AFR #2 Link to comment Share on other sites More sharing options...
TLicense Posted March 6, 2004 Share Posted March 6, 2004 Ben, Have a look at this of off MKIV.com.... http://www.mkiv.com/manual/manualtt/terminals_of_ecm/index.html Looking at that it seems as if it should be either 47B or 48B. Not quite sure what your hoping to see on the gauge, as I'm sure your aware the stock lambda sensor isn't wideband so will pretty much only be accurate around 1 lambda. (So I'm told anyway ) Hope that helps Link to comment Share on other sites More sharing options...

supra dan Posted March 7, 2004 Share Posted March 7, 2004 ive had one of these for a while, bought it before i knew they werent much use. am i right thinking i just have to splice into the wire on terminal 48 then? Link to comment Share on other sites More sharing options...
AMG Posted March 7, 2004 Share Posted March 7, 2004 dont want to hijack your thread but just wondering if it ok to splice say a coolant temp guage in to the correct wire on the ecu or will this confuse anything? I know it does if you try to splice it in to the sensor. Link to comment Share on other sites More sharing options...
