Luke Wiseman Posted February 13, 2010 Report Share Posted February 13, 2010 Hi everyone, Have just wired my ecu and tried to fire it up. For some reason, my ecu isnt seeing trigger events. When cranking no engine rpm increase, trig signal 1 and 2 remain saying "no" even when cranking. I have checked and double checked wiring. Any ideas? Cheers.

Johann Posted February 13, 2010 Report Share Posted February 13, 2010 Assuming everything is set right from a wiring point of view check the distance of the sensor to the trigger wheel. Should be minimal, about 1 mm. If you are confident that the polarity of the sensors is correct then lower the values of the dreaded arming voltages and set the filter to level 1 or 2. Arming voltages near 0.5 volt at 0 RPM, 1 volt at 1000 RPM, 1.5 volt at 2000 RPM. You might even set them a bit lower than that. You have some more info about the trigger setup? Which sensors used, tooth count and such? Quote Link to comment Share on other sites More sharing options...
Luke Wiseman Posted February 13, 2010 Author Report Share Posted February 13, 2010 All standard 1uz sensors (reluctor type). I think its a 12-1 crank wheel? I tested my CAS with my multimeter and it read 80mV when cranking, so assuming that was right, it wouldnt trigger since the voltage is set at 0.5v? Motor was running a month ago with factory ecu so i don't think there is anything wrong with the sensors. Perhaps a Problem with my ecu?

Luke Wiseman Posted February 15, 2010 Author Report Share Posted February 15, 2010 Have it sorted now, needed to change trigger mode to multi tooth, then back to toyota 1uz. Quote Link to comment Share on other sites More sharing options...
