Ally V8 Posted December 16, 2006 Share Posted December 16, 2006 Have you checked the connectors on the fuel rail / coolant temp sensors ? Quote Link to comment Share on other sites More sharing options...
Highway_Star Posted December 16, 2006 Share Posted December 16, 2006 Shack, The ECU has various modes and maps, which one it's running with is selected by the tune resistor. Tune resistors Red wire, 180 Ohms, Australia, Rest of world. Green wire, 470 Ohms, UK and Europe - Non Catalyst Yellow wire, 910 Ohms, Saudi - Non Catalyst White wire, 3900 Ohms, USA and Europe - Catalyst Quote Link to comment Share on other sites More sharing options...

jwriyadh Posted December 18, 2006 Share Posted December 18, 2006 Google for "hotwire"or "14CUX" and find the extract from the LR Service training manual, the checklists shown here will not work for hotwire, only flapper. When you have obtained the correct information run through ALL the checks, this identify your problem area(s). Do the checks as shown, at the ECU plug, not the component. Use the wire colours from an appropriate diagram to check correct connections to sensors etc. As you have no lambdas or cats make sure your "tune resistor" is the green one (470 ohms). The hotwire system, despite being Lucas will perform well and reliably. Keep in mind your hotwire system is not new and may have been messed with previously. Enjoy the learning experience. johnw Quote Link to comment Share on other sites More sharing options...
