Autodream1436215442 Posted January 14, 2009 Report Share Posted January 14, 2009 1 all output rest at ground with power off, most factory ign relay, cooling fan relay and fuel pump relay coil have constant power full time. wiring in a G4 now take twice as long because these hidden relays have to be rewire too. 2 after a run and log I want to be able to turn the key off and back on reconnect to the ecu and not having to loose all my markers that I just put on during my run.

You may be getting back feeding issues, auxiliary channels are flywheeled which means current can feed in through these channels and begin to power the ECU . To avoid this problem connect hot fed relays to fuel and ignition auxiliary channels. 2. Do you mean the * or the spacebar marker? Quote Link to comment Share on other sites More sharing options...
