midnightzxt Posted April 27, 2005 Share Posted April 27, 2005 with the resistor connected to the Vref and the fidle, the fidle line is supposed to have a constant 5 volts. Well it doesn't. The vref seems to be somehow connected to the fuel pump because it turns on and off with the fuel pump. Can someone explain this to me?

mobythevan Posted April 27, 2005 Share Posted April 27, 2005 Is that true? I am not sure what state FIDLE line should set in when the engine is not running. Some of the Extra codes changed the behavior of the FIDLE line during idle time (so modules wouldn't get hot and burn up). Not sure which code changed it and not sure what the correct behavior should be in either case. The most important thing is that it pulses during cranking. James (developer of Extra code) would tell us how that is suppose to work and what code version it changed in. Maybe ask him over on the MSnS_Extra forum.

Tony D Posted April 27, 2005 Share Posted April 27, 2005 may well be, but as long as the MS is powered, the 5vref should be powered. Quote Link to comment Share on other sites More sharing options...
