Anthony Parle Posted July 24, 2020 Report Share Posted July 24, 2020 I install a G4 plus Thunder wired into a Subaru Impreza 2001 SOHC EJ20. Had the car running for a couple of day then it just died. I have checked the scope log on the ECU and it can no longer see the Cam & Crank sensor, Crazy thing is I can hook a scope to the same 3 wires and it gets the correct signal. The ECU just sees a signal neg 0.3V to 0V were the oscillscope sees the correct trace voltages. Not sure what to look at next I assume its something not set up correct in the set up file. But why did it read correct on set up then not after the engine died. Below is the two images that show you what I mean. Any advise greatly appreciated.

Brad Burnett Posted July 24, 2020 Report Share Posted July 24, 2020 could you add a copy of the most recent calibration? Quote Link to comment Share on other sites More sharing options...
Anthony Parle Posted July 24, 2020 Author Report Share Posted July 24, 2020 Hi Brad, I used what Link had in the sample program for this engine. is this what you want? Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 24, 2020 Report Share Posted July 24, 2020 For that trigger scope, are you sure you clicked the capture button only once the engine was turning over? With your standalone scope, was channel 1 connected to trigger 1 or trigger 2? Quote Link to comment Share on other sites More sharing options...

Adam just hit capture after I was cranking and it was all good, got the correct trigger readings. Thanks for the . My problem can't be the ECU then, will need to look some were else Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 24, 2020 Report Share Posted July 24, 2020 Please do a PC Log of it cranking and attach it here. Quote Link to comment Share on other sites More sharing options...
