Brad Burnett Posted June 10, 2019 Report Share Posted June 10, 2019 Pretty sure the answer is going to be no. Will most likely have to send the ecu in for repairs. @Adamw or @Simon will need to chime in here. Quote Link to comment Share on other sites More sharing options...

Adde Posted July 18, 2019 Author Report Share Posted July 18, 2019 I recive ecu. You dont find any problems, but signal inj 3 still wrong and car dont work good. Can i log in link software inj timing of each cylinder? Quote Link to comment Share on other sites More sharing options...
Adde Posted July 18, 2019 Author Report Share Posted July 18, 2019 This osciloscope of 2 working cylinders and osc of one working and one bad working cylinder(cyl3). How do you test ecu, if it slill work bad? Quote Link to comment Share on other sites More sharing options...
Simon Posted July 19, 2019 Report Share Posted July 19, 2019 That looks like the 12V supply to the injector is missing. Check at the injector plug you have a good 12V feed. Quote Link to comment Share on other sites More sharing options...
Adde Posted July 19, 2019 Author Report Share Posted July 19, 2019 Its joke? Do you think i dont check 12v supp before send to your service ecu from Ukraine to NZ? I check, all OK, but inj3 still dont work. Quote Link to comment Share on other sites More sharing options...
Ducie54 Posted July 20, 2019 Report Share Posted July 20, 2019 I would be testing the signal out of the ECU not at the injector plug. You would need to find a power source near the ECU tho. Then you can work out if it's a wiring issue. Quote Link to comment Share on other sites More sharing options...
Adde Posted July 20, 2019 Author Report Share Posted July 20, 2019 I cut wire and connect directly to ecu, this osciloscopes makes from ecu. Problem is in ECU not in wiring, but Link repair service dont find it. Quote Link to comment Share on other sites More sharing options...
Ducie54 Posted July 20, 2019 Report Share Posted July 20, 2019 Have you checked to see if the is any damage to the ecu plug. Or best to power the ecu out of the car and join straight on ECU pins. The repair service has been good finding the issues ive had. Quote Link to comment Share on other sites More sharing options...
Adde Posted July 20, 2019 Author Report Share Posted July 20, 2019 If ecu plug will have be damage we dont have any signal on osciloscope. But we have signal and have frequency of signal. I connect dirrectly to ecu and from cyl 1 2 4 we have good signal but from inj 3signal wrong. Tell me why? Quote Link to comment Share on other sites More sharing options...
Ducie54 Posted July 20, 2019 Report Share Posted July 20, 2019 Are you using the test function to check or cranking engine? Quote Link to comment Share on other sites More sharing options...

Ducie54 Posted July 20, 2019 Report Share Posted July 20, 2019 Use the test function. You may have a trigger issue as there are 4 small spikes on that last image. Quote Link to comment Share on other sites More sharing options...
