Steve Posted August 10, 2005 Author Share Posted August 10, 2005 Surely the cig lighter wiring isnt man enough if it wants a 20 amp supply? Quote Link to comment Share on other sites More sharing options...
bromy Posted August 11, 2005 Share Posted August 11, 2005 My instuctions say 10amp, i have spurred off the cigarette lighter (15 amp) and used a inline 10amp fuse Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted August 11, 2005 Share Posted August 11, 2005 Ignition barrel supply. Quote Link to comment Share on other sites More sharing options...
Ian C Posted August 11, 2005 Share Posted August 11, 2005 Mine runs off the power feed to the stock ECU. I think. -Ian Edit - I've got the electronic module one, not the module-in-the-gauge job, doh, different kettle of fish. Quote Link to comment Share on other sites More sharing options...
arnout Posted August 13, 2005 Share Posted August 13, 2005 either from the ecu or the fuel pump. Fuel pump might be best cause the sensor only gets power when the car is actually RUNNING. and not on the ignition switch (which can reduce the life of the sensor) Quote Link to comment Share on other sites More sharing options...
Ian C Posted August 13, 2005 Share Posted August 13, 2005 I thought that running the car when the sensor hasn't got power is what reduces it's life? Not running the sensor when it hasn't got exhaust? You are the AEM expert though -Ian Quote Link to comment Share on other sites More sharing options...
b_have Posted August 13, 2005 Share Posted August 13, 2005 If the sensor is hot before engine is started, it *can* shatter if subjected to exhaust condensation. Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted April 14, 2008 Share Posted April 14, 2008 Just resurrecting this after doing a search, as i want to switch my wideband Innovate LM-1 from its current sig lighter feed to the ECU ign power feed, to obviate any grounding offset problems, and i see that IanC has his from the ECU, and just wanted to ask if this has caused any problems? i presume you are also powering up your emanage via this to? I would imagine that the ECU draws a fair current, so would adding another possible 4amp draw cause any problems? Any electronics people care to comment?
